II.   Product description

Low-smoke, low-halogen and flame retardantPVC compound for cables and wires, based on PVC resin, is made into granula byspecial technology with adding special plasticizer, stabilizing agent, flameretardant, smoke suppressant, HCL absorber and other special agents. Thecompound has well performance of flame retardant. It has low smoke and lowburst size of HCL when burning. The produced wires and cables have 60% lighttransmittance. The products meet various special requirements, UV stable,environment friend (RoHs, REACH, PAHs, chlorinated alkanes free,  phthalate free, and etc.), sub-shine and fogsurface, rodent-repellent, termite-repellent, and etc.

III.  Processing

It is recommended that compound should beprocessed with common extruder having a minimum L/D ratio of 20. Non-specialrequirements of equipment and processing are needed.

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