Uses and Applications

PVDF — known commercially as Kynar® — is the toughest and most durable pipe lining manufactured by Resistoflex. It is extremely abrasion resistant and features a high thermal expansion coefficient. It is commonly used for demanding applications, including halogen and high-strength acid handling at temperatures up to 275°F (135°C).

Because of the above characteristics, PVDF-lined pipes and fittings are commonly used in the pulp and paper, chemical processing and electronics industries. Common substances that are used with Kynar® pipe include chlorine gas, bromine gas, H2SO4 (up to 98%) and methyl chloride. For detailed specifications and more information about potential Kynar® fittings’ applications, contact a SEMCOR representative to request a product data sheet.
