🧩 P/E-I-TD10 – PE+PP Copolymer + 10% Dense Talc
(Semi-flexible copolymeric olefin material, composed of Polyethylene (PE) and Polypropylene (PP) in an isotactic structure (I), filled with 10% dense talc (TD10) for moderate rigidity and stability)
🔹 What is P/E-I-TD10
P/E-I-TD10 is a polyolefin copolymer (PE+PP) modified with dense talc, used in technical applications where a balance between rigidity and flexibility is required.
It is a softer variant of the P/E-I-T20 material, frequently used by Renault, Dacia, Fiat, and Nissan for exterior components and underbody protections. It is valued for its lightweight, controlled elasticity, and good impact resistance at low temperatures. Similar markings include T10, T15, TD15, or TX10.
🔧 Composition
| Component | Typical Proportion | Role |
| PE (Polyethylene) | 40–45 % | Elasticity, cold impact resistance |
| PP (Polypropylene) | 40–45 % | Structural stability and rigidity |
| Dense Talc (TD10) | 10 % | Light stiffening, dimensional stability |
| Additives | < 5 % | Thermal protection and stable color |
🚗 Automotive Applications
| Component | Example parts | Observations |
| Wheel Arch Liners | Renault, Dacia, Fiat | Semi-flexible, matte, vibration-resistant |
| Underbody Shields | Engine/transmission covers | Lightweight, elastic, shock-absorbing |
| Interior Panels / Covers | Sensor housings, side guards | Good thermal stability |
| Lower Exterior Caps | Sill decorations, bumper corners | Matte finish, low shrinkage |
🔩 Welding Compatibility
| Mating Material | Compatibility | Observations |
| P/E-I, PP-TPO, PP-TD, TEO | ✅ Excellent | Common material family |
| PP-EPDM, TPO-TD10, P/E-I-T20 | ⚠️ Fair | PP-TPO rod recommended |
| TPE-O, TPE-V | ⚠️ Limited | Weldable only for thin parts |
| PA, PC, PVC, ABS, PET | ❌ Incompatible | Chemically and thermally incompatible |

🛠️ P/E-I-TD10 Welding at ReplastMD
| Method | Temperature | Observations |
| Hot Air | 230 – 250 °C | Recommended – TPO / PP-TPO rod |
| Heat plate (Mirror) | 220 – 240 °C | Clean weld, no deformations |
| Extrusion | 230 – 250 °C | For thick or stressed parts |
💡 ReplastMD Recommendation: use TPO or PP-TPO welding rods, clean the surface with isopropyl alcohol, and apply uniform air flow.
