PVDF granule/polyvinylidene /PVDF resin /PVDF powder
PVDF injection grade granule, could be used to produce valve, gasket, rod, water-treating membrane etc.
ppearance is translucent or white powder or granule, molecular chain arrangement between close together, and have strong hydrogen bonds, oxygen index was 46%, long-term use of temperature for - 40 ~ 150 ℃.
PVDF is a kind of high strength, corrosion resistant material, is usually used in the manufacture of pipes
PVDF applications mainly concentrated in the petroleum chemical industry, electrical and electronic and fluorine carbon coating three areas
