What is polypropylene (PP)?
Polypropyleneis a thermoplastic obtained through the polymerization of propylene, a gaseous byproduct of petroleum refining. This process takes place in the presence of a catalyst, under careful control of temperature and pressure.
POLYPROPYLENE (PP) MOLECULE
Polypropylene can be classified into three types (homopolymer, random copolymer, and high-impact copolymer), all of which can be modified and adapted for specific applications.
- Optimal cost-benefit ratio.
- Versatility: Compatible with most existing processing techniques and used in various commercial applications, such as packaging, the automotive industry, textiles, household goods, medicine, piping, etc.
- Good processability: It is the plastic material with the lowest specific gravity (0.9 g/cm³), which means that less of it is needed to produce a finished product.
- Vapor barrier: prevents moisture transfer, which can be used to protect various foods.
- Good organoleptic, chemical, strength, and transparency properties.
