UHMWPE is an abbreviation for ultra-high molecular weight polyethylene, and is a branched linear polyethylene with a molecular weight of more than 1.5 million. Ultra-high moleculars weight polyethylene (UHMW-PE) is a linear engineering thermoplastic engineering plastic with excellent comprehensive properties.

How to distinguish UHMWPE?

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

2. Temperature measurement: Pure ultra high molecular weight polyethylene products will not melt or deform at 200 ° C, but will become soft. If it is not a pure ultra-high molecular weight polyethylene material, it will be deformed at 200 degrees Celsius.

3. Visual method: The surface of real ultra-high molecular weight polyethylene is flat, uniform, smooth, and the density of the cut surface is very uniform. If it is not pure polyethylene, the color is dim and the density is uneven.

4. Edge test method: Pure UHMW polyethylene flanging end surface is round, uniform and smooth. If it is not pure polyethylene material, the flanging end surface has cracks, and slag will appear when flanging after heating.
