THE VERSATILE ELASTOMER
Overall product description
The general term ethylene-propylene rubber refers to two different kinds of
polymers:
n EPM represents a copolymer from ethylene and propylene monomers;
EPM is entirely saturated and normally vulcanized by means of organic
peroxides. Sometimes also radiation cure is applied.
n EPDM denotes a terpolymer based on three monomers: ethylene,
propylene and a non-conjugated diene; EPDM grades have a residual
unsaturation in the side chains and can therefore be cured with sulfur
and accelerators. Its aging resistance is distinctly better than that of
Natural Rubber, SBR and Butadiene Rubber.
The molecules of both EPM and EPDM have a completely saturated hydro-
carbon backbone, through which excellent ozone resistance and very good
resistance to aging and weathering are achieved.
Key properties of ethylene-propylene elastomers:
n The lowest density (0.86 g/cm3) of all the
commercially available rubbers
n Very good resistance to heat and oxidation
n Very good resistance to ozone and weathering
n Good chemical resistance
nGoodlowtemperatureflexibility(dependingonethylenecontent)
n Good electrical insulation properties
n Good vulcanizate physical properties (stress-strain behavior,
compression set)
n Can be molded, extruded, or calendered
nFastandefficientmixingwithadditives
nAbilitytoaccepthigherfillerloadingsthanotherelastomers
The properties of the raw rubber and the corresponding vulcanizates are
directlyinfluencedbytherubberpolymerstructure:
n molecular weight
n molecular weight distribution
n composition
n crystallinity
n distribution of monomer units within a chain
n the extent of long-chain branching
These properties are directly related to the polymerization conditions and
catalyst system used in the EP rubber manufacturing process. By varying the
reaction parameters, one can obtain a wide range of properties, suitable for a
large number of applications. The production of a broad range of high quality
synthetic rubber grades of this type is made possible by a thorough under-
standing of the relationship between the process variables and the resulting
product properties.
Main criteria for the design of EP(D)M rubbers are:
n Mooney viscosity
n Ethylene/propylene ratio
n Diene content
n Oil content and oil type
n An example of the wide range of successful applications: LANXESS EP(D)M helps that modern constructions do not only look spectacular, but remain
permanently operational. Thanks to excellent ozone and weather resistance.

Chemistry of EPDM terpolymers
To produce a sulfur-curable rubber, a non-conjugated diene is introduced as
the third monomer during polymerization. Appropriate third monomers con-
tain one double bond which takes part in the polymerization and one which
does not. This results in pendant unsaturation which serves as crosslinking
sites without affecting the saturated main chain. Terpolymers from LANXESS
use ethylidene norbornene (ENB) or dicyclopentadiene (DCPD) as the third
monomer.
Polymer properties such as rate of cure and degree of crosslinking depend
on the type and amount of diene. Grades with different amounts of third
monomer are offered to meet requirements in a wide range of applications.
Structure of EP(D)M
Chemistry of EPM copolymers
Keltan® copolymers are produced by copolymerization of ethylene and
propylene.
Distribution of the co-monomer propylene can vary from random to alterna-
ting. The function of propylene is to disrupt long sequences of ethylene and
prevent them from crystallizing.
n At high propylene levels (above 50 percent), only short ethylene
sequences exist in the polymer chain so crystallinity is absent
n At low propylene levels (e.g. below 40 percent), a small amount
of crystallinity is present which provides the EPM with green strength
As mentioned above, sulfur vulcanization cannot be used to crosslink EPM
since no unsaturation exists. On the other hand, EPMs are attractive, since
the aging resistance of EPM is even better than that of EPDM due to the lack
of unsaturation in the rubber. Peroxide cure is mainly used to overcome this
dilemma.
Peroxide curing of EPM ismore efficient at high ethylene content due to‚
reduced chain scission which occurs at the tertiary carbon atoms of the
propylene units.

