Product Introduction: Flame Retardant Reinforced PC GF10 (Injection Grade)
Key Features: High Flame Retardancy, Enhanced Rigidity, Low Shrinkage, Excellent Electrical Insulation
1. Product Overview
PC GF10 is a high-performance engineering plastic based on Polycarbonate (PC) resin, reinforced with 10% surface-treated chopped glass fibers (GF) and an advanced eco-friendly flame retardant system.
By adding 10% glass fiber, this material significantly improves tensile strength and heat deflection temperature compared to standard PC, while retaining a high level of impact resistance. Combined with its superior flame retardancy, it is an ideal choice for safety-critical housings in electronics, telecommunications, and precision equipment.
2. Core Advantages
Excellent Flame Retardancy: Typically achieves UL94 V-0 (at 1.5mm/3.0mm) ratings. It features self-extinguishing properties, meeting the most stringent fire safety standards.
Balanced Physical Properties: The 10% GF reinforcement increases stiffness and hardness without making the material overly brittle, ensuring parts are both rugged and durable.
High Dimensional Stability: Low water absorption and low mold shrinkage (0.2% - 0.4%) ensure long-term stability for precision molded parts, preventing dimensional deviation caused by environmental changes.
Enhanced Heat Resistance: The addition of glass fiber raises the Heat Deflection Temperature (HDT), allowing the material to maintain its mechanical integrity in high-temperature environments.
Electrical Safety: Offers excellent dielectric strength and arc resistance, effectively preventing electrical leakage or breakdown in high-voltage components.

Benefit: Meets high-level fire safety requirements while providing enough structural strength to support internal metal components.
II. Telecommunications & IT Equipment
Applications: Router housings, server brackets, precision switch components, and small structural parts for 5G base stations.
Benefit: Ensures no dimensional deformation under the heat generated by high-frequency operation while guaranteeing fire safety.
III. Automotive Electronics
Applications: On-board charger housings, relay cases, fuse boxes, and sensor brackets.
Benefit: Withstands high-temperature environments inside the vehicle and provides excellent mechanical protection.
5. Injection Molding Recommendations
Drying: PC is extremely sensitive to moisture. It must be dried at 110-120 degrees Celsius for at least 4 hours. Moisture content should be kept below 0.02%.
Melt Temperature: 270 - 300 degrees Celsius. Adjust based on wall thickness; avoid long residence times at high temperatures to prevent flame retardant degradation.
Mold Temperature: 80 - 110 degrees Celsius. Higher mold temperatures help improve surface finish, reduce "floating fibers," and eliminate internal stress.
Injection Speed: Moderate to high speeds are recommended to obtain a better surface appearance for glass-filled materials.
