1. Product Description:
Water blocking is a commonly used water blocking material. Water blocking is common with adhesive tape material absorbent resin adhesion in two layers of polyester fiber non-woven fabric in the form. When the cable is damaged, contact with moisture absorbent resin after infiltration and water blocking in. Water absorbent resin can absorb moisture, and rapid expansion
2. Product Characteristic:
Thin thickness, high water absorbency, when encountering water rapid expansion, clearance of the cable core, vertical water blocking effect filled and has good tensile strength and thermal stability, and is not influenced by high temperature environment, the high rate water absorption material and the substrate evenly and firmly combined and in use no off powder, not sticking together, simple production process, technical performance and stability, practical strong.
