🧩 P/E-I-EPDM-TD10 – PE+PP Copolymer + EPDM + 10% Dense Talc
(Semi-flexible copolymeric olefin material, composed of Polyethylene (PE) and Polypropylene (PP) in an isotactic blend (I), modified with EPDM rubber for flexibility and 10% dense talc (TD10) for slight stiffening)
🔹 What is P/E-I-EPDM-TD10
P/E-I-EPDM-TD10 is a two-component polyolefin compound (PE+PP) modified with EPDM for elasticity and 10% dense talc for stability.
It belongs to the TPO / P-E blends family, showing intermediate behavior between PP-EPDM and TPO-TD10. This material is frequently used by Renault, Nissan, Dacia, and PSA for exterior parts where a balance of elasticity, lightweight, and impact resistance is required. Similar markings include T10, T15, or TV10 variants.
🔧 Composition
| Component | Typical Proportion | Role |
| PE (Polyethylene) | 35–40 % | Flexibility and impact resistance |
| PP (Polypropylene) | 35–40 % | Dimensional stability and rigidity |
| EPDM (Synthetic Rubber) | 10–15 % | Vibration damping, cold-weather performance |
| Dense Talc (TD10) | 10 % | Stiffening and shrinkage control |
| Technical Additives | < 5 % | Protection, durability, color stability |
🚗 Automotive Applications
| Component | Example parts | Observations |
| Wheel Arch Liners | Renault, Nissan, Dacia | Semi-flexible, lightweight, matte texture |
| Underbody Shields | Engine covers, transmission guards | Thermally and vibrationally stable |
| Accessory Caps | Sensor supports, door sill covers | Elastic and durable behavior |
| Exterior Aesthetic Elements | Diffusers, bumper corners | Technical, slightly rubbery finish |
🔩 Welding Compatibility
| Mating Material | Compatibility | Observations |
| P/E-I-EPDM, PP-EPDM, PP-TPO, TEO | ✅ Excellent | Compatible structure |
| PP-TD, PP-EPDM-TD20, TPO-TD10 | ⚠️ Fair | Requires transition welding rod |
| TPE-O, TPE-V | ⚠️ Limited | Weldable only with soft TPO rod |
