EVA/ECB Sheet HOME > Products > EVA/ECB Sheet
ECB (Ethylene Copolymer Bitumen): This is a thermoplastic material made in the copolymer of ethylene series resin and bitumen and has an excellent durability, chemical resistance, etc. EVA (Ethylene Vinyl Acetate): This is a material made of VA resin containing vinyl acetate and has such an excellent elongation and flexibility that it can be mixed with other resins.
It is a thermoplastic material with good durability and mechanical strength and therefore it provides excellent resistance to concrete placing pressure and hardly shows the change of physical properties even in case of laying for long term.
It is resistant to acid, alkali or other chemicals in concrete or soil, and is highly anti-corruption, waterproof and moistureproof against sea water or underground leachate.
It can be used at the range between -30°C and ±120°C and therefore is not almost affected by change of climate and has an UV brocking effect. Its elongation percentage is over 600 %, which has great responsiveness to contraction, expansion and crack of structures.
It is made in the method of thermosetting using welding machine, which has a great bonding strength allowing you to see if the thermosetting is complete using air tester.
