Eight Points to Determine the Quality of High Molecular Weight Polyethylene Sheets

With the widespread use of high molecular weight polyethylene sheets, this product has gradually gained recognition from users. At the same time, there are more and more manufacturers producing these sheets, so users need to have the ability to distinguish product quality when purchasing. Today, we will teach you a few simple methods to identify product quality.

1. First, observe the surface gloss of the sheet. Poor gloss indicates recycled plastic.

2. Check the toughness of the high molecular weight polyethylene sheet. Sheets made from pure PP (polypropylene) plastic are highly tough and slightly bendable.

3. Transparency: recycled plastic has poor transparency.

4. Toughness: recycled plastic is also much poorer in toughness.

5. Density: throw it in water to see if it floats. Most recycled plastics sink.

6. Examine the cut surface. Recycled plastic will have different colored impurities inside after cutting.

7. Check its density. The density of PP (polypropylene) is 0.92~0.93; those that float on water are made from raw polypropylene.

8. Heat welding: recycled plastic produces smoke during welding.
