UHMWPE identification method

Ultra-high molecular weight polyethylene is a kind of polymer compound, which is difficult to process, and has super wear resistance, self-lubrication, relatively high strength, stable chemical properties, and strong anti-aging performance. When using ethylene, we must pay attention to its characteristics. The specific identification methods are as follows:
1. Weighing rule: The specific gravity of the product made of pure ultra-high molecular weight polyethylene is between 0.93-0.95, the density is small, and it can float on the water. If it is not pure polyethylene material, it will sink to the bottom of the water.
2. Visual method: The real ultra-high molecular weight polyethylene has a flat, uniform, smooth surface and a very uniform cross-sectional density. If it is not pure polyethylene, the color is dull and the density is uneven.
3. Edge test method: The pure ultra-high molecular weight polyethylene flanging end face is round, uniform and smooth. If it is not a pure polyethylene material, the flanging end face has cracks, and slag will appear when the flanging is heated.
