What is the difference between ultra-high molecular weight polyethylene board and high-density polyethylene board?

What is the difference between ultra-high molecular weight polyethylene board and high molecular weight polyethylene board?

1. The English abbreviation of ultra-high molecular weight polyethylene board is UHMWPE board; the English abbreviation of high molecular weight polyethylene is HDPE, referred to as PE board;

2. The production process of ultra-high molecular weight polyethylene board is compression molding; the production process of high molecular weight polyethylene board is extrusion molding.

3. The molecular weight of ultra-high molecular weight polyethylene board is much higher than that of high molecular weight polyethylene board, generally more than 3.5 million; while the molecular weight of ordinary high molecular weight polyethylene board is only hundreds of thousands.

4. The production speed of ultra-high molecular weight polyethylene board is much slower than that of high molecular weight polyethylene board. A line of ultra-high molecular weight polyethylene board can only produce tens of meters a day, while high molecular weight polyethylene board can produce thousands of meters a day;

5. The inner and outer surfaces of ultra-high molecular weight polyethylene boards are much smoother than those of high molecular weight polyethylene boards. So it won't foul.

6. The comprehensive performance of ultra-high molecular weight polyethylene board is higher than that of high molecular weight polyethylene board. Such as high wear resistance, radiation protection, self-lubricating performance, strong corrosion resistance, impact resistance, oxidation resistance, no scaling, good flexibility, low temperature resistance, non-toxic, easy connection, light weight, and easy installation.
