Product Description
Polyethylene (PE) is one of the most popular thermoplastic materials. It is available in different crystal structures called HDPE, LDPE and LLDPE.This commercial plastic is produced by addition or free radical polymerization. It is used in a wide range of applications: plastic containers, bottles, bags, plastic toys, etc.
What is PE?
Polyethylene or polyethylene is a type of polyolefin. It is often abbreviated as PE. The chemical formula for PE is (C2H4)n. It is lightweight, durable, and one of the most commonly used plastics. It is used in frozen food bags, bottles, cereal liners, yogurt containers, and more. Looking around, all plastics with recycling codes 2 and 4 are made from PE. These plastics have different crystal formations
How is PE made?
Polyethylene is produced by the polymerization of ethylene (or vinyl) monomers.PE chains are produced by addition or free radical polymerization. Possible methods of synthesis are:
Ziegler-Natta polymerization and metallocene-catalyzed
What are the common types of PE?
Depending on their density and branching, different PE grades may have very different properties. Therefore, PE grades are categorized as follows.
Branching Versions
Low Density Polyethylene
Linear Low Density Polyethylene (LLDPE)
Linear version
High Density Polyethylene
Ultra High Molecular Weight Polyethylene
Cross-linked polyethylene (PEX or cross-linked polyethylene)
