Discrimination Method of UHMWPE

UHMWPE Production Process is a sophisticated process. UHMWPE technology is widely used in industry. Do you know the Discrimination Method of UHMWPE?

Ultra-high molecular weight polyethylene is a polymer compound, it is difficult to process, and has superior wear resistance, self-lubricating, high strength, chemical stability, anti-aging properties, so in the identification of true and false polymer poly Ethylene, we must pay attention to these several features of it, the specific identification method is as follows:

1. Weighing rules: pure UHMWPE products made of the proportion between 0.93-0.95, the density of smaller, can float on the water. If it is not pure polyethylene, it will sink to the bottom.

2. Temperature measurement: pure UHMWPE products, will not melt at 200 degrees Celsius, will not be deformed, but will become soft. If it is not pure UHMW polyethylene material will be deformed at 200 degrees Celsius.

3. Visual method: The real ultra-high molecular weight polyethylene surface smooth, uniform, smooth and cross-section density is very uniform, if not pure polyethylene material color dull and uneven density.

4. Edge test method: pure ultra-high molecular weight polyethylene flanging rounded, uniform, smooth, if not pure polyethylene flanging end face cracks, and flanging when heating will appear dregs phenomenon.
