Brief introduction:
Polyester PU rod: 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.
Application:
Applicable to the metallurgical, mining, oil, automobile, building materials, sports, heavy machinery, large stamping equipment vibration 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.Polyurethane elastomer is a new type of polymer composite materials between rubber and plastic, it has the high strength of plastic and has a high elasticity of rubbe

Specification
Its characteristics are:
1, wide range of hardness.It still has the rubber elongation under high hardness and resilience.Polyurethane elastomer hardness in the range of shaw A10 - D80.
2, high strength.Under the rubber hardness they break strength and bearing capacity is higher than general rubber.Under the high hardness, the impact strength and bending strength is much higher than plastic.
3, wear-resisting.Its wear resistance is very outstanding, generally in 0.01 0.10 cm (after) / 1.61 km range, about 3 to 5 times of the rubber.
4, oil resistant.Polyurethane elastomer is a kind of strong polar polymer compound, and nonpolar mineral oil affinity is small, almost not affected by erosion in the fuel oil and machine oil.
5, oxygen and ozone resistance is good.
6, the vibration absorption performance is good, can do vibration, cushion.In mould manufacturing, instead of rubber and spring.
7, good low temperature performance.
8 and radiation resistance.Polyurethane high-energy radiation resistant performance is good, in 10-10's radiation doses still has a satisfactory performance.
9, has a good mechanical processing performance.(cars, milling, grinding, drilling)
