🧩 PP+TD10 – 10% Talc-Filled Polypropylene
(Lightly stiffened weldable plastic, used in automotive bodywork and technical parts)
🔹 What is PP+TD10
PP+TD10 is a polypropylene filled with 10% talc, used to increase the rigidity and dimensional stability of the plastic without significantly reducing its flexibility.
It is a transitional variant between PP-C and PP-TD20, suitable for parts requiring moderate mechanical strength and low weight.
🔧 Composition
- PP (Polypropylene) – base matrix
- Talc (10%) – natural mineral that reduces shrinkage and increases rigidity
- Additives – UV stabilizers, antioxidants, pigments
- Available in homopolymer or copolymer variants
🚗 Where PP+TD10 is used in the automotive industry
| Component | Example parts | Observations |
| Bodywork | Bumpers, spoilers, trims | Lightweight, rigid, deformation-resistant |
| Technical Interior | Door panels, covers, supports | Thermally stable, matte finish |
| Auxiliary Structures | Sensor housings, lower parts | Easy to process and weld |
| Aftermarket | Extensions, protections, custom elements | Moderate elasticity, good for painting |
🔧 Welding temperatures and methods
| Method | Optimal temperature | Observations |
| Hot air | 260 – 280 °C | Most common service method |
| Heat plate (mirror) | 250 – 270 °C | Flat and stable weld |
| Manual extrusion | 240 – 260 °C | For cracks and thick edges |
| Ultrasonic | — | Only possible for small parts |
🔩 What to weld PP+TD10 with (Material compatibility)
The frequent question “what to weld PP+TD10 with” has a clear answer: with similar materials – PP-TD10, PP-TD20, or PP-C.
The added talc does not change compatibility but influences melting speed and rigidity.
✅ Compatible:
- PP+TD10 ↔ PP+TD10 – ideal combination, stable joint
- PP+TD10 ↔ PP+TD20 / PP+TD30 – good compatibility
- PP+TD10 ↔ PP-C / PP-H – fully compatible, only elasticity differs
- PP+TD10 ↔ PP-GF20 – partially compatible
❌ Incompatible:
- PE, ABS, ASA, PC, PA, PVC – different structure and melting
💡 ReplastMD Recommendation:
Use original PP-TD10 or PP-C welding rods and maintain the temperature at 270 °C.
Clean the oxidation zone and do not overheat — talc reduces gloss and can produce micro-cracks if burned.

🧠 How to identify PP+TD10
- Engraved marking: >PP-TD10< or >PP-T10<
- Yellow-blue flame, smells like paraffin
- Floats in water (density slightly below 1 g/cm³)
- Uniform melting at 270 °C
- Matte surface, fine texture, moderate rigidity
💡 ReplastMD Practical Test: If the part is lightweight, rigid but not brittle, with a matte surface and >PP-TD10< marking → confirmed PP+TD10.
