Polyvinylidene Fluoride (PVDF) Specifications

Description

Polyvinylidene Fluoride (PVDF) offers excellent corrosion and chemical resistance at both ambient and elevated temperatures. PVDF is also inherently UV stable, mechanically tough, abrasion and flame resistant. 1000 is a whiter grade of PVDF than 740.

Applications

Chemical Process/Storage • Fluid handling • Semiconductor equipment • Fire-safe componentry • DI Water Systems

Advantages of Polyvinylidene Fluoride (PVDF)

High purity • Flame resistant • Easy to machine • Excellent weatherability • Resin meets the requirements of FDA, USDA, USPXX Class VI, 3A, UL, V-0, FM 4910

Manufacturing Capabilities

Rod: 1/8” to 15” diameter • Sheet (Extruded): .030” to 4” thick • Sheet (Comp. Molded): 1/8” to 4” thick • Sheet (Fabric Backed): .060” to 3/16” thick • Film: .002” to .029” thick • Tube: 11/8” to 12” O.D. (custom basis) • Welding Rod: 1/8” and 5/32” diameter

Color/Grades

740/2850 - Natural Beige (custom colors available) • 1000 HD - Natural White
