High rebound sponge opening agent
Soft polyurethane (PU) is mainly a linear structure with thermoplastic, it has better stability, chemical resistance, elasticity and mechanical properties than PVC foam material, with less compression deformation. Thermal insulation, sound insulation, seismic, anti - virus performance is good. Therefore used for packaging, sound insulation, filtering materials. Hard PU plastic is light weight, sound insulation, excellent thermal insulation performance, chemical resistance, good electrical performance, easy to process, low water absorption. It is mainly used in building, automobile, aviation industry, thermal insulation structural materials. Polyurethane elastomer properties between plastic and rubber, oil resistance, wear resistance, low temperature resistance, aging resistance, high hardness, elastic. Mainly used in the shoe industry and medical industry. Polyurethane can also make adhesives, coatings, synthetic leather and so on.
