Hyflon® PFA 420
全氟烷氧基
Solvay Specialty Polymers
产品说明
Hyflon® PFA is a family of semi-crystalline, melt processable perfluoropolymers which combine excellent mechanical characteristics to unique properties such as chemical inertness, heat resistance, inherent flame resistance, low surface energy and exceptional dielectric properties. PFA resins are designed to retain their properties over a wide range of temperatures (-196/260°C or -320/500°F) and are the material of choice in applications such as linings in the Chemical Process Industry, specialty cables, semiconductor industry, aero space, etc.
Hyflon® PFA 420 is a high molecular weight, low melt flow rate multi-purpose resin designed for pipe, cable and stock shapes extrusion, injection, compression, and transfer molding. Hyflon PFA 420 is an ASTM D3307 - Type II resin.

补充信息
PROCESSING
•Because PFA is corrosive in the melt, machinery used to process Hyflon® is typically lined with nickel content alloys. Clean, reworked materialcan be used up to 25% in weight.
HEALTH SAFETY AND ENVIRONMENT
•Hyflon PFA 420 is a very inert polymer and it is not harmful if used and handled ording to standard processing procedures. If handledinappropriately, it may release harmful toxic chemicals. Please refer to the Material Safety Data Sheets for more information on handling and safety.
PACKAGING AND STORAGE
•Hyflon PFA 420 resin is available in 25 kg (55 lbs) and 500 kg (1102 lbs) packaging. Though it has an indefinite shelf life, it is mended tostore it in a clean area, protected by direct sun light and possible contamination.
