产品说明
KYNAR®760 is a semi-crystalline high molecular weight pelletized polymerof vinylidene fluoride. It
is aversatile engineering plastic with an outstanding balance ofphysical and chemical properties
which it for high performance service in a wide range ofapplications. It is a thermoplastic
fluoropolymercapable of being fabricated in standard processing e Themolecular weight
andmolecular weight distribution have been carefully tailored tosupply a grade suitable for a variety
ofprocessing re and end-use applications.
KYNAR®760 is suitable for the compression molding of block and extrusionof thick monofilaments
andpipe.
Thepowder form of this resin grade is available as KYNAR® 761PVDF.
