🧩 P/E-I-TX15 – PE+PP Copolymer + Modified Talc
(Technical copolymeric olefin material, resulting from the blend of Polyethylene (PE) and Polypropylene (PP) with isotactic structure (I), modified with treated talc (TX15) for increased adhesion and superior thermal stability)
🔹 What is P/E-I-TX15
P/E-I-TX15 is an enhanced version of P/E-I-T15 material, where the talc (T) is modified with coupling agents (X)—usually silanes or titanates—for uniform dispersion and controlled rigidity.
This material is frequently used in Renault, Dacia, PSA, and Fiat parts, particularly in shields, housings, and wheel arch liners with a matte finish. It offers mechanical strength, UV durability, and low shrinkage while maintaining impact elasticity.
🔧 Composition
| Component | Typical Proportion | Role |
| PE (Polyethylene) | 35–40 % | Flexibility and impact resistance |
| PP (Polypropylene) | 40–45 % | Dimensional stability and rigidity |
| Modified Talc (TX15) | 15 % | Uniform stiffening, low shrinkage |
| Additives | < 5 % | UV protection and phase compatibilization |
🚗 Automotive Applications
| Component | Example parts | Observations |
| Wheel Arch Liners | Renault, Dacia | Semi-flexible, thermally stable |
| Engine Shields / Underbody | Flat parts with multiple mounts | Dense, rigid, no-gloss material |
| Side Caps / Sills / Trims | Sun-exposed elements | Matte finish, UV stable |
| Sensor Housings / Tech Parts | Caps, protections | High vibration and torsion resistance |
🔩 Welding Compatibility
| Mating Material | Compatibility | Observations |
| P/E-I, PP-TPO, PP-TD, TEO | ✅ Excellent | Olefinic structure |
| PP-EPDM, P/E-I-T20, PP-TX15 | ⚠️ Fair | TPO or PP-TPO rod recommended |
| TPE-O, TPE-V | ⚠️ Limited | Only for flexible sections |
| PA, PC, PVC, ABS, PET | ❌ Incompatible | Chemically and thermally incompatible |
