Linear low-density polyethylene (LLDPE)
Linear low-density polyethylene (LLDPE) is a molecular structure formed by copolymerization of ethylene and a small amount of α-olefin on the main chain of linear ethylene with very short comonomer branches. Linear low-density polyethylene is a non-toxic, tasteless, odorless milky white particle with a density of 0.918~0.935g/cm³. Compared with LDPE, it has higher softening temperature…

General purpose polystyrene (GPPS)
Polystyrene, referred to as PS. PS is a thermoplastic non-crystalline resin, which is polymerized from styrene monomers. It can be polymerized by a variety of synthetic methods. The main methods used in industry are bulk polymerization and suspension polymerization. PS is mainly divided into general-purpose polystyrene (GPPS, commonly known as transparent polystyrene), high-impact polystyrene (HIPS,…
