Environmental impact polyethylene Performance
Polyethylene water, high humidity or physical properties of the water change. Concentrated sulfuric acid, concentrated nitric acid and other oxidants will slowly erode polyethylene. In aliphatic hydrocarbons, aromatic hydrocarbons and chlorinated hydrocarbons, polyethylene swelling phenomenon will occur, but the volatile swelling agent can restore the original performance. Below 60 ℃, polyethylene ability of most solvents, but the temperature is higher than 70 ℃ hydrocarbon solvents will quickly erode polyethylene. When the temperature continues to rise, polyethylene dissolves in certain solvents. Separated from the solution of the polyethylene to form a paste or gel state depending on the temperature after cooling.
