🧩 TPE-O-TD30 – 30% Talc Filled Olefinic Elastomer
(Stiffened olefinic elastomeric material, resulting from the blend of elastic polyolefins (TPE-O) with 30% fine talc (TD30) for a combination of elasticity, controlled rigidity, and dimensional stability)
🔹 What is TPE-O-TD30
TPE-O-TD30 is part of the olefinic elastomer (TPE-O) family — hybrid materials between TPO and TPE that combine the flexibility of rubber with the processability of thermoplastics.
The addition of 30% talc makes it more rigid and stable while maintaining good impact and cold resistance. It is frequently used for wheel arch liners, shields, and underbody protections where a semi-flexible, shock-resistant material is required that maintains its shape under heat and vibration. Similar markings include TD20, TD40, PP-TPO-TD30, or P/E-I-TD30.
🔧 Composition
| Component | Typical Proportion | Role |
| TPE-O (Olefinic Elastomer) | 65–70 % | Elasticity and cold flexibility |
| Fine Talc (TD30) | 30 % | Stiffening and dimensional stability |
| Additives (UV) | < 5 % | UV protection and thermal aging resistance |
🚗 Automotive Applications
| Component | Example parts | Observations |
| Wheel Arch Liners | Renault, Nissan, Dacia | Semi-flexible, vibration resistant |
| Engine Shields / Underbody | Large injected parts | Stable at 120–130 °C |
| Lower Caps & Trims | Side panels, sills | Matte finish, good noise damping |
| Semi-rigid Interior Parts | Sensor covers, protectors | Elasticity with low shrinkage |
🔩 Welding Compatibility
| Mating Material | Compatibility | Observations |
| TPE-O, TPO, PP-TPO, P/E-I | ✅ Excellent | Olefinic family |
| PP-EPDM, PP-TD, P/E-I-TD | ⚠️ Fair | TPO welding rod recommended |
| TPE-V, TEO, TPE-S | ⚠️ Limited | Requires lower temperatures |

🛠️ TPE-O-TD30 Welding at ReplastMD
| Method | Temperature | Observations |
| Hot Air | 230 – 250 °C | Recommended – TPO / TPE-O rod |
| Heat plate (Mirror) | 220 – 240 °C | Clean bond, no deformation |
| Extrusion | 230 – 250 °C | Ideal for thick shields and liners |
💡 ReplastMD Recommendation: use TPO or TPE-O welding rods; clean the surface thoroughly and apply constant air flow with low pressure.
