PP does not present stress-cracking problems and offers excellent electrical and chemical resistance at higher temperatures. Oriented polypropylene (OPP) has seen considerable growth, having replaced cellophane in virtually all applications. Structural foam, and low density packging (bead process similar to XPS) TypeĪutomotive components, sailing dinghies, etc. The versatility of the polymer (the ability to adapt to a wide range of fabrication methods and applications) has sustained growth rates enabling PP to challenge the market share of a host of alternative materials in plethora of applications including. Commercial production began in 1957 and polypropylene usage has displayed strong growth from this date. These new polymers with their ability to crystallise soon became popular and polypropylene is now a very successful product in many areas. Natta utilised catalysts developed for the polyethylene industry and applied the technology to propylene gas. Natta produced the first polypropylene resin in Spain in 1954. Polypropylene is one of those most versatile polymers available with applications, both as a plastic and as a fibre, in virtually all of the plastics end-use markets.ġ0 Find a Supplier of Polypropylene or Another Materialįollowing the work by Ziegler in Germany, the process for producing 'stereoregular' polymers was perfected by Professor Giulio Nattain in Italy.

PP, like polyethylene (see HDPE, L/LLDPE) and polybutene (PB), is a polyolefin or saturated polymer. Polypropylene (PP) is a linear hydrocarbon polymer, expressed as CnH2n.
