TECHNICAL DESCRIPTION
Kynar® is a high molecular weight crystalline thermoplastic polymer of vinylidene fluoride -- PolyVinyliDene Fluoride or PVDF.
see also datasheets for:
Static-Control PVDF | Flame-Retardant Kynar PVDF

GENERAL PROPERTIES
Kynar® has excellent corrosion and chemical resistance and performs in many applications up to 300°F (149°C). It is used extensively in chemical processing applications because of its unique combination of properties. Kynar® PVDF possesses excellent chemical resistance, is tough and durable, and is easily fabricated into finished parts.

KEY PROPERTIES
• Good thermal stability • High tensile strength • High impact resistance • Excellent UV resistance • Extremely high purity

AGENCY / REGULATORY CONSIDERATIONS
When specified, PVDF stock shapes may be made from Kynar® 740 resin which complies with FDA regulation 21 CFR 177.2510, USDA, USP XX Class VI, 3A sanitary standards and meets ASTM D3222 resin specifications.

TYPICAL APPLICATIONS
• Tanks & Process Equipment • Tank Linings • Pump & Valve Components • Pipe Flanges & Spacers • Components for Wet Process Stations • Food Trays for High Heat Applications
