General:

PP is produced by the polymerization of propylene. After polyethylene is the most important polyolefin from the point of view of applications. It resists the alkali and acid infact it is used in the chemical industry for particulates subject to relatively modest efforts.

Technical features:

• High chemical resistance
• Traction resistance, high in polyolefins
• Low specific weight
• Ease of machining both machines and welding
• Good holding at temperature
• Gray and natural color

Defects:

• Compared to the technopolymer it has low mechanical strengths: traction, flexion, compression, etc. And thermal
• Compared to PE it is more rigid and less resistant to shocks.

Applications:

• Mechanics: it is also used for mechanical parts in corrosive environments; Compared to high molecular weight polyethylene, has higher tensile strength at H.M.W. PE
• Chemical: The highest use of PP is in the chemical industry, high acid and alkaline resistance and higher temperature resistance than PVC is used for components in the galvanic and petrochemical chemical industry for the construction of valves, Flanges, gears, etc.
• Food: Physiologically inert if natural color is approved for use in contact with food
• Electrical: good dielectric characteristics, weather stability make it use in this area
