Polyurethanes resin embodies the properties of foam, rubber, thermoplastic plastics as well as thermoset plastics, it can be used as elastomers, adhesives and coating etc and can also be adopted as synthetic fiber of large shrinkage. The substance is of high elasticity, obdurability and tensile strength, and can fight against the erosion from oil or solvent and can resist aging and abrasion.
It will decompose in water and can not resist against acid, alkali, boiled water and vapor.
Application:
1) As foam, Due to it’s properties such as high elasticity, tensile strength and fatigue resistance, the substance can be used as soft foam.
2) As rubber elastomer. The substance is of sound elasticity, tensile strength, rupture strength, abrasion resistance as well as age resistance and can be used as tires for trucks, various rollers or conveying belts and quiet gears.
3) As coating and adhesive. Coating and adhesives made from polyurethanes resin can be well adhered to the adhesive interface and can be used to adhere such material as wood, rubber, glass and metals. It will turn yellow under ultraviolet radiation
