About Polypropylene:

It is a linear structure based on the monomer CnH2n. It is manufactured from propylene gas in presence of a catalyst such as titanium chloride. Beside PP is a by-product of oil refining processes.

Properties of polypropylene

Light in weight For example, PP has the lowest density (i.e 0.90-0.92 g/cm3) of the resins.
Excellent resistance to stress and high resistant to cracking (i.e. it has high tensile and compressive strength)
High operational temperatures with a melting point of 160°C
Excellent dielectric properties
It is highly resistant to most alkalis and acid, organic solvents, degreasing agents and electrolytic attack. On the contrary is less resistance to aromatic, aliphatic and chlorinated solvents and UV.
Non-toxic
Non-staining
Easy to produce, assembly and an economic material

Application of Polypropylene

In general Polypropylene can be used for manufacturing housewares, packaging, monofilaments and film tapes, pipes, containers, boat hulls, seat shells and automotive parts e.g. battery cases and bumpers, semiconductors etc. Its resistance to bacterial growth makes it suitable to be used in medical equipment.
