Polypropylene

Polypropylene (PP) is a semi-rigid, translucent polymer with good toughness and weather resistance properties. It is a largely non-polar, partially crystalline thermoplastic with 60 to 70% crystallinity. PP has a density of 0.90 to 0.92 g/cm3, amongst the lowest densities for all plastics. PP Sheets are made in 4 primary grades for application-based usage- in PP-Homopolymer (PPH), PP-Copolymer (PP-C), PP Random Copolymer (PP-R), and block copolymer. PP has replaced many traditional construction materials in various applications, including metals, wood, and concrete.

Chemical and physical properties: Most commercial polypropylene is isotactic and has an intermediate level of crystallinity between that of low-density polyethylene (LDPE) and high-density polyethylene (HDPE); its Young's modulus is also intermediate. PP is normally tough and flexible, especially when copolymerised with ethylene. This allows polypropylene to be used as an engineering plastic. Polypropylene is reasonably economical and has good fatigue resistance. It can retain high tensile strength at elevated temperatures.

The large number of end-use applications for PP is often possible because of the ability to tailor grades with specific molecular properties and additives during its manufacture. For example, antistatic additives can be added to help PP surfaces resist dust and dirt. Many physical finishing techniques can also be used on PP, such as machining. Surface treatments can be applied to PP parts in order to promote adhesion of printing ink and paints.
