Description
These premium dark grey welding rods are designed specifically for the repair and fabrication of thermoplastic components made from PPC (polypropylene copolymer). Supplied in convenient 2 kg coils and available in a range of profiles, they offer reliable, high-strength welds for both professional and workshop environments.
Ideal for plastic fabricators, maintenance teams and repair specialists, these PPC welding rods deliver consistent performance when used with hot air or extrusion welding equipment. Their dark grey colour provides a discreet, professional finish on matching substrates in automotive, industrial and engineering applications.
Product Features
- Material: high-quality PPC (polypropylene copolymer) welding rod for thermoplastic repair and fabrication.
- Profile options: 3 mm round and 4 mm round profiles for general-purpose plastic welding tasks.
- Triangle profiles: 4.5 mm, 5.7 mm and 7 mm triangular rods for higher build-up, gap filling and structural repairs.
- Special tricore option: 5.2 mm tricore profile for enhanced melt flow and strong, consistent fusion joints.
- Standard coil weight: supplied in 2 kg coils for efficient handling, storage and reduced changeovers.
- Colour: dark grey finish for neat, low-visibility repairs on matching PPC components.
- Suitable for: hot air and extrusion welding equipment commonly used in plastic fabrication and repair.
Key Features and Benefits
- Ensures strong, durable welds on PPC substrates, helping prolong the service life of plastic parts and assemblies.
- Multiple rod profiles allow you to match the weld geometry to the job, improving joint integrity and finish quality.

Frequently Asked Questions
Can these welding rods be used on plastics other than PPC?
These rods are formulated specifically for PPC (polypropylene copolymer) and should be used on matching or compatible PPC substrates for best results. Using them on other plastic types may result in weak or unreliable welds, so always confirm the base material before welding.
What welding equipment do I need for these PPC rods?
They are suitable for use with standard hot air plastic welders and extrusion welders fitted with appropriate nozzles for the selected rod profile. Ensure the equipment can reach the correct processing temperatures for PPC and follow the manufacturer’s guidelines for settings and technique.
How do I choose the right profile and size of welding rod?
Round profiles (3 mm and 4 mm) are typically used for lighter repairs, smaller joints and detailed work, while the larger triangle profiles (4.5 mm, 5.7 mm and 7 mm) are better for filling gaps, building up material and structural repairs. The 5.2 mm tricore option is often chosen where improved melt flow and strong, consistent fusion are important. Match the profile to the thickness of the material and the size of the joint.