SUSTAINABLE EP(D)M
Innovation: Keltan® ACETM technology
Full grade slate capability.
LANXESS Elastomers has developed Keltan® ACETM catalyst technology, a
new versatile and high active catalyst for EP(D)M production. The Keltan®
ACETM catalyst system is the first advanced catalyst system that allows
production of a complete EP(D)M grade portfolio with products that
perform identical to EP(D)M grades produced by Ziegler-Natta catalysts.
This EP(D)M grade portfolio covers the widest range of composition and
molecular weights, including high ENB grades, oil extended grades and
continued benefits from the LANXESS proprietary Controlled LongChain
Branching technology.
Product diversification.
In addition, the Keltan® ACETM catalyst technology creates opportunities
to develop products that are not attainable with Ziegler-Natta or classical
metallocene catalyst technologies. An example of such new product
opportunities is EP(D)M with a high VNB content. Such products offer
the possibility to either reduce peroxide levels in a compound or increase
compound loading and moreover it offers the possibility to produce
vulcanizates having improved physical properties.
Keltan® ACETM technology also contributes to the LANXESS objectives
regarding sustainability:
n reduced energy requirement
n elimination of a catalyst waste stream
by avoiding the need for deashing
n elimination of chlorine residues in the polymer
n Keltan® is committed to increase the eco-friendliness of rubber:
New catalyst technology and bio-based EP(D)M.

being a unique bio-based Elastomer.
LANXESS TRP has done this to test firstly the market’s response to the
need for bio-polymers and secondly to pioneer the reduction in fossil fuel
dependence. From a process point of view we have also crossed the
threshold of proving that this translation from fossil to bio-sourced is feasible
and achievable.
As of October 2011our production of Keltan® Eco is a fact.

Automotive industry
This is by far the largest application segment, ranging from solid and sponge
automotive body sealing to „under the hood“ applications like coolant hoses,
airco hoses, brake parts, belts or engine mounts and some others like wind-
shield wipers.
Themajorityoftheextrudedprofilesaremadebypressure-lesscontinuous
cure. For these products the emphasis is on requirements such as low com-
pression set and good retention of heat-aged physical properties. Based on
the need for higher end product reliability and extended service life, there is a
growingdemandforbettersurfacefinish.
The product should be free from porosity, fast curing, and should adhere well
totextileflockandmetal.Highmodulusisrequiredforoptimumsealingforce,
to prevent leakage through window surrounds and to minimize wind noise
from window seals.
The growing demand for nitrosamine-free compounding prompted the
need for faster curing EP(D)M types that should allow the formulation of cure
systems which are free from bloom and iridescence.
TAILORED SOLUTIONS
n Keltan® meets the highest requirements. E.g. for hose assemblies for air conditioners1

siderable technological advance, and improves long term performance. Due
to their superior water, ozone and weathering resistance, such membranes
have proven longevity, and are endorsed by a track record over 35 years.
Sincevulcanization forbuildingprofiles takesplace inpressurelesscontin-
uous curing equipment, high molecular weight EP(D)M provides good
collapse or distortion resistance during the curing step. Glazing gaskets and
buildingprofilesmustretainhighelasticsealing forcesoverawidetempe-

Plastics modification
Inplastic-modifiedrubber,thermoplasticelastomers(TPE)orthermoplastic
vulcanizates (TPV), EPM/EPDM is the main component and is responsible
for the required physical properties of the end product.
The elastomer component should provide:
n Maximum elastic properties improvement per unit volume
nEfficientdynamicvulcanization
n Contribute to a uniform dispersion of small, highly cross-linked
particles
n Allow the compound designer full freedom in color selection
TPEs provide functional performance and properties similar to conventional
thermosetrubberproducts,butcanbeprocessedwiththespeed,efficiency
and economy of thermoplastics.
The plastic phase imparts stiffness to the blends, enables plastic-like pro-
cessing and recyclability, and eliminates the need for vulcanization. Keltan®/
polyolefinblendsarefindinggrowingapplicationsinareassuchasautomo-
tive parts, consumer products, wire and cable, building and construction
and mechanical goods. The automotive sector is currently the largest mar-
ket for these materials. Examples include soft exterior parts, such as fascia
covers, air ducts, body side moldings, window and body seals.
