II.Productdescription

PVC insulating compound for wires andcables, based on PVC resin, is made into granula by mixing, plastification andgranulation with adding plasticizer, stabilizing agent, pigment and etc. Theproducts meet various special requirements, such as different hardness, UVstable, environment friend (RoHs, REACH, PAHs, chlorinated alkanes free,  phthalate free, and etc.), sub-shine and fogsurface, low temperature resistant, PS/ABS transfer proof, rodent-repellent,termite-repellent, and transparent, and etc.

III.Processing:

Itis recommended that compound should be processed with common extruder having aminimum L/D ratio of 20.

Thefollowing temperature(℃)profile of extruder is recommended:
