What is PC/ABS?
PC+ABS (Polycarbonate + Acrylonitrile Butadiene Styrene) is a blended thermoplastic that combines the best qualities of polycarbonate (PC) and ABS. This alloy offers enhanced impact resistance, strength, and heat resistance, while maintaining the ease of processing and aesthetic properties of ABS. The combination of PC’s high toughness and optical clarity with ABS’s rigidity and surface finish results in a versatile material used in demanding injection molding applications. PC+ABS is commonly used in industries where durability and appearance are both important, such as in consumer electronics and automotive components.
The main Benefits of PC/ABS for Injection Molding
| Benefit | Description |
|---|---|
| Enhanced Processability | Combines ABS’s easy flow with PC’s high-temperature stability. |
| Reduced Shrinkage & Warpage | Minimal post-molding dimensional changes (±0.5–0.7%), critical for tight-tolerance parts. |
| High Impact Resistance | Maintains toughness even at low temperatures (down to -30°C), reducing brittle failures. |
| Energy Efficiency | Shorter cycle times vs. pure PC due to faster cooling (optimized thermal properties). |
| Surface Quality | Excellent for plating, painting, or textured finishes (e.g., automotive interiors, consumer electronics). |
| Chemical & Heat Resistance | Withstands automotive fluids (oils, greases) and temperatures up to 120°C. |
| Flame Retardancy | Easily formulated to achieve UL94 V-0/V-2 ratings without major process adjustments. |
| Design Flexibility | Enables thin-walled geometries (down to 1.0–1.5mm) while maintaining strength. |
| Cost-Effectiveness | Lower processing costs than pure PC (reduced scrap rates, energy savings). |
| Mold Release Stability | Low sticking tendency, minimizing ejection issues and surface defects. |
PC/ABS vs ABS vs PC – Injection Molding Materials Compared
| Benefit | PC/ABS | ABS | PC |
|---|---|---|---|
| Enhanced Processability | ✅ Easy to mold, combines PC’s heat stability & ABS’s flowability | ✅ Excellent flow, low processing temp | ❌ Requires higher temp & pressure, more complex to mold |
| Reduced Shrinkage & Warpage | ✅ Low shrinkage (±0.5–0.7%), good dimensional stability | ❌ Higher shrinkage, less dimensionally stable | ✅ Good dimensional stability |
| High Impact Resistance | ✅ Tough, even at low temps (down to -30°C) | ❌ Moderate impact strength; brittle in cold | ✅ Very high toughness & impact resistance |
| Energy Efficiency | ✅ Faster cycle times than PC | ✅ Fast cooling & cycle time | ❌ Slower cycle time due to heat retention |
| Surface Quality | ✅ Excellent: supports painting, plating, texturing | ✅ Good finish, easy to texture | ❌ Needs special treatment for plating, less aesthetic |
| Chemical & Heat Resistance | ✅ Up to 120°C, resists automotive fluids | ❌ Weaker chemical & heat resistance (~90–100°C) | ✅ High heat (up to 135°C), good chemical resistance |
| Flame Retardancy | ✅ Easily modified to meet UL94 V-0/V-2 | ❌ Needs additives, less flame retardant | ✅ Inherently flame resistant, easy to modify |
| Design Flexibility | ✅ Thin walls possible (1.0–1.5mm), high strength | ✅ Very good, but less strength | ❌ Strong but not ideal for thin walls |
| Cost-Effectiveness | ✅ Lower cost than PC, better properties than ABS | ✅ Low cost | ❌ Higher material & processing cost |
| Mold Release Stability | ✅ Low sticking, smooth ejection | ✅ Easy mold release | ❌ Tends to stick, needs mold release agents |
Summary:
PC/ABS offers a balanced solution between performance and cost — ideal for demanding but cost-sensitive applications.
ABS is the most economical, best for general-purpose housings.
PC is premium-grade for maximum durability, but at a higher cost and processing complexity.
