INTRODUCTION

This chemical resistance guide has been compiled to assist the

piping system designer in selecting chemical resistant

materials. The information given is intended as a guide only. Many

conditions can affect the material choices. Careful

consideration must be given to temperature, pressure and chemi-

cal concentrations before a final material can be selected.Thermoplastics’ and elastomers’ physical characteristics are more

sensitive to temperature than metals. For this reason, a rating chart

has been developed for each.

MATERIAL RATINGS

FOR THERMOPLASTICS & ELASTOMERS

Temp. in °F = “A” rating, maximum temperature which

is recommended, resistant under normal

conditions

B to Temp. in °F = Conditional resistance, consult factory

C = Not recommended

Blank = No data available

MATERIAL RATINGS FOR METALS

A = Recommended, resistant under normal

conditions

B = Conditional, consult factory

C = Not recommended

Blank = No data available

Temperature maximums for thermoplastics, elastomers and met-

als should always fall within published temp/pressure ratings for

individual valves. THERMOPLASTICS ARE NOT RECOM-

MENDED FOR COMPRESSED AIR OR GAS SERVICE.

This guide considers the resistance of the total valve assembly as

well as the resistance of individual trim and fitting materials. The

rating assigned to the valve body plus trim combinations is al-

ways that of the least resistant part. In the cases where the valve

body is the least resistant, there may be conditions under which

the rate of corrosion is slow enough and the mass of the body

large enough to be usable for a period of time. Such use should

always be determined by test before installation of the compo-

nent in a piping system.

In the selection of a butterfly valve for use with a particular chemi-

cal, the liner, disc, and stem must be resistant. All three materials

should carry a rating of “A.” The body of a properly functioning

butterfly valve is isolated from the chemicals being handled and

need not carry the same rating.

THERMOPLASTICS & ELASTOMERS

ABS — Acrylonitrile Butadiene Styrene Class 4-2-2 conforming

to ASTM D1788 is a time-proven material. The smooth inner sur-

face and superior resistance to deposit formation makes ABS drain,

waste, and vent material ideal for residential and commercial sani-

tary systems. The residential DWV system can be exposed in ser-

vice to a wide temperature span. ABS-DWV has proven satisfac-

tory for use from -40°F to 180°F. These temperature variations can

occur due to ambient temperature or the discharge of hot liquids

into the system. ABS-DWV is very resistant to a wide variety of

materials ranging from sewage to commercial household chemi-

cal formulations. ABS-DWV is joined by solvent cementing or

threading and can easily be connected to steel, copper, or cast

iron through the use of transition fittings.

CPVC — Chlorinated Polyvinyl Chloride Class 23447-B, formerly

designated Type IV, Grade 1 conforming to ASTM D-1784, has

physical properties at 73°F similar to those of PVC, and its chemi-cal resistance is similar to or generally better than that of PVC.

CPVC, with a design stress of 2000 psi and maximum service

temperature of 210°F, has proven to be an excellent material for

hot corrosive liquids, hot or cold water distribution, and similar

applications above the temperature range of PVC. CPVC is joined

by solvent cementing, threading or flanging.

PP (Polypropylene) — Type 1 Polypropylene is a polyolefin, which

is lightweight and generally high in chemical resistance.

Although Type 1 polypropylene conforming to ASTM D-2146 is

slightly lower in physical properties compared to PVC, it is chemi-

cally resistant to organic solvents as well as acids and alkalies.

Generally, polypropylene should not be used in contact with strong

oxidizing acids, chlorinated hydrocarbons, and aromatics. With adesign stress of 1000 psi at 73° F, polypropylene has gained wide

acceptance where its resistance to sulfur-bearing compounds is

particularly useful in salt water disposal lines, crude oil piping, and

low pressure gas gathering systems. Polypropylene has also

proved to be an excellent material for laboratory and industrial

drainage where mixtures of acids, bases, and solvents are involved.

Polypropylene is joined by the thermo-seal fusion process, thread-

ing or flanging. At 180°F, or when threaded, PP should be used for

drainage only at a pressure not exceeding 20 psi.

