Description and Application 產品描述和用途
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是一種低煙無鹵阻燃熱塑性彈性體，其具有優良的物理機械性能，電性能，阻燃性能以及加工性能，更為突出的是其具有卓越的耐高溫老化性能，特別適用于對老化條件要求較高的絕緣，護套上，也可用于其它有較長使用壽命要求的電纜上。產品無需交聯，加工工藝簡單，環�？苫厥�。最高使用溫度為125℃。
