WHAT IS POLYPROPYLENE?
Polypropylene is a thermoplastic obtained by polymerizing propylene, a gaseous by-product of oil refining. It all takes place in the presence of a catalyst under carefully controlled temperature and pressure conditions.
There are three types of polypropylene (homopolymers, random copolymers, and high impact copolymers), which may be modified and adapted for specific uses.
- Optimal cost/benefit ratio
- Versatility: It is compatible with most existing processing techniques; it is used in different business applications such as packaging, the automotive industry, textiles, housewares, medicine, tubing, etc.
- Good processability: It is the plastic with the lowest specific weight (0.9 g/cm3), which means that a smaller amount is needed to obtain a finished product.
- Water vapor barrier: As it prevents moisture transfer, it can be used to protect many kinds of foods.
- Good organoleptic, chemical, strength, and transparency properties.
