Polypropylene, abbreviated as PP, is a colorless, odorless, nontoxic and translucent solid substance. Polypropylene (PP) is a kind of thermoplastic synthetic resin with excellent performance, and it is a colorless and translucent thermoplastic lightweight general plastic.
Polypropylene has chemical resistance, heat resistance, electrical insulation, high-strength mechanical properties and good wear-resistant processability, and has been widely developed and applied in the fields of machinery, automobiles, electronic appliances, construction, textiles, packaging, agriculture, forestry, fisheries and food industry.

Guide to purchasing polypropylene materials
1, raw materials
Pp products are generally made of pp, but many claimed pp materials are not pure pp, so when purchasing, it should be noted that food-grade PP materials that are harmless to human body are the best.
Step 2 show up
Good pp materials are generally transparent or translucent materials, with shiny appearance, beautiful design and no burr, which can be seen through the appearance.
3. Persistence
Heat resistance is an excellent characteristic of pp material. The good heat resistance of pp material is very high, and it will not deform in high temperature water, and can even be disinfected in boiling water. In addition, the impact resistance of pp material is also very high, and it is not easy to break under heavy pressure or impact, leaving no scratches.
