Water Proofing and Insulation Composite Tape
Water Proofing and Insulation Composite Tape
Water proofing Tape is a kind of waterproof, sealing and insulating composite mastics with strong adhesion and shape variable. It is composed of ethylene-propylene rubber and butyl rubber. It has great self-adhesiveness, and excellent water proofing and insulation function. Easy to install, non-corrosive to copper, aluminum and cable sheathing materials. Rated service temperature is 90℃, short time overload temperature over 130℃, which can be used for insulation, waterproof, sealing and protection at power cable accessories, communication base stations, and communication cable connectors.
Product Features ￭ Excellent adhesive and waterproof function, easy to install; ￭ Excellent weather resistance and sealing function; ￭ Superior low and high temperature stability, cater for installation under various climate; ￭ Sound abrasion resistance and tensile elongation
