Chemicals, oils and heat, taken together or individually, present critical and unique sealing applications. Sealing problems can be avoided by selecting sealing materials suited to the rigors of these applications.

Style #501 sheet rubber, made with VITON® fluoroelastomer, is a high-performance product resistant to heat, oils, fuels, numerous acids and other chemicals.

• ASTM D2000-2HK-710-B37-Z1
• (Z1 equals durometer of 75 ±5 Shore A)

Style #502 will be used in sealing applications that require resistance to extreme temperatures (-75 to 400 degrees F), high ozone concentrations, and high ultraviolet content. This material also contains only ingredients listed in FDA CFR 177.2600 “Rubber articles intended for repeated use in contact with food.

Style #505 is a branded, chlorinated polyethylene (CPE) sheet rubber product. CPE has excellent resistance to many chemical groups such as oils, acids, bases and alcohols. CPE is also very resistant to oxidation, heat and ozone.

• ASTM D2000-2CE-718-B15

Style #509 is a branded, chloro-butyl sheet rubber product, also referred to as "Butyl" sheet.
