Product use:

DS702: mainly used in pipes, pumps, valves, tank lining, diaphragm, joints, some bearings, etc.

DS701: mainly used for pipe, wire insulation layer, film and various parts;

DS700: for extrusion processing of general plastics, mainly used in cable insulation, multi-core cable sheath, etc.

DS708: mainly used in aviation, aerospace, chemical industry, faster cable extrusion, for most of the use without high stress cracking is more economical.

Note: Processing above 425 ℃ should be avoided so as to prevent the decomposition of PFA to promote the corrosion of the equipment, and the residence time at high temperature should not be too long.

Packaging, transport, storage:

1. Packaging in two layers of plastic bags, and then in the outer packaging plastic bags, each bag of 25 kg net weight, each bag with certification.

2. Store in a clean, dry, cool, light-shielded environment to prevent impurities from mixing.

3. Non-toxic, non-combustible, non-explosive, non-corrosive, transported as non-dangerous goods
