Many materials are used in decoration, among which polyethylene sheet is a popular material in recent years, and many people are not familiar with it. So what material is polyethylene sheet? How to choose polyethylene sheets? Let's take a look together!
What material is polyethylene sheet ？
Polyethylene board, also known as PE board, is a type of resin with high crystallinity. Odorless and non-toxic, it feels very similar to wax and has excellent low temperature resistance. It can be used at minus 70 to 100 degrees Celsius. Moreover, it has stable chemical properties, acid and alkali resistance, and will not dissolve in solvents at room temperature, resulting in good electrical insulation performance.
How to choose polyethylene sheets:
1. Firstly, when choosing, it is important to consider its appearance. A good polyethylene sheet, regardless of its color, will have a uniform and smooth color without any turbidity or clumping. On the contrary, if the surface is not smooth and has a sense of friction, it may be made of impure materials.
2. Secondly, when choosing polyethylene sheets, it is important to pay attention to their water absorption. Good sheets have low water absorption and will not flow or accumulate when poured onto the sheets. In addition, when selecting boards, it is important to pay attention to the manufacturer and price. Do not buy low-quality and recycled materials made of inferior products for the sake of cheap prices.
3. When selecting the board grid, it is important to consider its specific gravity. A good board has a specific gravity between 0.93 and 0.96, but due to its low density, it can float on the water surface. But if the board is impure, it is heavier and easier to sink to the bottom of the water.
4. Finally, when selecting the sheet, you can view the edges. A good board has rounded and evenly intersecting edges, while on the other hand, there are cracks on the edges, which can cause slag to fall off when heated and flipped.
