Brief analysis of PP rod performance and use

Time:2022-10-18 Views:149

PP rod is a semi-crystalline material. It is harder and has a higher melting point than PE bars. Due to the problem of the material PP material temperature above 0℃ is very brittle, so in order to get better application in PP products is added 1~4% ethylene random copolymer or higher ratio ethylene content clamp copolymer. The results are much more dramatic, people are much more efficient.
What are the advantages and disadvantages of PP rod reflected in?
The advantages of PP rod: PP material density is low, has a certain heat resistance, not easy to deformation, high stiffness, high surface strength, high strength of PP rod, high surface strength determines its scratch resistance performance characteristics. Good chemical stability (acid, alkali and salt corrosion resistance to a certain extent), with a certain insulation performance, non-toxic and harmless, uniform color, smooth surface, non-stick, easy installation and maintenance, long service life, easy processing, welding firm and so on. PP material products also have an important characteristic is that there is no environmental stress cracking problem.
