The main raw material of the common polyethylene tarpaulin on the market is polyethylene, and the reason why this material is used is mainly because it has the following characteristics:
(1) Good chemical stability, resistant to dilute nitric acid, dilute sulfuric acid and any concentration of hydrochloric acid, hydrofluoric acid, phosphoric acid, formic acid, acetic acid, ammonia, amines, hydrogen peroxide, sodium hydroxide, potassium hydroxide at room temperature Wait for the solution.
(2) Polyethylene is a typical thermoplastic, it is a flammable white powder that is odorless, tasteless and non-toxic. The molded PE resins are waxy pellets extruded and pelletized, and their appearance is milky white.
(3) The melting point is 100-130℃, and its low temperature resistance is excellent, and the lowest operating temperature can reach -100~-70℃. It can still maintain good mechanical properties at -60℃, but the use temperature is 80~110℃.
