🧩 PETG+FR – Flame Retardant PETG (Glycol-modified PET)
(A transparent or translucent thermoplastic copolyester derived from PET, modified with glycol (G) for impact resistance and halogen-free flame retardants. Ideal for interior automotive parts and electrical components requiring fire safety and clarity.)
🔹 What is PETG+FR
PETG+FR is the “safety glass” of technical plastics. At ReplastMD, we treat it as a high-clarity engineering material. By adding glycol, PETG becomes more flexible and easier to process than standard PET. The FR (Flame Retardant) additives make it self-extinguishing (UL94 V-0) without compromising its transparency. It’s a lightweight, impact-resistant solution for visual or electrical applications where safety is paramount.
🔧 Composition & Properties
- Polymer Base: Copolyester (PETG) ~90%.
- Flame Retardants: Halogen-free additives ~8–10%.
- Density: ~ 1.28 – 1.35 g/cm³.
- Thermal Limit: Stable up to 120 °C.
- Visuals: Smooth, glossy, transparent or translucent; slightly elastic.
🚗 Where it is used in the automotive industry
| Component | Example parts | Observations |
| Transparent Covers | BMW, Mercedes | Clarity + Fire resistance |
| Electric / LED Housings | VW, Toyota | UL94 V-0 class, good insulation |
| Decorative Interior | Peugeot, Hyundai | Glossy surface, low impact on weight |
| Sensor & Light Shields | Renault, Dacia | UV resistance and thermal stability |
🔧 Welding and Bonding Methods
| Method | Optimal Temp | Observations |
| Hot Air | 230 – 250 °C | Clean weld without carbonization |
| Heat Plate (Mirror) | ✅ Recommended | Uniform, transparent bonding |
| Ultrasonic | ✅ Ideal | Perfect for fine joints and electric housings |
💡 ReplastMD Recommendation: Weld at ~240 °C using controlled hot air or ultrasonic welding for delicate parts. PETG+FR is the ideal choice for transparent caps, electric panels, and interior automotive parts requiring clarity, impact resistance, and fire safety.
