Plastic Raw Material Chemical PE CAS 9002-88-4 Polyethylene HDPE

Product Description

HDPE is a highly crystalline, non-polar thermoplastic resin. High-density polyethylene is a white powder granular product, non-toxic and odorless, with a density in the range of 0.940~0.976 g/cm3; a crystallinity of 80%~90%, a softening point of 125~135°C, and a service temperature of up to 100 ºC; melting temperature is 120~160ºC. For materials with larger molecules, the recommended melting temperature range is between 200~250ºC. It has good heat resistance and cold resistance, good chemical stability, high rigidity and toughness, and good mechanical strength. The dielectric properties and environmental stress cracking resistance are also good. The hardness, tensile strength and creep properties are better than low-density polyethylene; the wear resistance, electrical insulation, toughness and cold resistance are all better, but slightly worse than low-density insulation; the chemical stability is good, at room temperature Under certain conditions, it is insoluble in any organic solvent and resistant to corrosion by acids, alkalis and various salts; the film has low permeability to water vapor and air and low water absorption; poor aging resistance

 

High-density vinyl is an environmentally friendly material that can be recycled and reused when heated to its melting point. It should be noted that plastic raw materials can be divided into two major categories: "Thermoplastic" and "Thermosetting plastic". "Thermosetting plastic" becomes a solidified state after being heated to a certain temperature. Even if it is continued to be heated, it cannot change its state. Therefore, products with environmental issues are "thermosetting plastic" products (such as tires), not "thermoplastic plastic" products (such as plastic pallets Note: pallets are called "plywood" in Hong Kong and Macao), so not all " Plastic is not environmentally friendly
