Description

Application in cable compounds

A. HFFR cable compounds

ATH/(AL(OH)& MDH/Mg(OH)wildly used as flame retardant in HFFR/LSZH cable compounds, due to a big addition(usually 55-70%), the flow of resin and  processing will be deteriorated, frication between the fillers generate heat may cause the decompose of ATH(150℃) and instability during extrusion,  and the poor dispersity of flame retardant fillers will  cause defects on the  surface of cable. A small dosage of silicone masterbatche can significantly improves processing, flow, surface, and mechanical properties, reduce deposits on the die and in the extruder and flame-retardant properties are synergistically improved

B. Application in Silane cross-linked cable compound

The linear structure of LLDPE will turn into net structure after Silane-grafting and cross-linking reaction, in this way the flow of resin become bad, the compounds are easily adhere to screw groove and mold dead corners and formdead mass which will affect the extruded cable appearance ( rough surface with little pre-crosslinking particles which formed at cross-linking step ) so we need a kinds of lubricant to improve the flow of resin and processing.

C.Application in Low smoke PVC cable compounds

High content of flame retandant fillers (ATH&MDH), the flow of resin and processing will be deteriorated, frication between the fillers generate heat which will increase the temperature and cause the decompose of ATH & PVC and unstable during extrusion, and the poor dispersibility of flame retardant fillers will cause defects on the surface of cable. A small dosage of silicone masterbatche can significantly improves processing, flow, surface, and mechanical properties, reduce deposits on the die and in the extruder and flame-retardant properties are synergistically improved

D. Application in TPE wire 

For good quality TPE wire have a high requirement on the surface quality especially nice hand feeling, and its a kind of fine wire and the pay-off speed is very fast, so the wire will suffer a big shear force at the extruder die which will easily cause melt fracture a small dosage of silicone masterbatch will improve the flow of resin and processing highier the pay-off speed, offer a nice hand feeling and  its non-migration.
