Take you to read the use of polyurethane casters & quot; Hidden rules & quot; , polyurethane casters in abrasion resistance, rolling resistance and tear resistance is superior to noon embryo; The same size of the polyurethane rubber tire caster wheel load capacity is 6 ~ 7 times. Its can achieve continuous production process and automation, produces little waste in the process of the production and use, and more importantly waste tire part of the body can be recycled for other polyurethane products, will not cause environmental pollution; Simple - and its manufacturing process - - - - - - Liquid pouring shape, belongs to the new no cord casting wheel, thus known as the 21st century green tire. Pu castor, will be the future developing trend of the automobile tires, has broad application prospects in auto industry. Polyurethane casters, it is a kind of a material between general rubber and plastic, this is by far the most resistant elastomer, and harmless to human body, and can completely biodegradable, don't need to add carbon black and some have carcinogenic effect of rubber compound, is the ideal material for manufacturing tire tread. The biggest characteristic of polyurethane casters is within the scope of the hardness of the high elasticity, good mechanical strength, oil resistance and ozone resistance, good low temperature performance. Polyurethane casters product has wear-resisting, good elasticity, impact resistance, corrosion resistance characteristics, the production of polyurethane casters use agile and convenient, durable, in different occasions with wear-resistant, impact resistance, chemical corrosion resistance, good low temperature resistance, high temperature resistant, driving wheel, protect floor, little noise quiet performance. Bearing load refers to the use manual operation in a flat on the ground is easy to move in the general bearing, at the same time is able to work for a long time in the state of security for such handling general load, the need to estimate the total weight of carrying objects beforehand, and then press the allowed weight to choose the appropriate castor. Usually occurs in only three of the four casters only force, so the total weight of the weight should be * 0 in theory. 8 for appropriate.
