outline:
AdoptEPDM(EPDM) as raw materials, smooth and meticulous surface, good resilience, uniform foaming, first-class waterproof performance, anti-ozone, aging resistance, solvent resistance are good. EPDM foaming products: 1. polyethylene open-cell foam rubber expansion joint board (caulking board. caulking board) (I) product characteristics ▲ Light bulk density, large telescopic strength, non-absorbent (replacing traditional three-oil four felt, asphalt wood fir board and other materials). Product environmental protection, simple construction, anti-seepage, anti-leakage, good water effect. ▲ Corrosion resistance, aging resistance, high and low temperature 80 ℃ ~-45 ℃, no flow, no deformation, no embrittlement, long service life. ▲ With independent opening bubble structure, special joint plate appearance is honeycomb holeuniform distribution, it can be used with cement/SealantClose bonding and integration, adapt to the change of natural expansion and contraction, and enhance the sealing effect of joint expansion and water stop. Application range of (II) products Can be widely used in machinery, doors and windows, curtain walls, rivers, dams, ports, docks, undergroundChung HoleWater conservancy and electric power, airports, bridges and other concrete sealing joint projects. (III) product usage During construction, this product can be used in a variety of ways according to the situation. Longitudinal water-stop joints, horizontal water-stop joints and other special joints are used.
