🧩 ASA+PC – Acrylate Styrene Acrylate + Polycarbonate
(Premium technical material, impact, UV, and high-temperature resistant, combining the toughness of polycarbonate with the weather stability and acrylic gloss of ASA. Ideal for exterior and interior automotive components.)
🔹 What is ASA+PC
ASA+PC is an advanced technical blend obtained by combining ASA (Acrylate Styrene Acrylate) – known for its UV resistance and color stability – with PC (Polycarbonate) – which brings toughness, rigidity, and high thermal resistance.
The result is a glossy, durable, and heat-stable material, capable of maintaining its properties even under severe conditions. It is widely used in mirror housings, headlight frames, spoilers, air diffusers, and premium exterior components.
🔧 Composition
- ASA (Acrylate Styrene Acrylate) – 40–60 %
- PC (Polycarbonate) – 40–60 %
- UV and thermal stabilizers – 1–5 %
- Density: 1.10–1.18 g/cm³
- Melting Point: ≈ 250–270 °C
- UV Resistance: Excellent.
- Impact Resistance: Very high, stable in cold and heat.
🚗 Where ASA+PC is used in the automotive industry
| Component | Example parts | Observations |
| Body Exterior | Mirror caps, headlight frames, sensor covers | UV resistance and durable gloss |
| Premium Interior | Dashboards, decorative panels, console | Aesthetic gloss, dimensional stability |
| Bodywork / Tuning | Colored exterior elements | Maintains color and shape over time |
| Technical Equip. | Supports, electronic housings | Good insulation, thermal durability |
🔧 Welding Temperature and Methods
| Method | Optimal Temperature | Observations |
| Hot Air | 260 – 280 °C | Clean weld, uniform melting |
| Heat Plate (Mirror) | 250 – 270 °C | Smooth, controlled joint |
| Manual Extrusion | 240 – 260 °C | Recommended for cracks and mounts |
🔩 What to Weld ASA+PC With (Material Compatibility)
As an acrylic-carbonic hybrid material, ASA+PC is compatible with ASA, PC, and ABS/PC or ABS/ASA blends.
✅ Compatible with:
- ASA+PC ↔ ASA+PC / PC+ASA / PC / ASA – ideal combination.
- ASA+PC ↔ ABS+PC / ABS+ASA / ABS+PMMA – good compatibility.
- ASA+PC ↔ ABS-HI / SAN – partially compatible.
❌ Incompatible with:
- PP, PE, PA, PVC, TPO – completely different melting points.
💡 ReplastMD Recommendation:
Use ASA+PC or PC+ABS rods at a temperature of 270–280 °C. Heat uniformly; avoid overheating (to prevent matting of the ASA layer). Finally, you can use a quick pass of hot air to equalize the gloss.
