Product Description



First, it can be applied to the field of plastic runway sports venues, including basketball, volleyball, badminton and tennis courts indoor and outdoor two types.This plastic field than that of the wood floor used for a long time, and abrasion resistant, oil resistant, weather resistant elastic suitable, good shock absorption, adhesion through grassroots honest.Polyurethane rubber has excellent oil resistance, which is also used as oil resistant roller.Because of the excellent performance, it can replace the alloy in automobile industry, can be used in automobile bumper, steering wheel and vehicle for peripheral parts.Secondly, because of its low wear, high friction coefficient and low noise etc., so it made transfer device has stable speed. So the coal mine and mine belt available polyurethane rubber production, casting polyurethane rubber with high hardness can be used as mercury gear gear, has the characteristics of stable liquid transfer.In addition, it is also used with the liner and the protective layer, non metal automobile anti-skid chain and high-rise building save pipe lining; high-pressure seal and high-pressure pipe; in the shoe can reduce the cost, beautiful appearance; it can be used as aircraft thin-wall tank, oil seals, dust-proof seals; the cable street, potting material electronic components and printed circuits, shockproof rubber and can be used as a ideal, but also has a broad application in human organs and health.


The second is also used in the field of defense industry, such as aerospace system of polyurethane insulation material, has excellent bonding properties, high strength and other advantages.



Application examples:

1: for unloading in the die, the peeling rubber pad.

2: in the blanking, bending, deep drawing and forming process have been widely used.
