attack (hydrolysis) . Polyethers also have lower viscosity and

specific gravity .

Polyester based urethanes have superior cut, tear,

abrasion, oil and solvent resistance .

MDI based products have lower isocyanate odour than

similar TDI types and have superior hydrolysis resistance

and often have higher resilience .

TDI based products are less sensitive to moisture, have

shorter demould times and more user friendly than MDI

product .

Polycaprolactones exhibit good cut, tear, load bearing

and abrasion resistance with the added advantage of

better hydrolysis resistance when compared to Polyesters .

Aliphatic Systems have high resistance to weathering,

high chemical resistance and durability in aggressive

environments .

Polyurea Systems are fast reacting amine terminated

systems used typically in spray applications . These systems

have very good water and chemical resistance .

What are Polyurethanes?

Polyurethane Elastomers are unique design and construction

materials combining many of the advantages of rigid plastics,

metals and ceramics with the

extensibility of rubber .

While it is not claimed that polyurethanes are the answer to

all problems, they are extremely versatile and this is the key

to their widespread and growing use .

The main types of polyurethanes are:

POLYETHER/TDI POLYCAPROLACTONE/TDI

POLYETHER/MDI POLYCAPROLACTONE/MDI

POLYESTER/TDI ALIPHATIC SYSTEMS

POLYESTER/MDI POLYUREA SYSTEMS

These are also known as the “chemical backbones” . Each

has its own performance advantages . Please consult the

Era Polymers Technical Service Department for specific

recommendations .

As a general guide:

Polyethers are recommended for applications where

parts undergo dynamic stress, i .e . they incur lower heat

build-up . They also have advantages in high resilience,

low temperature performance and resistance to water

They are polymeric materials containing urethane groups

produced by the reaction of a polyol with an isocyanate .

They are materials offering a

number of unique properties

which enable products to be

manufactured to meet a range of

demanding applications .

They are materials which can

be processed with low energy

consumption and relatively low

capital outlay for machinery

to yield products which show

cost saving through improved

performance .

Properties of Erapol Elastomers

Polyurethanes compete against

many other materials including rubber,

plastic and metals .

The most common method of

classifying polyurethanes is

according to their hardness.

The diagram (right) shows

how polyurethanes compare

in hardness to other materials.

Diagram 1

1. HardnessErapol elastomers are available in

a wide range of hardness, from 10

Shore A, which is softer than an

eraser, to over 85 Shore D which is

much harder than a golf ball . For

those unfamiliar with this method

of measuring hardness, the pictures

to the right show two typical

Durometers .

Hardness measurement is a useful

tool, however variation in readings by

one or two units can be encountered

when measuring most polyurethane

and rubbers .

Shore A is the most common

hardness scale for use up to 95 – 100

Shore A . Any reading above this

hardness level should be measured

in Shore D scale . The comparison

between the two scales is outlined

above in Diagram 1 .

Analog Hardness Tester Digital Hardness Tester

Taber Abrasion Testing Machine

2. Abrasion ResistanceIn severe wear applications Erapol

elastomers offer outstanding

durability when compared with

rubbers, plastics or even metals .

It should be emphasised that

abrasion resistance is a complex

property . Selection of an appropriate

Erapol elastomer should be based

on actual experience or simulated

service tests . For comparative

abrasion data please see Resistance

Charts on pages 34 – 36 .

Properties of Erapol Elastomers

3. Compression PropertiesErapol elastomers exhibit greater

load-bearing capacity than

conventional elastomers of equal

hardness . This leads to successful

applications such as wheels and

industrial tyres, feed rollers and

stripper springs . In addition to high

load bearing properties in both

tension and compression, Erapol

elastomers also have a high load

bearing capacity in shear .

4. Mechanical PropertiesAt low hardness all elastomeric

materials, including Erapol

elastomers will flex under impact .

As conventional elastomers are

compounded up to higher hardness

they tend to lose elasticity and

crack under impact . On the other

hand, Erapol elastomers when at

their highest hardness levels, have

significantly better impact resistance

than almost all plastics .

The inherent toughness, combined

with the many other outstanding

properties associated with the high

hardness Erapols, leads to many

applications in engineering .

