polypropylene (PP) is a polyolefin thermoplastic. Polyolefins are partially crystalline thermoplastics which exhibit very high chemical resistance because of their non-polar nature. They include both polypropylene and polyethylene in various modified forms and, because they can be processed easily by conventional methods, are important plastics in widespread use.
polypropylene has a very low specific density of 0.91g/cm3 and is one of the lighter plastics. Its rigidity, hardness and strength plus the ability to be easily welded make it ideal for use in corrosion-resistant applications. It has good electrical properties and a high operating temperature.
polypropylene is non-toxic and authorised for use in the food sector; it is also resistant to diluted acids, alkali and salt solutions, water, alcohol and petrol.
