Description and Application 产品描述和用途
TEWR125 is a kind of thermoplastic low-smoke halogen-free flame-retardant elastomeric compounds. The highest working temperature is 125℃. It has good mechanical property, electrical property, flame retardant property as well as processability. Its high-temperature resistant aging property is very well and suitable for strict aging requirements of insulation and jacketing. It also can be used for other cables which have long service life requirements. It is simple processing without cross-linking and can be recycled.
