Insulating material for wires and cables


70 ℃ -90 ℃ PVC insulation / sheathing material for wire and cable
Product description
The ordinary 70 ℃ -90 ℃ insulation and sheath materials developed by Zibo Qiwangke Industry and Trade Co., Ltd. are based on high-quality Qilu PVC resin, and add appropriate amounts of plasticizers, lubricants, stabilizers and other processing aids. The plastic granules obtained by mixing and extrusion granulation have excellent physical and mechanical properties, insulation and dielectric properties, and good processing properties.
The cables processed with this product can meet the requirements of users, and can be widely used in subways, airports, power stations, high-rise buildings, computer centers, television centers and other places that require high cable requirements.

Appropriate processing technology
The PVC insulation / sheathing material produced by our company has good processing performance, there are no special requirements for extrusion equipment, and it can be processed by ordinary PVC cable extruder. The process conditions can be based on the extrusion process of ordinary PVC cable material. The applicable process temperature range is wide, has excellent processing stability, and the formed cable has good appearance and insulation properties. The recommended process temperatures are as follows:
