产品说明
KYNAR® 760 is a semi-crystalline high 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® 760 is suitable for the compression molding of block and extrusion of thick monofilaments
and pipe.
The powder form of this resin grade is available as KYNAR® 761 PVDF.