5. Tear StrengthTypically, tear strength is a strong

indication of toughness and

durability . High tear strength leads to

longer service life . Erapol elastomers

in this regard have a distinct

advantage over other conventional

elastomers .

6. ResilienceResilience in conventional elastomers

is generally a function of hardness .

This often undesirable relationship

does not hold true with Erapol

elastomers . Products are available in

a wide range of resilience .

In shock-absorbing elastomer

applications, low rebound

compounds are usually used i .e .

resilience range of 10-40% . For high

frequency vibrations or where quick

recovery is required, compounds

of 40-65% resilience are used . In

general, toughness is enhanced by

high resilience .

7. Low Temperature Properties

Many Erapol elastomers remain

flexible at very low temperatures and

possess outstanding resistance to

thermal shock . The low temperature

resistance of Erapol elastomers has

led to applications below -50°C .

1. Compression Set (ASTM D-395 Method B)

Measures the amount of

permanent deformation a part will

undergo when loaded for a period

of time . In ASTM D-395 Method B

(see above) a load is generated by

imposing a 25% compression on

the sample .

2. Compression Deflection

(ASTM D-575)

This is defined as a compression

test in which the force required

to cause a specified deflection

is determined . Commonly used

strain values for this test are 5%,

10% and 25% .Measures resistance to tear initiation.

Measures tear propagation.

Properties of Erapol Elastomers

8. Tensile PropertiesErapol elastomers are characterised

by high elongation, high tensile

strength and high modulus . This

provides a combination of toughness

and durability, over conventional

elastomers .

Tensile tests are performed on a

tensometer as shown (see right) . In

this test we are interested in the shape

of the overall stress strain curve (see

graphs below) . The more area there is

under the stress-strain curve the higher

the toughness of the material .

We are also interested in various points

along the curve including the ultimate

tensile strength and elongation of the

Erapol elastomers .

Tensile Strength (ASTM Methods D412 and E6)

The maximum tensile stress a

material is capable of developing .

It is the force per unit of the original

cross-sectional area which is

applied at the time of rupture of a

specimen . It is known variously as

breaking load, breaking stress and

ultimate tensile strength . A dumbell

specimen is used for the test .

Elongation (ASTM Method D412)

The extension between two points produced by a tensile force applied to a

specimen . Measured as a percentage of the original distance between the

marks . A dumbell specimen is used for the test . Ultimate elongation is the

elongation at the moment of rupture .

9. Flex PropertiesErapol elastomers resist cracking

under repeated flexing . The rate of

cut growth under flexing may be

reduced by decreasing the thickness

of the part . Unlike other conventional

elastomers, Erapol elastomers can be

used in very thin sections because of

their strength and toughness .

10. Dry Heat ResistanceWhilst many Erapol elastomers

are only suitable for continuous

operation up to 90°C, intermittent

use up to 120°C is possible . Using

specially formulated materials,

continuous operation up to 120°C or

even higher can be achieved .

Properties of Erapol Elastomers

11. Water ResistanceErapol polyether elastomers are

resistant to the effects of water

immersion and have excellent

long-term stability in water up to

50°C . Continuous use in hot water

over 80°C is not recommended for

standard systems .

Water absorption is very low, in

the range of 0 .3-1 .0% by weight

and volume swell is negligible .

This means, for example that

Erapol elastomers can operate at

close tolerance in water lubricated

bearings without fear of seizure .

The moisture vapour transmission

rate of Erapol elastomers is relatively

high and advantage is taken of

this fact in some applications, e .g .

poromeric shoe upper materials .

However, where this property might

be disadvantageous, the advice of

our Technical Service Department

should be sought on the suitability of

Erapol elastomers for any particular

application .

13. Oxygen and Ozone Resistance

Products made from Erapol

elastomers are highly resistant to

degradation by atmospheric oxygen

and ozone . Tests on samples, aged

over 500 hours in an atmosphere

containing 3ppm ozone, show

no attack even while under 20%

strain . Past experience has shown

that materials which resist the

concentration for several hundred

hours are virtually immune to

attack by normal atmospheric

concentrations .

This makes Erapol elastomers highly

successful when employed around

electrical equipment, without the

hardening and cracking often

experienced with conventional

elastomers and indeed many plastics .

