🧩 P/E-I-TV20 – PE+PP Copolymer + 20% Mineral
(Technical copolymeric olefin material, composed of Polyethylene (PE) and Polypropylene (PP) with an isotactic structure (I), filled with 20% mineral (TV20) for enhanced strength and thermal stability)
🔹 What is P/E-I-TV20
P/E-I-TV20 is a PE+PP copolymer modified with neutral mineral filler—often dolomite, treated limestone, or silicate—providing dimensional stability, slightly increased density, and low shrinkage.
It is widely used in the automotive industry (Renault, Dacia, Nissan, Mercedes) for exterior components, shields, and protections requiring moderate rigidity, UV stability, and constant thermal behavior. It belongs to the same family as P/E-I-T20 but features a finer texture and better cold elasticity.
🔧 Composition
| Component | Typical Proportion | Role |
| PE (Polyethylene) | 35–40 % | Elasticity and shock absorption |
| PP (Polypropylene) | 40–45 % | Core structure and rigidity |
| Mineral (TV20) | 20 % | Stiffening, thermal stability, and precise shape |
| UV Additives / Stabilizers | < 5 % | Oxidation resistance and color stability |
🚗 Automotive Applications
| Component | Example parts | Observations |
| Wheel Arch Liners | Renault, Dacia, Nissan | Semi-flexible, matte, lightweight |
| Engine Under-shields | Large flat parts | Stability under temperature and vibrations |
| Exterior Sill Covers | Side panels, shields | Matte surface, uniform density |
| Rigid Technical Panels | Sensor caps, brackets | Dense structure, low shrinkage |
🔩 Welding Compatibility
| Mating Material | Compatibility | Observations |
| P/E-I, PP-TPO, PP-TD, TEO | ✅ Excellent | Olefinic family |
| PP-EPDM, TPO-TD20, P/E-I-TVX20 | ⚠️ Fair | TPO or PP-TPO rod recommended |
| TPE-O, TPE-V | ⚠️ Limited | Only for flexible joints |
| PA, PC, PVC, ABS, PET | ❌ Incompatible | Chemically and thermally incompatible |

🛠️ P/E-I-TV20 Welding at ReplastMD
| Method | Temperature | Observations |
| Hot Air | 230 – 250 °C | Recommended – TPO / PP-TPO rod |
| Heat plate (Mirror) | 220 – 240 °C | Clean and uniform bonding |
| Extrusion | 230 – 250 °C | For thick or structural joints |
💡 ReplastMD Recommendation: use TPO welding rods, maintain constant air flow, and allow for slow cooling for a perfect joint.
