POLYPROPYLENE – PP
Polypropylene (PP): Strength and versatility for your industrial projects
Le polypropylene, also known as polypropylene PP, polypropylene PP5 ou polypropylene PP, is a thermoplastic material widely used for its mechanical, chemical and electrical properties remarkable. Thanks to its rigidity, to hardness and solidity, it is establishing itself as a solution of choice in many industries, despite low impact resistance at low temperatures.
At Plastiservice, we support you in choosing the polypropylene PP the most suitable for your projects, taking into account technical and economic requirements. Our expertise guarantees you personalized solutions to optimize your performance. We offer a range of polypropylene products adapted to your needs, whether semi-finished products or finished machined parts.
The advantages and disadvantages of polypropylene PP
Polypropylene has many advantages that make it an essential material:
Benefits
- Low density : Lightweight, it is ideal for applications requiring easy-to-handle materials.
- High resistance to thermal deformation : Withstands temperatures up to approximately +100°C.
- Good rigidity and surface hardness : Ideal for parts subject to high mechanical stress.
- High resistance to chemicals : Withstands exposure to acids, bases and solvents.
- Physiological safety : Compatible with food and medical applications.
- Weldable : Allows for robust and durable assemblies.
Drawbacks
- Low temperature brittleness : Loses its shock resistance below 0°C.
- Low resistance to oxidation : May require additional processing for specific applications.
- Poor adhesion to glue and paint : Limits the possibilities of aesthetic finishes.
- Not weather resistant : Not suitable for prolonged outdoor use without protection.
Various applications of polypropylene PP
Thanks to its mechanical, chemical and electrical properties, polypropylene PP finds applications in many sectors:
- Chemical and mechanical industry :
- Pump and valve components : Resistant to corrosive substances.
- Seals and supports : Used in demanding industrial environments.
- Electroplating spacers : Meet the specific needs of surface treatments.
- Food and medical sector :
