What is ABS and PC?
Before comparing these two industry workhorses, let’s look at their core definitions and what makes each resin unique.
ABS (Acrylonitrile Butadiene Styrene)
ABS is an amorphous terpolymer known as the ultimate “all-rounder” in engineering plastics. It combines rigidity, toughness, and excellent processability into one cost-effective package.
- Key Advantages: Highly cost-efficient, exceptional dimensional stability, and easy to injection mold. It also offers a premium surface finish that is perfect for secondary treatments like electroplating or painting.
PC (Polycarbonate)
PC is a high-performance amorphous thermoplastic resin. In the manufacturing world, it is often called “bulletproof plastic” due to its near-unbreakable nature.
- Key Advantages: Optical-grade transparency, superior tensile strength, and outstanding thermal resistance that remains stable even under extreme mechanical stress.
To achieve consistent molding results, your production lines need reliable raw materials. We supply a stable portfolio of branded, high-quality ABS granules and top-tier PC resin grades tailored to your precise manufacturing parameters. Whether you need high flow, heat resistance, or flame-retardant properties, our technical distribution team is ready to support your sourcing.
Key Differences: ABS vs PC Material Properties
Material properties determine performance in real-world applications. Comparing abs and polycarbonate reveals significant differences across multiple characteristics. These variations guide your material selection process.
Physical & Mechanical Performance
- Impact Strength: PC offers extreme resistance (“bulletproof grade”) without shattering. ABS provides excellent standard toughness.
- Thermal Resistance (HDT): PC maintains structural integrity up to 120°C – 140°C , while standard ABS softens at 80°C – 100°C.
- Optical Clarity: PC delivers up to 90% light transmission . ABS is inherently opaque.
- UV Weathering: PC has superior baseline outdoor stability. ABS requires chemical UV stabilizers to prevent yellowing.
Processing & Surface Treatment
Flowability & Moldability
ABS is exceptionally converter-friendly with high melt flow rates and minimal warp risk. Conversely, PC exhibits high melt viscosity, requiring robust injection pressures and strict temperature control.
Post-Processing & Finishing
ABS is the industry substrate premier for electroplating and painting due to its butadiene phase. PC excels in receiving hard coatings, anti-scratch finishes, and optical thin-film applications.

Whether your project demands a high-flow ABS granule to reduce injection cycle times, or an impact-modified, heat-resistant PC grade, our portfolio delivers consistent lot-to-lot stability.
Cost & Manufacturing Considerations
Material selection directly dictates Total Cost of Ownership (TCO) and bottom-line profitability, moving far beyond a simple technical debate for procurement officers and financial controllers. Scaling production from a prototype to high-volume injection molding means the price variance between ABS and PC will immediately impact your market competitiveness.
Raw Material Pricing & Cost Discrepancy
Polycarbonate (PC) consistently commands a price premium over Acrylonitrile Butadiene Styrene (ABS) across the global marketplace. Standard commercial PC resin grades typically cost 30% to 50% more per metric ton than standard ABS granules. Complex chemical synthesis and high energy inputs during polymerization drive this gap. Specialized modifications—such as adding flame retardants (FR), optical clarifiers, or glass fiber—can widen this cost differential even further depending on the specific branded grade you source.
When to Choose ABS (Cost Optimization)
The most effective strategy to optimize manufacturing budgets when environments do not demand extreme thresholds:
- Sufficient Performance: Ideal for indoor enclosures, consumer electronics housings, or decorative trim where continuous service temperatures remain under 80°C.
- Complex Geometries: ABS’s superior melt flow behavior reduces injection molding cycle times, minimizes factory scrap rates, and lowers tool wear.
- Maximizing ROI: Prevents costly over-engineering, allowing you to reallocate vital capital toward product marketing or electronics.
When PC is Worth the Premium Investment
Premium price tags transform into a necessary insurance policy when safety and liability are non-negotiable:
- Mandatory Safety: Required for structural flame-retardant compliance (such as UL94 V-0 ratings), medical device housings, or electrical junction boxes.
- Rigorous Environments: The component faces high-velocity drops, continuous mechanical stress, or exposure to elevated temperatures exceeding 100°C.
- Optical Synergy: The design demands high light transmission combined with excellent structural rigidity.
Typical Applications: Where to Use ABS and PC?
Molding a successful commercial product requires aligning polymer properties with the rigorous demands of real-world end-use environments. Selecting the correct resin grade directly ensures product longevity, regulatory compliance, and consumer safety.
