Product Description
Polyurethane (PUR and PU) is a polymer composed of a chain of organic units joined by carbamate (urethane) links. While most polyurethanes are thermosetting polymers that do not melt when heated, thermoplastic polyurethanes are also available.
Polyurethane polymers are traditionally and most commonly formed by reacting a di- or polyisocyanate with a polyol. Both the isocyanates and polyols used to make polyurethanes contain on average two or more functional groups per molecule.

PU sheet/rod: thermosetting Polyurethane elastomer referred to as "PU, English name Casting Polyurethane, commonly known as optimal force glue, rubber spring, is made up of polymer polyols and isocyanates reaction, chain extender chain to pay, a new synthetic material between plastic and rubber.According to the main chain of the polyurethane elastomer structure is different, divided into two kinds of polyether and polyester.Polyether type of polyurethane: English name Polyether urethane.Polyether type of polyurethane occupies the main status in the polyurethane, mainly because of polyether viscosity is small, easy to operate.Polyether resilience, moisture evaporation, low temperature performance, the impact strength, heat accumulation, water resistance, resistance to mildew is better than polyester.Polyester polyurethane: English name Polyester polyurethane, compared with polyether, mechanical strength, tensile strength, tear strength, sliding friction, oil resistance, thermal aging, to metal adhesion, solvent resistance and oxidation resistance of polyether type.But the polyester viscosity, more difficult to operate.Product features: polyurethane elastomer with resistance to chemical corrosion resistance, tensile strength, high elasticity, high pressure load, strong resistance to abrasion high strength, shock absorption, tear resistance, radiation resistance, high strength, high load and shock absorption, etc. Good performance.In a wide range of hardness (A10 shaw to shao D75) can keep the high elasticity.Unique their excellent comprehensive performance is common plastic and rubber.Areas of application: applicable to the metallurgical, mining, oil, automobile, building materials, sports, heavy machinery, large stamping equipment damping plate, block, spring, and to do all kinds of metal plate, pipe punching die.General machinery and equipment of the friction, buffer or shock absorption effect, is the ideal die springs.
Specification: thickness (2-200 - mm) * 500 mm * 500 mm wide
(2-200 - mm) * 300 mm * 300 mm wide
Great thick (2-200 - mm) * 300 mm / 1000 mm long
