Silicone rubber fiberglass sleeving (English name: Silicone rubber fiberglass sleeving), also known as fire-resistant sleeving, high-temperature resistant sleeving, is made of high-purity alkali-free glass fiber woven into a tube, and then coated with organic silica gel on the outer wall of the tube after vulcanization treatment. to make. After vulcanization, it can be used for a long time in the temperature range of -65°C-260°C and maintain its soft and elastic properties.
PVC polyvinyl chloride (hereinafter referred to as PVC) insulation material is a mixture of stabilizers, plasticizers, flame retardants, lubricants and other additives added to PVC powder. According to the different application and different characteristics of the wire and cable, the formula is adjusted accordingly.
Flame-retardant: PVC casing self-extinguishes away from the fire (it will self-extinguish within 30 seconds after the flame is separated), the flame will not spread along the pipeline.
This material is particularly important in cable applications. Most of the wrapping cable insulation materials use PTFE, why always choose this material? The following is known by understanding the performance of this material.
