RUBBER LININGS SOFT NATURAL RUBBER - Good resistance to most inorganic chemicals with the exception of strong oxidizing agents. Exhibit outstanding abrasion resistance and expand and contract with the thermal variations of the metal substrate. SEMI-HARD AND HARD NATURAL RUBBER - Better chemical and heat resistance than soft natural rubber. Wide application in organic and inorganic acids and chlorine gas. Specific grades have excellent permeation resistance and heat resistance to 200°F. [view product chart] TRIFLEX® - Three ply natural rubber lining (soft-hard-soft) that has excellent chemical and abrasion resistance. The semi-hard rubber center layer provides a non-permeable barrier and the soft cushion allows maximum adhesion to steel. [view product chart] NEOPRENE - A synthetic base elastomer with some physical properties similar to natural rubber. Superior to natural rubber in resistance to heat, ozone, sunlight, weather, flame and oil. [view product chart] BUTYL - Good resistance to acids and caustic solutions up to 200°F. Exceptional resistance to gaseous diffusion. Recommended for applications that require ozone, sunlight and aging resistance. [view product chart] CHLOROBUTYL - Properties similar to butyl but easier to apply. Heat resistance good to 200°F. Unaffected by cold weather or rapid temperature changes. Strongly recommended for super phosphoric acid and sodium hypochlorite. [view product chart] NITRILE - Good resistance to greases, oils, petroleum hydrocarbons and other non-polar solvents. Unaffected by rapid temperature changes and have good heat resistance to 200°F. HYPALON® - Good resistance to high concentrations of sulphuric and nitric acids. Good heat, weather, ozone and abrasion resistance. HYPALON® is a registered trademark of E.I.DuPont de Nemours and Co., Inc. [view product chart] EPDM - Similar to butyl plus good resistance to steam and oxygenated solvents such as acetone, methyl ethyl ketone and ethyl acetate. Good resistance to sunlight, ozone and heat.
