Plastic castor light and cheap chemical stability impact resistance

An overview, plastic castor plastic for synthesis of high molecular compound { Polymer ( 聚合物) And what might be called a polymer or macromolecules ( 大分子) It is also the plastic (commonly known as the general 塑料) Or resin ( resin) , feel free to change form style. Raw materials in synthesis or condensation reaction is the use of monomer polymerization material, by the synthetic resin and packing, plasticizer, stabilizer, lubricants, pigment and other additives. Two advantages, plastic castor light weight and strong resistance to chemical erosion easy processing can be mass production, much cheaper for insulation plastic light, good chemical stability, not good corrosion resistance to impact the parameters of the three, plastic castor type bearing bearing type flexible floor protection range rotation peaceful resistance to high temperature and low temperature resistant plastic castor wheel core - 20 400 light - powered mechanical optimal poor poor superior polyolefin or nylon/news_71 commonly.
