Introduction of ultra high molecular weight polyethylene (UHMWPE)

UHMWPE is polyethylene with a molecular weight of more than 1 million. Thermal deformation temperature (0.46MPa)85℃, melting point 130 ~ 136℃. It is a kind of linear structure thermoplastic engineering plastics with excellent comprehensive properties. The emergence of gel spinning and plasticizing spinning has made a great breakthrough in the technology of uhmwpe.

Ultra-high molecular weight polyethylene(UHMWPE ) is a polymer compound, which is difficult to process, and has excellent wear resistance, self-lubricating properties, high strength, stable chemical properties, and strong anti-aging properties. When it comes to ethylene, be sure to pay attention to these characteristics. The specific methods are as follows:

1.Weighing law: pure ultra high molecular weight polyethylene made of the specific gravity of 0.93-0.95, the density is small, can float in the water. If it is not pure polyethylene, it will sink to the bottom.

2. Temperature measurement: pure uhmwpe products will not melt or deform at 200 ℃, but will become soft. If not pure ultra high molecular weight polyethylene material at 200 degrees Celsius will have deformation.

3. Visual method: the surface of uhmwpe is flat, even, smooth and the cut surface density is very even. If it is not pure polyethylene, the color is dim and the density is uneven
