Overview
High-flow impact-resistant PC/ABS is a polymer blend combining polycarbonate (PC) and acrylonitrile butadiene styrene (ABS). This hybrid material leverages the strength and heat resistance of PC with the processability and toughness of ABS, making it ideal for injection molding and extrusion. The blend is engineered for high-flow properties, enabling the production of complex, thin-walled components without sacrificing mechanical performance. Its balanced properties have made it a preferred choice in industries requiring durability and precision, such as automotive and electronics.
Physical and Chemical Properties
PC/ABS exhibits a unique balance of properties, including high impact resistance (even at low temperatures), excellent flow characteristics, and good thermal stability. Its density ranges from 1.10 to 1.20 g/cm³, and it typically melts between 220°C and 250°C. The material is chemically resistant to many oils, greases, and diluted acids, though it may degrade when exposed to strong solvents like acetone or ketones. UV-stabilized variants are available for outdoor applications to prevent yellowing or brittleness over time.
Main Applications
The automotive industry extensively uses high-flow PC/ABS for interior and exterior components such as dashboards, trim panels, and grilles due to its durability and aesthetic finish. In electronics, it is favored for laptop housings, phone cases, and power tool bodies. Consumer goods like kitchen appliances, toys, and sporting equipment also benefit from its impact resistance and ease of molding. Medical applications include housings for diagnostic devices, where sterility and dimensional stability are critical.
Safety and Storage
PC/ABS is generally safe to handle but requires precautions during processing. Melting the material can release fumes, so adequate ventilation or fume extraction is recommended. Workers should use PPE like gloves and safety glasses. Storage conditions should prevent moisture absorption, which can affect processing. Keep pellets in sealed containers or original packaging in a dry environment below 30°C. Avoid prolonged exposure to UV light to maintain material integrity.
B2B Procurement Guide
When sourcing PC/ABS, prioritize suppliers with ISO or UL certifications to ensure quality consistency. Request material datasheets specifying mechanical properties (e.g., impact strength, melt flow rate) and regulatory compliance (e.g., RoHS, REACH). Bulk buyers should negotiate pricing based on volume, with prices typically ranging from $2.50 to $4.50 per kg. Confirm lead times and minimum order quantities (MOQs), as shortages of raw materials like PC or ABS can disrupt supply chains.
