Polyurethane wheels are widely used in daily life and industrial production. Due to its unique advantages, it brings great convenience to our production and life. Next, let’s learn more about polyurethane wheels.
I. Characteristics of polyurethane wheel
Polyurethane elastomer has the high elasticity of rubber and the high hardness and strength of plastic. It has excellent abrasion resistance, high mechanical strength, and excellent oil resistance, chemical resistance, flex resistance and low temperature resistance. Polyurethane wheels have low rolling resistance; abrasion resistance is increased by several times for a long service life; the tread material is free of carbon black and rubber-filled oils, and does not contaminate the air and soil when worn. Polyurethane elastomer is the ideal material for green tires and green manufacturing of tires. Polyurethane casters have good load-bearing capacity, wear resistance, corrosion resistance and shock resistance. They are considered to be the first choice among caster materials. Generally, industrial casters are available in sizes ranging from 4 to 8 inches (100-200 mm). As far as materials are concerned, polyurethane wheels are the best, with excellent abrasion resistance, a wide range of adjustable properties, a variety of processing methods, wide applicability, oil and water resistance. Ozone resistance, aging resistance, radiation resistance, low temperature resistance, good sound transmission, strong adhesion, excellent biocompatibility and blood compatibility.
2、Application fields of polyurethane casters
Polyurethane casters are significantly better than wheels made of other materials in terms of wear resistance, caster rolling resistance and tear resistance. The load bearing capacity of polyurethane casters of the same size is 6-7 times higher than that of rubber wheels. The production process can be continuous and automated, and very little waste is generated during production and use. What’s more, part of the carcass of the used polyurethane casters can be recycled for use as other polyurethane products without causing environmental pollution. Moreover, it adopts liquid casting molding, and the manufacturing process is simple. Therefore, it is called the green caster of the 21st century. Polyurethane wheel will be the mainstream of the future development of casters in various industries, polyurethane universal wheel in the automotive industry has a broad application prospects.