PVC — Polyvinyl Chloride Class 12454-B, formerly designated

Type 1, Grade 1. PVC is the most frequently specified of all ther-

moplastic materials. It has been used successfully for over 30 years

in such areas as chemical processing, industrial plating, chilled

water distribution, deionized water lines, chemical drainage, andirrigation systems. PVC is characterized by high physical proper-

ties and resistance to corrosion and chemical attack by acids,

alkalies, salt solutions, and many other chemicals. It is attacked,

however, by polar solvents such as ketones, some chlorinated

hydrocarbons and aromatics. The maximum service temperature

of PVC is 140°F. With a design stress of 2000 psi, PVC has the

highest long-term hydrostatic strength at 73°F of any of the major

thermoplastics being used for piping systems. PVC is joined by

solvent cementing, threading, or flanging.

PVDF (Polyvinylidene Fluoride) — KEM-TEMP (KYNAR® ) is a

strong, tough and abrasion-resistant fluorocarbon material. It re-

sists distortion and retains most of its strength to 280°F. It is chemi-

cally resistant to most acids, bases, and organic solvents and is

ideally suited for handling wet or dry chlorine, bromine and otherhalogens. No other solid thermoplastic piping components can

approach the combination of strength, chemical resistance and

working temperatures of PVDF. PVDF is joined by the thermo-

seal fusion process, threading or flanging.

EPDM — EPDM is a terpolymer elastomer made from ethylene-

propylene diene monomer. EPDM has good abrasion and tear re-

sistance and offers excellent chemical resistance to a variety of

acids and alkalines. It is susceptible to attack by oils and is not

recommended for applications involving petroleum oils, strong

acids, or strong alkalines. It has exceptionally good weather aging

and ozone resistance. It is fairly good with ketones and alcohols

and has an excellent temperature range from -20°F to 250°F.

HYPALON® (CSM) — Hypalon has very good resistance to oxi-

dation, ozone, and good flame resistance. It is similar to neoprene

except with improved acid resistance where it will resist such oxi-

dizing acids as nitric, hydrofluoric, and sulfuric acid. Abrasion re-

sistance of Hypalon is excellent, about the equivalent of nitriles.

Oil and solvent resistance is somewhat between that of neopreneand nitrile. Salts have little if any effect on Hypalon. Hypalon is not

recommended for exposure to concentrated oxidizing acids, es-

ters, ketones, chlorinated, aromatic and nitro hydrocarbons.

Hypalon has a normal temperature range of -20°F to 200°F.

NEOPRENE (CR ) — Neoprenes were one of the first synthetic

rubbers developed. Neoprene is an all-purpose polymer with many

desirable characteristics and features high resiliency with low com-

pression set, flame resistance, and is animal and vegetable oil

resistant. Neoprene is principally recommended for food and bev-

erage service. Generally, neoprene is not affected by moderate

chemicals, fats, greases, and many oils and solvents. Neoprene is

attacked by strong oxidizing acids, most chlorinated solvents,

esters, ketones, aromatic hydrocarbons, and hydraulic fluids. Neo-

prene has a moderate temperature range of -20°F to 160°F.

NITRILE (NBR) — (BUNA-N) is a general purpose oil-resistant

polymer known as nitrile rubber. Nitrile is a copolymer of butadi-

ene and acrylonitrile and has a moderate temperature range of

-20°F to 180°F. Nitrile has good solvent, oil, water, and hydraulic

fluid resistance. It displays good compression set, abrasion resis-

tance and tensile strength. Nitrile should not be used in highly

polar solvents such as acetone and methyl ethyl ketone, nor should

it be used in chlorinated hydrocarbons, ozone or nitro hydrocarbons.

FLUOROCARBON (FKM) (VITON® ) (FLUOREL® ) — Fluorocar-

bon elastomers are inherently compatible with a broad spectrum

of chemicals. Because of this extensive chemical compatibility,

which spans considerable concentration and temperature ranges,

fluorocarbon elastomers have gained wide acceptance as a ma-terial of construction for butterfly valve o-rings and seats. Fluoro-

carbon elastomers can be used in most applications involving

mineral acids, salt solutions, chlorinated hydrocarbons, and pe-

troleum oils. They are particularly good in hydrocarbon service.