14. Oil, Grease and Chemical Resistance

Many rubbers and plastics have

excellent resistance to one or more

specific solvents, oils or chemicals .

Erapol elastomers are resistant to

a wide range of chemicals which

means they can be used in a

multitude of chemical environments

with the exception of strong acids,

alkalis and certain solvents .

As with all materials being examined

for oil and chemical resistance, it

is best to place a sample of the

material in actual service . If this

is not practical, tests should be

devised which simulate actual service

conditions as closely as possible .

For specific information on chemical

resistance, please see the Chemical

Resistance Chart on

page 37 .

12. Electrical PropertiesTypically Erapol elastomers have very

good insulating properties and are

used in potting and encapsulating

applications .

Properties of Erapol Elastomers

15. Radiation ResistanceErapol elastomers are considered

to have better resistance to gamma

ray radiation than conventional

elastomers . They retain a high

proportion of their original flexibility

and toughness when exposed to

gamma radiation .

16. Fire ResistanceErapol elastomers can be formulated

to meet several self extinguishing or

fire resistant specifications .

17. Mould, Mildew, Fungus Resistance

Suitably formulated Erapol

elastomers, usually polyether based,

do not support fungal growth and

are generally resistant to such attack .

This makes them particularly suitable

for tropical environments .

18. Frictional PropertiesErapol elastomers resemble most

plastics and elastomers, in that

friction against non-lubricated

surfaces generally decrease with

increasing hardness . A high

coefficient of friction is valuable for

such products as solid industrial

tyres, feed rollers, drive rollers etc .

High hardness compounds have the

lowest coefficient of friction, and

formulations having very low values

are available . Such formulations are

widely used for bushings, bearings

and wear strips . Wear of shafts and

mating surfaces is minimal, and

usually considerably less than with

plastic materials .

20. MachinabilityErapol elastomers can be

machined using conventional

equipment but you should consult

our Technical Service Department for

more information .

21. Variable Temperature Testing

Sub zero temperature testing

is primarily designed for foam

cryogenic applications where

products are routinely analysed at

temperatures below -165oC . This

equipment also allows Era the

capability of testing elastomers at

elevated temperatures to specific

test methods including Tensile,

Elongation, Compression and Angle

tear (Die C) . Elevated and sub zero

temperature testing has extended Era

Polymer’s testing capabilities .

19. Bonding to other materials

During the initial moulding process

and under controlled conditions,

Erapol elastomers can be bonded

to a wide variety of substrates . High

bond strength can be obtained to

most metals, wood and many plastics .

Bond strength often exceeds the tear

strength of the Erapol elastomers .

The bond strength of Erapol to metal

is usually several times higher than

that of rubber to metal .

It is more difficult to bond cured

Erapol elastomer sheet or moulding

to other materials but special

techniques have been developed to

satisfy most requirements .

Erapol prepolymers will decrease by

reaction with moisture or heat . Partial

drums should be blanketed with dry

nitrogen .

2. Effects of Heating the Prepolymer

The isocyanate (NCO) content of all

prepolymers decreases with time and

especially with exposure to heat . The

table below shows the accumulated

time taken at various temperatures to

degrade prepolymers .

3. ToxicityErapol prepolymers contain reactive

isocyanate groups and should be

handled with care . Avoid inhalation

of vapours and skin contact .

Appropriate personal protective

equipment (PPE) should be worn

and adequate ventilation provided .

For further information consult the

Material Safety Data Sheets .

4. Effects of Curative LevelAll physical properties of Erapol elastomers are sensitive to curative level .

The curative level is often expressed as % theory . The table below shows how

physical properties vary with % theory .

Temperature/oC Time

60 7 days

70 3 days

80 36 hours

90 12 hours

100 8 hoursPhysical Properties Change

Hardness Remains unchanged between 85-100 %

Tensile Strength Maximum physical properties achieved between 90-95% theory .

Tear Strength Maximum properties at 100-105% theory . Significantly lower outside the range .

Abrasion Resistance Remains relatively unchanged between 85-105% theory . Slightly better at 100-105% theory .

Flex Life Maximum property at 100-105% theory .

Elongation Maximum at 100-105% theory .

Compression Set Best at 85-95% theory .
