70 Degree Insulation Grade Flexible PVC Plastic
Notes:
Far East New Materials’ 70 Degree flexible PVC cable insulating compound (J-70) refers to insulating material for wire and cable. It is produced from PVC as base material and auxiliary materials, such as plasticizer and stabilizer, after being mixed, plasticized and granulated. It is applicable for insulating layer of instrument communication cable, 0.6-1KV and below cable.
