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.
TEWR125是一种低烟无卤阻燃热塑性弹性体,其具有优良的物理机械性能,电性能,阻燃性能以及加工性能,更为突出的是其具有卓越的耐高温老化性能,特别适用于对老化条件要求较高的绝缘,护套上,也可用于其它有较长使用寿命要求的电缆上。产品无需交联,加工工艺简单,环保可回收。最高使用温度为125℃。
