Anti-aging, durability, and adapt to the ambient temperature range and high resistance to puncture strength, friction coefficient, corrosion, acid, non-toxic characteristics, can be -60 ℃ ~ 60 ℃ under the conditions used in the cover up using more than 50 years, construction convenient, reliable and effective. Widely used in reservoirs, dams, channels, reservoirs, diversion tunnel, water recreation facilities, roads, airports, buildings, water and various grass-roots underground, underwater works as anti-leak liner and the landfill company, wastewater treatment plant and other environmental protection projects. Water board is the tunnel, dam waterproofing material of choice. EVA, ECB board is waterproof ethylene - vinyl acetate copolymer adding special additives and anti-aging agent, by the Sec rolling out the production of three-roll sheet. Have excellent weather resistance, low temperature resistance, flexibility, elongation, anti-penetration performance. Railway, subway, water, tunnels, highways, waterproofing and drainage works, dam protection works, roofing, seepage, landfill, port construction.
