PP is obtained by polymerization of propylene gas under high pressure. Polypropylene is a low density thermoplastic that is resistant to corrosion. Its resistance to chemical solvents is high.
This polymer has a crystal and semitransparent structure with a density of 0.90 and 0.91 g/cm³ and is one of the lightest thermoplastics. Its melting point is 160-164 °C.
Polypropylene has three forms in general :
1. PPH – Polypropylene Homo polymer
2. PPIC – Polypropylene Block Copolymer
3. PPRC – Polypropylene Random Copolymer
