十一.耐火電線電纜用金雲母帶
耐火電線電纜用金雲母帶采用優質金雲母紙或合成雲母紙為基材，用玻纖佈或無碳性高聚物薄膜作單麵或雙麵為補強材料，用粘合劑粘合，經高溫勻速烘焙，經專用分切機分切而成的帶狀產品，每盤雲母帶沒有結頭，最長可達二千米，耐火金雲母帶成品為乾爽、無粘連性，且具有較強的彎曲性、柔軟性。在高速繞包時具有較高的抗張強度，是制造耐火型電線電纜最理想的首選材料
mica tape :
This tape using high-quality mica paper or synthetic mica paper as base material, fiberglass or carbon free polymer films as single or double as reinforcing layer, with adhesive, through high temperature and uniform baking, using special slitting machine to cut, each coil mica tape without joint, max longth is two thousand meters, it is softness and strong. It has a high tensile strength suitable for high speed winding , is the preferred material for making fireproof wire and cable
Packing:ID:55mm,76mm.OD:300—450mm.
