Polypropylene resin is a regular crystalline polymer with a light cream-white particle appearance, odorless, non-toxic, lightweight thermoplastic resin. Its relative density is 0.90 to 0.91, making it the lightest among general resins. It has excellent mechanical properties and heat resistance, with a melting point around 170°C. At 150°C without external force, it does not deform. It also exhibits good chemical stability.
1. Packaging materials: the film made of polypropylene can be used for food packaging, pharmaceutical packaging and daily necessities packaging.
2. Fiber products: polypropylene fiber can be used to make ropes, fabrics, carpets and non-woven fabrics.
3. Plastic products: polypropylene can be made into a variety of plastic products, such as plastic bottles, plastic buckets, plastic pipes, etc.
4. Medical devices: polypropylene has good biocompatibility and can be used in the manufacture of medical devices.
Meticulously packaged in 25kg bags, our high-quality product ensures optimal protection and convenience. Each 20ft container efficiently holds up to 27 tons, perfect for large-scale distribution.
