POLIPROPILENE "PP"
Polypropylene possesses good electrical and chemical characteristics.
It possesses good rigidity and solidity.
It is normally used within a temperature range of +5oC to +90oC and possesses high resistance to chemical agents; it is capable of being welded.
On the other hand it does not stand up well to abrasion and atmospheric agents.
It is a semi-crystalline thermoplastic material, like pe, but is more resistant and rigid and melts at a higher temperature despite having a lower density.
It is a thermoplastic, semi-crystalline material like PE, but is tougher and more rigid and melts at a higher temperature although having a lower density.
Thanks to its non-polarity characteristic, PP is highly resistant to chemicals: it retains its resistance to aqueous solutions containing salts, and strong acids and alkalis in temperatures up to 120oC. Yet, at ambient temperatures it is susceptible to attack from strong oxidising agents such as nitric acid and halogens.
It is available in formulations that improve its resistance to fire (self-extinguishing PPS).
Talcum is one of the fillers most commonly used in PP. It improves its rigidity, dimensional stability, its resistance to heat and ability to slide; in addition it acts as a nucleating agent. The disadvantages associated with it are a reduction in its resistance to impact at low temperatures, the reduction of its weldability and its resistance to oxidation at high temperatures, and the formation of a more opaque surface.
Fields of Use:
Engineering, aerospace, chemical, electrical and building sectors in semi-finished goods such as pipes, connectors, sheets, solid bars and profiles.
It is used to make: tanks, plant components, fans, parts for submerged pumps, rings, flanges, pulleys and gears.
