CGM-031 Series
A. Description
PTFE powders with medium particle size for compression molding.
B. General Properties of PTFE
l Excellent chemical inertness
l Outstanding resistance to chemical corrosion, such as strong acid, alkali, strong oxidant, etc.
l Exceptional resistance to high & low temperature, and to abrasion.
l Can be used at temperature range from -200~250℃ for a long period.
l Superior electric insulation, which is not affected by temperature and frequency.
l Non-adhesive to all other materials.
l Non-absorption of moisture
l Flame retardation.
C. Main application
To be made into rods for skivings, gaskets, and parts, etc by compression molding widely used in chemical, mechanical, petroleum, pharmaceutical, electronics, and optical industries.
