This
black PP plastic repair kit contains all the essential components needed to perform a durable, professional repair by
plastic welding on polypropylene parts.
PP (Polypropylene) is resistant to almost all organic solvents and greases, as well as most acids and alkalis. It is used across a wide range of industries, including
mechanical and automotive engineering (bumpers, headlight tabs, battery trays), tank and container construction, electrical engineering, medical technology, and packaging.
Technical Material Properties of PP:
Polypropylene (PP) is a thermoplastic polymer from the polyolefin group produced by the chain polymerization of propene. As the second most widely used plastic worldwide after PE, it offers standout performance:
- High Durability: excellent resistance to material fatigue and strong chemical resistance.
- Safe & Hygienic: odorless, skin-friendly, and physiologically harmless (suitable for pharmaceutical and food applications).
- Processing & Bonding: ideal for welding, injection molding, extrusion, and thermoforming. Without special surface pretreatment, PP cannot be painted, printed, or glued reliably—making plastic welding the best repair method.
- Melting Point: approx. 160 °C (320 °F).
- Continuous Service Temperature: max. 100 °C (212 °F).
- Compatible / Similar Plastics: PP/EPDM (Polypropylene / Ethylene Propylene Diene Monomer).
