Polyvinylidene Fluoride
Arkema
产品说明：
KYNAR 720 is a semi-crystalline low molecular weight pelletized polymer of vinylidene fluoride. It is a versatile engineering plastic with an outstanding balance of physical and chemical properties which qualify it for high performance service in a wide range of applications. It is a thermoplastic fluoropolymer capable of being fabricated in standard processing equipment. The molecular weight and molecular weight distribution have been carefully tailored to supply a grade suitable for a variety of processing requirements and end-use applications.
KYNAR 720 is recommended for fine extrusion operations such as monofilament and thin, flat, and blown film. It is also suitable for injection molding applications where very thin cross-sections for intricate design require excellent melt flow characteristics. KYNAR 720 is also suggested for coextrusion of composite constructions and as a base for filled or alloyed KYNAR compounds.
The powder form of this resin grade is available as KYNAR 721 PVDF.
