Le polypropylène (PP) est un matériau économique offrant une combinaison d’excellent physical, mechanical, thermal and electrical properties which are not found in any other thermoplastic. Compared to low or high density polyethylene, it has lower impact strength, but higher working temperature and higher tensile strength.
L’homopolymère de polypropylène homopolymère (PPH) est le plus utilisé. Le PPH offre un good strength to weight ratio and is stiffer than copolymer. These advantages combined with good chemical resistance and weldability make it an ideal material for many corrosion resistant structures.
