Distinguishing Features of PP and PE Plastics: A Comparative Analysis

Distinguishing Features of PP and PE Plastics: A Comparative Analysis

Comparing polypropylene (PP) and polyethylene (PE) in terms of UV resistance, it's evident that PP exhibits minimal resistance to ultraviolet rays in comparison to PE. On the contrary, PE possesses a melting point that is situated at a lower temperature than PP. Notably, PE can adopt a transparent state, whereas PP is constrained to achieving a translucent appearance. Regarding chemical resistance, PP marginally surpasses PE in terms of both rigidity and chemical stability.

What represents the prevalent method of production for plastics materials?

The process of Injection Molding, abbreviated as IM, involves the precise insertion of heated and liquefied thermoplastic material into a pre-designed mold cavity. This technique is the preeminent choice for large-scale, efficient production of plastic components.
