(N) Nylon has good resistance to organic solvents, oils and gasoline.
Good strength at high temperatures. Material rating: -40° to 200°F. Cold and hot-water
applications. Longtime weathering resistance. Good impact resistance, both single
and repeated. Not recommended for use with ammonium, boric acid, calcium, sulfuric
acid, or hydrochloric acid. F.D.A. listed. Also N.S.F. listed.
(C) Celcon, or acetal copolymer, has high tensile strength and
good impact resistance over a broad temperature range. Translucent white color.
Not affected by continuous hot-water service and works smoothly with metal tubing.
Celcon cannot be recommended for continuous exposure to solutions with a chlorine
concentration greater than 1 ppm. Material is rated at -40° to 200°F in open air,
and rated for 180°F in water
applications. Unaffected by most inorganics, except sulfuric, nitric and hydrochloric
acids. Listed by U.S.D.A. and F.D.A. for coffee, milk and antibiotics. Also N.S.F.
listed. Should not be continuously exposed to sunlight.
(P) Polypropylene has good chemical resistance. Material is rated
at -30 to 215°. Opaque, white color. Unaffected by most weak acids and alkalies.
Below 175°F it has good resistance to organic solvents. Do not use with oxidants
or strong acids or in continuous sunlight. N.S.F. listed. 20% glass filled for improved
stiffness.
(K) Kynar, a polyvinylidene fluoride, has outstanding chemical
resistance for handling highly corrosive fluids. Material rated at -80 to 275°,
with a cloudy, white color. F.D.A. listed, N.S.F. Listed.
