Does PE physical foam material have chemical pollution? (physical foam gasket)

PE, that is, polyethylene, has a chemical formula of nCH2. It can be seen from the chemical formula that the material only contains stable carbon and hydrogen elements, and the chemical effects are very stable. PE products are called pollution-free products by advanced countries in the world. During the production process of the products, they will not cause environmental pollution. After the products are used, they are easy to recycle and have non-toxic, odorless, drug-resistant, oil-resistant, acid-resistant, halogen-resistant and other properties.

What environment is the silicone gasket not suitable for (physical foam gasket)

What environment is the silicone gasket not suitable for (physical foam gasket)

There are many advantages of silicone gaskets. First, its heat resistance can work in a very low temperature environment, the lowest can reach minus 100 degrees. It has good resistance to oxidation and ozone in the air, because the molecules of silicone The structure makes the silicone sealing ring have good air permeability and good selectivity to gas, and because it is non-toxic and tasteless, silicone sealing gaskets are used in many food and medical industries.
