Product Description

Rubber water-stop tape (strip) is made of natural rubber and synthetic rubber as main raw material, mixed with various additives and fillers, mastication, mixing, molding, more varieties and specifications. Rubber water stop with good flexibility, abrasion resistance, aging resistance and tear resistance, adapt when temperature exceeds 70 C, well rubber water-stop by strong oxidation ability deformation, waterproof, temperature range from -45 C to +60 C erosion role or by the oil and other organic solvents, are not allowed to use rubber water stop.
Based on usage can classified as buried in the rubber water stop and back paste-type rubber water stop (outside - attached rubber water stop), steel side rubber water stop, water swelling rubber water-stop Flatbed water-stops.

Externally bonded type water-stops or back-paste style water-stops, no externally bonded type intermediate pass water-stops, back paste type water-stops main (concrete water face) apply to outside concrete structures backplane or siding. Mainly used in the practical application of structures triggered sewn entirely contraction joint, incomplete contraction joints and other parts. With concrete anchoring close, sealing sealing and elastic tensile deformation characteristics, water-stop system and adoption of a flexible material, and mixed with a variety of adjuvants made by mixing, curing. According different material selection can be divided into water-stops natural rubber, chloroprene rubber (CR)water stop, nitrile rubber (NBR)water-stops, EPDM rubber water stop.
