Polyethylene is the world's most widely used thermoplastic and is made by the polymerization of ethylene. Polyethylene is often classified by its density, because greater density corresponds with greater material rigidity. The world�¢??s largest volume polyethylene is high density polyethylene (HDPE), which has a relatively high degree of tensile strength. Plastic containers represent the most common household use of high-density polyethylene. At the opposite end of the spectrum is low density polyethylene (LDPE), which was the first type of polyethylene to be developed. Flexible packaging represents the most common household use of low-density polyethylene. Both high- density polyethylene and low-density polyethylene are also commonly used for moulding applications. Linear low-density polyethylene (LLDPE) can usually be manufactured at a slightly lower cost than low density polyethylene and has similar basic properties. While low-density polyethylene and linear low-density polyethylene are to a certain extent substitutable for each other, one may be more suitable than the other for a specific application.
Ethylene Vinyl Acetate (EVA) is a copolymer, which means it is a type of plastic that is made up of two different monomers or building blocks: ethylene and vinyl acetate. Copolymers like EVA are created by polymerizing these two monomers together, resulting in a material with a combination of properties derived from each component. Sipchem EVA 3522 CO is a 22% ethylene vinyl acetate copolymer resin, manufactured by IPC an affiliate of Sipchem in The Kingdom of Saudi Arabia using an Exxon-Mobil high-pressure tubular process. EVA 3522 CO is designed for specialty extrusion and compounding applications. Articles made from EVA 3522 CO are soft and have excellent low temperature toughness.
Linear low-density polyethylene (LLDPE) is a substantially linear polymer polyethylene with significant numbers of short branches, commonly made by copolymerization of ethylene with longer-chain olefins. Applications: It is used for plastic bags and sheets, plastic wrap, stretch wrap, pouches, toys, covers, lids, pipes, buckets and containers, covering of cables, geomembranes, and mainly flexible tubing.