Fluorocarbon elastomers have one of the broadest temperature

ranges of any of the elastomers, -20°F to 300°F; however, they are

not suited for steam service.

TEFLON® (PTFE) — Polytetrafluoroethylene has outstanding re-

sistance to chemical attack by most chemicals and solvents. PTFE

has a temperature rating of -20°F to 400°F in valve applications. PTFE,

a self lubricating compound, is used as a seat material in ball valves.

PEEK (Polyetheretherketone) — PEEK is a high-performance

engineered thermoplastic which can be used above the usefulrange of PTFE. PEEK has physical characteristics approaching

some metals (approximately 30K tensile) and has excellent resis-

tance to a wide range of organic and inorganic chemicals. PEEK

can be used up to 550°F and is an excellent choice for heat trans-

fer fluids, steam and hydrocarbon services.

GRAPHITE — Graphite is the packing and seal material of choice

for most fire-rated products, primarily because of its high tem-

perature rating of approximately 2000°F. Graphite has excellent

chemical resistance, can retain compressibility at all temperatures

and has a low coefficient of friction. Graphite is not recommended

for use in strong oxidizing atmospheres.

METALS USED IN VALVES & FITTINGS

ALUMINUM — A non-ferrous metal, very lightweight, approxi-

mately one-third as much as steel. Aluminum exhibits excellent

atmospheric corrosion resistance, but can be very reactive with

other metals. In valves, aluminum is mainly used as an exterior

trim component such as a handwheel or an identification tag.

COPPER — Among the most important properties of wrot cop-

per materials are their thermal and electrical conductivity, corro-

sion resistance, wear resistance, and ductility. Wrot copper per-

forms well in high temperature applications and is easily joined by

soldering or brazing. Wrot copper is exclusively used for fittings.

BRONZE — One of the first alloys developed in the bronze age is

generally accepted as the industry standard for pressure-rated

bronze valves and fittings. Bronze has a higher strength than purecopper, is easily cast, has improved machinability, and is very easily

joined by soldering or brazing. Bronze is very resistant to pitting

corrosion, with general resistance to most chemicals less than

that of pure copper.

SILICONE BRONZE — Has the ductility of copper but much more

strength. The corrosion resistance of silicon bronze is equal to or

greater than that of copper. Commonly used as stem material in

pressure-rated valves, silicon bronze has greater resistance to

stress corrosion cracking than common brasses.

ALUMINUM BRONZE — The most widely accepted disc mate-

rial used in butterfly valves, aluminum bronze is heat treatable and

has the strength of steel. Formation of an aluminum oxide layer on

exposed surfaces makes this metal very corrosion resistant. Notrecommended for high pH wet systems.

BRASS — Generally good corrosion resistance. Susceptible to

de-zincification in specific applications; excellent machinability.

Primary uses for wrot brass are for ball valve stems and balls, and

iron valve stems. A forging grade of brass is used in ball valve

bodies and end pieces.

GRAY IRON — An alloy of iron, carbon and silicon; easily cast;

good pressure tightness in the as-cast condition. Gray iron has

excellent dampening properties and is easily machined. It is stan-

dard material for bodies and bonnets of Class 125 and 250 iron

body valves. Gray iron has corrosion resistance that is better than

steel in certain environments.

DUCTILE IRON — Has composition similar to gray iron. Specialtreatment modifies metallurgical structure, which yields higher

mechanical properties; some grades are heat-treated to improve

ductility. Ductile iron has the strength properties of steel using simi-

lar casting techniques to that of gray iron.

CARBON STEEL — Very good mechanical properties; good re-

sistance to stress corrosion and sulfides. Carbon steel has high

and low temperature strength, is very tough and has excellent

fatigue strength. Mainly used in gate, globe, and check valves for

applications up to 850°F, and in one-, two-, and three-piece ball valves.
