Painting
Available for polypropylene (PP) parts, this finish can be matte, gloss, or textured, with color matching possible.
What is Polypropylene (PP)?
Polypropylene (PP) is a widely used, semi-crystalline thermoplastic known for its excellent chemical resistance, low density, and high impact strength. It is available in two main forms: homopolymer, which is the most common and cost-effective type, and copolymer, which incorporates varying amounts of ethylene to enhance toughness and flexibility.
Polypropylene (PP) Applications
Polypropylene (PP) is used in various parts, including:
- Automotive components
- Packaging containers
- Medical devices
- Textiles and non-woven fabrics
- Consumer goods like storage containers
- Industrial pipes and fittings
- Electrical insulation parts
