Machinery used in foam rubber seal Brief: EPDM as raw material, the surface smooth and detailed, good elasticity, good foam evenly, waterproof performance of first-class, anti-ozone, anti-aging, solvent resistance are good. (A) Product Characteristics ▲ light weight, high strength stretching, does not absorb water (instead of the traditional three oil four felt, bituminous cedar wood plates and other materials). Product environmental protection, simple construction, seepage, leakage, good sealing effect. ▲ corrosion resistance, aging resistance, high temperature + 80 ℃ ~ -45 ℃ not flowing, no distortion, no embrittlement, long service life. ▲ independent opening bubble structure, a special type of joint appearance of the honeycomb plate holes evenly distributed, do not fight hair to the cement / adhesive sealant closely integrated, adapt to the natural expansion and contraction change, enhance joint sealing expansion of the sealing effect. (B) construction of the product according to the situation using a variety of methods can use the product to use. Longitudinal sealing seam sealing horizontal joints and other special joint use. Cui category brand foam (sponge) rubber sheet series single EPDM material extruded rubber mounting adhesive caulk or microwave curing production process structure EPDM sponge rubber gel content of 30% -40% (A grade) 20 % -30% (B grade) life of 20 years Specifications plans to sample custom processing origin Hebei Qinghe (Cui Rubber Products Co., Ltd.) use can be widely used in machinery, doors, windows, walls, rivers, dams, ports and terminals underground Chung-dong, water power, airports, bridges and other concrete joint sealing project.
