PVC cable materials with special features are materials, which have features such as rodent, termite, oil resistance, anti-migration and anti-ultraviolet. Such materials are PVC-based cable materials, which is produced by mixing and granulating with accessory ingredients such as plasticizers, special additives, fillers, stabilizers and lubricants.
