🧩 POP – Polyolefin Plastomer
(A next-generation ethylene copolymer characterized by an excellent balance of elasticity, softness, and thermoplastic processability. It sits between PE and TPE—soft like rubber but processes like standard plastic.)
🔹 What is POP
POP is produced via metallocene catalytic polymerization. At ReplastMD, we treat it as a high-versatility “bridge” material. Its controlled softness and excellent adhesion to PP, PE, and TPO make it ideal for co-extrusion or polyolefin blending. It is frequently used to enhance cold-impact resistance and crack resistance in automotive bumpers, soft-touch interior panels, and high-performance seals.
🔧 Composition & Properties
- Polymer Base: Ethylene copolymer with α-olefins (octene/hexene/butene).
- Density: ~ 0.88 – 0.90 g/cm³.
- Processing Temp: 220 – 250 °C.
- Visuals: Soft, rubbery, smooth, low gloss; translucent, light grey, or matte black.
- Chemical Group: Metallocene Polyolefins.
🚗 Where it is used in the automotive industry
| Component | Example parts | Observations |
| Gaskets / Flexible Caps | VW, Toyota, Peugeot | Cold-weather elasticity and oil resistance |
| Impact Zones / Guards | BMW, Renault | Mechanical damping at low temperatures |
| Soft-touch Panels | Mercedes, Ford | Soft texture and premium aesthetics |
| Co-extruded Layers | Dacia, Hyundai | Perfect compatibility with PP and TPO |
🔧 Welding and Bonding Methods
| Method | Optimal Temp | Observations |
| Hot Air | 220 – 250 °C | Clean weld without burning |
| Heat Plate (Mirror) | ✅ Recommended | Homogeneous bonding with PE, PP, or TPO |
| Extrusion | ✅ Ideal | Perfect for flexible profiles and strips |
💡 ReplastMD Recommendation: Weld at ~240 °C with controlled hot air. POP is an excellent transition material between PP and TPE, ideal for bumpers, gaskets, and flexible zones requiring high shock resistance and cold performance.
