The application of UHMWPE

The molecular chain length of UHMWPE is 10 ~ 20 times that of hdpe. The main advantages of longer molecular chains (higher molecular weight) give UHMWPE are toughness, wear resistance and resistance to stress cracking. Because it is a kind of polyethylene, UHMWPE also has lubricity, chemical resistance and general purpose HDPE excellent electrical properties.
Long molecular chains make materials difficult to process in common moulding and extrusion equipment. When heated above the melting point, UHMWPE becomes transparent but does not flow.Chemical and performance UHMWPE is produced by ziegler polymerization. The process requires a particularly high degree of purity, ethylene monomer impurity control in a few parts per million. The product is a white powder with a particle size similar to that of table salt.
UHMWPE is used for low speed bearing housing. Low friction coefficient is further reduced by adding siloxane, aluminum disulfide, graphite and special paraffin wax. In the food processing industry, UHMWPE self-lubricity, easy purification, low flavor gas/flavor transmission and boiling water resistance are used. Has met FDA and USDA requirements for use in food, water, and pharmaceutical industries. Some of the USES of UHMWPE are based on its noise absorption and shock absorption. If UHMWPE is needed, dye can be used for coloring, while pigments are slightly inferior.  PTFE/Polymer/UHMWPE Tube Ram Extruder，  PTFE/Polymer/UHMWPE Rad Ram Extruder,  Gasket machine, Plastic Pipe machine, etc. These machines can be used to produce a variety of fields need some ptfe, polymer, ultra high molecular weight and other products.
UHMWPE may be used in a new generation of self-unloading ore carriers, railway wagons and large trucks due to its smooth, non-viscous and abrasion resistance. These properties make it also useful for agriculture and earth-moving machinery, with UHMWPE materials to protect steel. The combination of chemical resistance and surface smoothness has many applications. For food processing industry, UHMWPE is used as the surface material of meat cutting board. UHMWPE is used as contact surface and roller for processing food and medicine conveyors. It has the properties of self-lubricating, resistance to boiling water and resistance to chemical cleaner.
