Summary:Dec 05,2020

High-density polyethylene (HDPE) is a white powder or granular product. It is non-toxic, tasteless, crystallinity is 80%-90%, softening point is 125-135℃, service temperature can reach 100℃; hardness, tensile strength and creep are better than low-density polyethylene; wear resistance, electricity Good insulation, toughness and cold resistance; good chemical stability, insoluble in any organic solvents at room temperature, resistant to corrosion by acids, alkalis and various salts; the film has low permeability to water vapor and air, and water absorption Low; poor aging resistance, environmental stress cracking resistance is not as good as low-density polyethylene, especially thermal oxidation will reduce its performance, so antioxidants and ultraviolet absorbers must be added to the resin to improve this deficiency.

 

High-density polyethylene is usually manufactured by Ziegler-Natta polymerization method, which is characterized by no branches on the molecular chain, so the molecular chain is arranged regularly and has a higher density. The process uses ethylene as a raw material in a tubular or kettle-type low-pressure reactor and uses oxygen or organic peroxide as an initiator to initiate the polymerization reaction.

 

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