What is PU wheel? What are the characteristics of PU wheel?
     PU wheel commonly known as Youli glue, spring glue, full name: polyurethane or isocyanate polymer. PU wheel is a kind of elastomer between plastic and rubber. Its excellent and peculiar comprehensive properties are not possessed by ordinary plastic and rubber.

What are the characteristics of PU wheel?   

The elastomer of PU wheel has good properties such as abrasion resistance, chemical erosion resistance, high strength, high elasticity, low pressure resistance, abrasion resistance, strong shock absorption, tear resistance, radiation resistance, high bearing capacity and shock absorption. PU wheel also has a wide hardness scale, from shore a10-100.

At present, there are products that surpass Shaw's A100 and above on the market. In addition, PU wheel has excellent shock absorption performance, can shock absorption cushion plate, impact resistance than metal spring, does not damage the mold. These characteristics of PU wheel are very suitable for caster material.

Processing method of PU wheel
     PU wheel elastomer can be molded by plasticizing, mixing and vulcanizing process like general rubber (MPU); PU wheel can also be made into liquid rubber, casting molding or spraying, pouring, centrifugal molding (refers to CPU); The PU wheel can also be made into granular material, which can be molded by injection, extrusion, calendering, blow molding and other processes like ordinary plastics. Molding or injection molding parts, in a certain hardness scale, can also be cutting, grinding, drilling and other mechanical processing. Due to the diversity of processing, the applicability of PU elastomer is very common, and its application scope has been expanding.

Detailed application of PU wheel materials
     

PU wheel is not only a very good caster, but also a kind of flexible PU cushion material, such as high chair, sofa, mattress, etc；

Sound absorption materials: the polyurethane foam with holes has good sound absorption and shock absorption function, which can be used as indoor sound insulation materials to effectively reduce indoor music;

Fabric composite materials - shoulder pads, bra sponges, make-up cotton; Toys, etc；

PU Rigid PU；

PU wheel rigid foam refrigeration equipment, such as refrigerator, freezer, cold storage, refrigerated house, etc., polyurethane rigid foam is the most imaginative heat insulation material of refrigeration equipment, which is widely used.
