Polypropylene (PP) is the most widely used material for chemical-technical applications. Compared to PE, it displays greater rigidity particularly in the upper service temperature range (up to +100°C). Its key characteristics also include excellent chemical resistance, good long-term properties when exposed to various substances and high stress crack resistance.
There are two types of polypropylene: homopolymers (PP-H) and copolymers (PP-C). PP-H consists entirely of a combination of propylene monomers and covers a service temperature range from 0°C to +100°C. PP-C features a chemical combination of propylene monomers and ethylene monomers, which increases the material's impact strength at low temperatures. PP-C covers a service temperature range from –20°C to +80°C and is less rigid than PP-H. SIMONA offers best-in-class products of the highest possible quality in both categories – for applications that demand maximum safety and reliability.
