Although the molecular structure of UHMWPE is the same as that of ordinary polyethylene, it has many excellent properties that ordinary polyethylene does not have because of its very high relative molecular weight. Like: Superior wear resistance, Low friction coefficient, Non-toxic and odorless, Surface non-adhesion, no scaling, Low temperature resistance, Chemical resistance.

Ultrahigh molecular weight polyethylene has the Wear Resistance Performance about 27 times higher than the stainless steel. Even in harsh environment, UHMWPE parts still can move freely, ensuring that the relevant workpiece will not be worn and pulled. Because of its small friction coefficient and non-polarity, UHMWPE has non-adherent surface properties. Ultrahigh molecular weight polyethylene tube can be stored between -269℃ and 80℃ for a long time. Because the unsaturated molecules in the molecular chain are few and the stability is high, the aging rate is particularly slow. Ultrahigh molecular weight polyethylene (UHMWPE) has excellent chemical resistance, and many corrosive media and organic solvents are also helpless to it in a certain range of temperature and concentration.

Seeking higher tensile strength is always the target of surgical sutures. The special parameter of above make UHMWPE become the ideal material of orthopedic sutures. The knot pull tensile strength even higher than polyester that developed different sutures kit for the tendon repair and replacement, which including Elbow, Hand Wrist and others, especially for small animals. It was braided in White-Blue, White-Green and other different combination on colors to offer a convenient visibility during the complicated surgery. To make the thread soft and easy to handle, some company braided together with long chain polyester fiber as jacket that provide a better handle performance. To keep force with less trauma, tape shape was introduced as part of the kit. These kit need special trained on the veterinary surgeon that to ensure the positive result. By introducing these, the pets’ life was treated better.
