PET (polyethylene terephthalate)
It has high density and strong hygroscopicity, requiring dehumidification and drying prior to processing; the flowability of pellets and bottle flakes is highly sensitive to temperature changes.
PP (polypropylene)
Lightweight, heat-resistant, and easily crystallizable, it can be used to manufacture injection-molded parts, nonwoven fabrics, food containers, sheets, and corrugated pipes.
PE (polyethylene, collectively referring to HDPE, LDPE, and LLDPE)
It is resistant to low temperatures and to acids and alkalis, with excellent chemical stability.
LDPE (low-density polyethylene)
It has a soft texture, excellent toughness, and good melt flow, and is commonly used for films, flexible packaging, hoses, and coating materials.
