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.
