Acrylonitrile - Butadience - Styrene - Class
4-2-2 conforming to ASTM D-1788. Temperature range from -40°
F to 180° F. Excellent resistance to deposit formation. Superior
resistance to sewage and common chemical formulations. Good impact
resistance (many automotive parts, bumpers and panels). ABS can be
joined by cementing, threading and flanging.
Polyvinyl Chloride - Class 12454-B Type 1, Grade
1 to ASTM 1784. Temperature range from -30° F to 140°
F. PVC is the most common and most widely used thermoplastic material.
It resists most acids, strong Alkalis, salts and paraffinic hydrocarbon
solutions. Excellent for industrial chemical and plating systems,
deionized water, irrigation and drainage systems. PVC is not recommended
for use with chlorinated or aromatic hydrocarbons, esters or polar
solvents such as ketones. The material can be joined by cementing,
threading or flanging.
Chlorinated Polyvinyl Chloride - Class 23447-B
Type IV Grade 1 to ASTM D-1784. The physical properties at 73 degrees
F are very similar to PVC. CPVC has a slightly better chemical resistance
and has a higher temperature range to 210° F. It is not recommended
for use with chlorinated or aromatic hydrocarbons, esters or polar
solvents such as ketones. The material can be joined by cementing,
threading or flanging.
Polypropylene - Type 1 to ASTM D-4101 class PP10-B67154.
Temperature range from - 30° F to maximum 180° F but
at this temperature we recommend it's use only with water or drainage.
PP is the lightest of all plastics. Resistant to organic solvents,
acids and alkalis. It is not recommended for oxidizing acids, chlorinated
hydrocarbons or aromatics. Mostly used for sulfur-bearing materials,
saltwater solutions, crude oil and low pressure gas systems. PP
can be joined by thermo-seal fusion, threading or flanging.
Polyvinylident Fluoride - ASTM D-3222 having a temperature
range of -80° F to 280° F. The strongest, heaviest
and most abrasion resistant of the thermoplastic materials. PVDF
is resistant to most acids, bases and organic solvents and is the
only thermoplastic resistant to wet or dry chlorine, bromine and
other halogens. PVDF can be joined by thermo-seal fusion, threading
or flanging.
A terpolymer elastomer made from ethylene-propylene diene monomer.
Recommended for water, chlorinated water, dilute acids, alkalines,
alcohols and ozone. Not recommended for petroleum oils, strong acids
and alkalines. EPDM has a temperature range from -20° F to
230° F.
Fluorocarbon Elastomer - Recommended for hydrocarbon service,
mineral acids, salt solutions, chlorinated hydrocarbons and petroleum
oils. Viton has the broadest temperature range of the elastomers
from -20° F to 300° F but should not be used in steam
service
(BUNA-N) - A copolymer of butadiene and acrylonitrile.
Has good resistance to solvents, petroleum oils and fluids, di-ester
lubricants, ethylene glycol based fluids, aliphatic hydrocarbons
and aromatic solvents. It should not be used with acetone and methyl
ethyl ketone, chlorinated hydrocarbons, ozone or nitro hydrocarbons.
Temperature range from -20° F to 180° F.
A chlorosulfonated polyethylene elastomer has good resistance against
nitric, hydrofluoric and sulfuric acids, aliphatic hydrocarbons
and aromatic solvents. It is not recommended for exposure to concentrations
oxidizing acids, esters, ketones, chlorinated, aromatic and nitro
hydrocarbons. Temperature range from -20° to 200°
F.
A chlorinated synthetic rubber elastomer. It is flame resistant
and resists animal and vegetable oils. Recommended for food and
beverage service. Normally not effected by moderate chemicals, fats,
greases and many oils and solvents. Neoprene is not recommended
for strong oxidizing acids, esters, ketones, hydraulic fluids, chlorinated
solvents and aromatic hydrocarbons. Temperature range from -20°
F to 160° F.
Polytetrafluoroethylene - A self lubricating compound.Resistant
to almost all chemicals and solvents and has a very high thermal-stability,
also nonflammable. Temperature range of -20° F to 400°
F.
