Buyers How To Identify The Authenticity Of Ultra-High Molecular Weight Polyethylene Sheet
For the ultra-high molecular weight polyethylene plate and other related sheet products have applications of users know that it is a polymer compounds, with super wear resistance, self-lubricating, high strength, chemical stability, anti-aging properties, so in order to buy the product for the ultra-high molecular weight polyethylene plate authenticity should be how to identify it?
1. Weighing law: the specific gravity of the real UHMWPE sheet products between 0.93-0.95, less dense, can float in the water. If it is not pure polyethylene material, it will sink to the bottom of the water.
2. Temperature Measurement: It will not melt at 200 degrees Celsius and will not be deformed, but will become soft. If it is not pure polythene, it will be deformed at 200 degrees Celsius.
3. Visual method: the surface of the real UHMWPE sheet is flat, even, smooth, black and shiny and the density of the cut surface is very uniform, if it is not pure polyethylene material, the colour is dull and the density is not uniform.
4. Edge test method: pure UHMWPE flanging end face is rounded, even and smooth, if not pure polyethylene material flanging end face has cracks, and there will be slagging phenomenon when flanging after heating.
