The Characteristics and Application of Polyurethane Casters
1. The Characteristics of Polyurethane Casters
Polyurethane elastomer not only has the high elasticity of rubber, but also has the high hardness and high strength of plastic. It has excellent wear resistance, high mechanical strength and excellent oil resistance, chemical resistance, flex resistance and low temperature resistance. Polyurethane casters have low rolling resistance; wear resistance is improved several times, and the service life is long; the tread material does not contain carbon black and rubber filling oil, and will not pollute the air and soil after wear. Polyurethane elastomer is an ideal material for green tire manufacturing and green tire manufacturing.
2. The Application Field of Polyurethane Casters
Polyurethane casters are significantly better than casters made of other materials in terms of abrasion resistance, rolling resistance and tear resistance. The load-bearing capacity of polyurethane casters of the same size is 6-7 times that of rubber wheels. The production process can be continuous and automated, and the waste generated during production and use is very small.
More importantly, part of the carcass of waste polyurethane casters can be recycled and used as other polyurethane products without causing environmental pollution. Moreover, it is formed by liquid casting, and the manufacturing process is simple. It is called the green casting machine of the 21st century. Polyurethane casters will be the mainstream of caster development in various industries in the future, and polyurethane casters have broad application prospects in the automotive industry.
