How to Choose the Right PC/ABS Grade?
In simple terms:
For most structural applications requiring the best all-around balance of toughness, heat resistance, and cost-effectiveness, choose PC/ABS General Purpose.
For complex, thin-walled designs such as intricate housings or large panels, select PC/ABS High Flow to ensure complete filling and a superior surface.
For safety-critical electrical/electronic parts that must meet flame retardancy standards, specify PC/ABS Flame Retardant (V-0).
For applications where maximum stiffness, minimal deflection, and higher thermal performance are critical, opt for PC/ABS Reinforced (GF20).

PC/ABS High Flow FAQ
Q1: What properties are typically compromised in High Flow grades, and where are they used?
High Flow grades trade off some tensile strength, flexural modulus, and HDT compared to General Purpose grades. They are primarily used for very thin-walled (below 1.0mm), large flow-length ratio, or highly intricate parts, such as ultra-thin laptop covers, large TV bezels, or automotive grilles with fine details.
Q2: Can mold temperature be lowered when using High Flow grade?
While the material flows well at lower temperatures, maintaining a proper mold temperature (typically 50-70°C) is still recommended for optimal surface gloss, minimizing weld line weakness, and controlling internal stress. Excessively low mold temperature may cause uneven gloss or fiber prominence.
Q3: Is High Flow grade more prone to flashing?
Yes. Due to its excellent fluidity, it more readily enters tiny mold gaps. Therefore, it demands higher mold manufacturing precision and better parting line fit. Ensure adequate clamp force and well-maintained molds during use.
