The advantages of the PP pen case


Polypropylene, abbreviated as PP(PP pen case), is a colorless, odorless, non-toxic and translucent solid substance.  Polypropylene(PP pen case) is a kind of thermoplastic synthetic resin with excellent performance.PP pen case is a colorless and translucent thermoplastic lightweight general-purpose plastic. With chemical resistance, heat resistance, electrical insulation, high-strength mechanical properties and good high wear-resistant processing properties, polypropylene has been rapidly developed and applied in many fields, such as machinery, automobile, electronics and appliances, construction, textile, packaging, agriculture, forestry and fishery, food industry and so on.  In recent years, with the rapid development of China's packaging, electronics, automobile and other industries, it has greatly promoted the development of China's industry.  Moreover, because of its plasticity, polypropylene materials are gradually replacing wooden products, and high strength, toughness and high wear resistance have gradually replaced the mechanical function of metals. In addition, polypropylene has good grafting and composite functions, and has great application space in concrete, textile, packaging, agriculture, forestry and fishery.(PP pen case)
