How to distinguish true and false uhmw sheet 4x8
uhmw sheet 4×8 has excellent overall performance, It is very flat on the surface, various colors can be made by us, our plastic sheets are well sold in many countries. according to different application requirements, special performance requirements can be customized.
Since the performance of uhmw sheet 4×8 is now recognized, more and more engineering uses such pipes, but high-molecular-weight polyethylene sheets are on the market. Therefore, it is very important to distinguish between true and false, and hope to give the majority of engineering. The person in charge provided some help.
Raw material: ultra high molecular weight polyethylene
method：
- Weighing rule: The product made of pure ultra-high molecular weight polyethylene has a specific gravity of 0.93-0.95, and the density is small, and it can float on the water surface. If it is not a pure polyethylene material, it will sink to the bottom.
- Temperature measurement: Pure ultra-high molecular weight polyethylene products will not melt at 200 ° C, will not deform, but will become soft. If it is not pure ultra-high molecular weight polyethylene material, it will be deformed at 200 degrees Celsius.
- Visual method: The true ultra-high molecular weight polyethylene surface is flat, uniform, smooth and the density of the cut surface is very uniform. If it is not pure polyethylene material, the color is dim and the density is uneven.
- Edge test method: The pure UHMWPE flanging end face is round, uniform and smooth. If it is not a pure polyethylene material, there will be cracks on the flanged end face, and the slag phenomenon will occur when the flanging is heated.
