PC/ABS Blend

Updated: 2026-07-15

Overview

PC/ABS blend is a versatile engineering thermoplastic that combines the superior impact resistance and heat tolerance of polycarbonate (PC) with the excellent processability and cost-effectiveness of acrylonitrile butadiene styrene (ABS). This polymer alloy was developed to address the limitations of its parent materials while preserving their beneficial characteristics. The material typically contains 30-70% PC by weight, with the exact ratio determining its final properties. Manufacturers can tailor the blend to achieve specific performance characteristics, making it suitable for a wide range of industrial applications where both durability and precise molding capabilities are required.

Physical and Chemical Properties

PC/ABS exhibits a unique combination of properties including high impact strength (even at low temperatures), good heat resistance (up to approximately 110-130°C depending on grade), and excellent dimensional stability. The material maintains these properties across a wide temperature range, outperforming standard ABS in most mechanical aspects. Chemically, PC/ABS shows good resistance to many acids, alkalis, and oils, though it can be attacked by strong solvents and certain hydrocarbons. The blend offers improved UV stability compared to ABS alone, though outdoor applications may still require additional stabilizers or coatings for long-term use.

Main Applications

The automotive industry represents the largest application sector for PC/ABS, where it's used for interior components like dashboard panels, door handles, and trim pieces. Its ability to withstand temperature fluctuations and resist impacts makes it ideal for these applications. In electronics, PC/ABS is commonly used for laptop and mobile device housings, power tool bodies, and appliance components. The material's electromagnetic shielding properties and flame retardant grades (when specially formulated) make it particularly valuable for these applications. Consumer goods such as luggage, sporting equipment, and furniture components also benefit from PC/ABS's durability and aesthetic qualities.

Safety and Storage

While PC/ABS is generally considered safe for most applications, proper handling precautions should be observed. Processing at high temperatures may release small amounts of styrene or other volatile compounds, requiring adequate ventilation in manufacturing environments. For storage, PC/ABS pellets should be kept in their original packaging in a dry, cool environment below 30°C. Moisture absorption can affect processing characteristics, so many manufacturers recommend drying the material before use if it has been exposed to humid conditions for extended periods.

B2B Procurement Guide

When sourcing PC/ABS, buyers should clearly specify their requirements for mechanical properties, thermal performance, and regulatory compliance. Key considerations include impact strength (often measured by Izod or Charpy tests), heat deflection temperature, and any necessary certifications like UL94 flame ratings or RoHS compliance. Lead times can vary significantly based on the specific grade and color requirements. Many suppliers offer both standard and custom-compounded formulations, with minimum order quantities typically ranging from 500kg to full truckloads depending on the supplier. Pricing is usually volume-dependent, with discounts available for larger purchases and long-term contracts.
