Application  and Cable Specification

3901N

PVC insulating compound for VDE standard  at 90℃

Used for wires and cables which according  with VDE standard

3921N

PVC jacket compound for VDE standard at 90℃

Used for wires and cables which according  with VDE standard

II.    Productdescription

PVC compound for VDE standard wires andcables, based on PVC resin, is made into granula by mixing, plastification andgranulation with adding plasticizer, stabilizing agent, flame retardant andetc. The products meet various special requirements, such as differenthardness, UV stable, environment friend (RoHs, REACH, PAHs, chlorinated alkanesfree,  phthalate free, and etc.),sub-shine and fog surface, low temperature resistant, PS/ABS transfer proof,rodent-repellent, termite-repellent, and transparent, and etc.

III.  Processing

It is recommended that compound should beprocessed with common extruder having a minimum L/D ratio of 20.

The following temperature(℃)profile of extruder is recommended:
