The PP is very strong in chemistry, process, and cost. It is also very relevant for parts with living hinges or those subjected to repeated bending, thanks to its fatigue resistance.

Chemical resistance and characteristics
Main Features
Chemical resistance
<
Le PP a une excellente résistance chimique globale. Il résiste très bien à de nombreuses solutions aqueuses, sels, bases, hydroxydes, alcools, glycols, ainsi qu’à de nombreuses huiles et environnements de service courants. C’est l’un de ses plus gros avantages en environnement industriel ou packaging.
Its main limitations concern strong inorganic acids, certain powerful oxidising agents, and several aggressive solvents. The final resistance also depends on the thickness, mechanical stresses, temperature, and processing conditions. In simple terms: PP is excellent in general chemistry, but it should not be presented as universal when faced with strongly oxidising or very harsh environments.

Frequently asked questions
Injection at 200–260 °C, mould at 20–80 °C. Excellent flow properties, suitable for complex thin-walled parts. Significant shrinkage (1.0–2.5 %) must be taken into account during mould design. No pre-drying required. Take care to prevent warping of flat parts.
PP (code 5) is recyclable. Recycling streams exist for food packaging, the automotive industry, and general industry. The quality of recycled pellets is sufficient for many applications.
PP is among the most widely used food contact materials (FDA, EU Regulation 10/2011). Approved for all types of food including fatty and acidic foods. Resistant to steam sterilisation (PP random copolymer).
Introduction
The PP est un thermoplastic très utilisé en injection pour les pièces techniques, emballages rigides, bouchons, charnières intégrées, pièces ménagères et composants automobiles. Il est apprécié pour sa lightness, to good chemical resistance, to moisture resistance and above all its very good resistance to fatigue, which makes it a benchmark material for common parts.
