Thanks to its unique PG (Plating Grade) properties and creep resistance, T65PG excels in high-demand industries:
Automotive Industry: Primarily used for exterior decorative parts (e.g., radiator grilles, door handles, emblems). Its creep resistance ensures that clips and fixings remain secure under long-term vibration.
Electronics & Electrical: Suitable for high-end smartphone frames and tablet housings, especially those requiring metallized surface finishes.
Sanitary Hardware: Used to replace traditional metals in manufacturing electroplated faucet handles and showerhead brackets, reducing weight and cost.
During the selection phase, customers often compare T65PG with other similar materials:
Surface Finishing: T65PG optimizes the distribution of rubber particles, providing superior plating adhesion and gloss compared to standard grades.
Long-term Load: Standard grades may suffer plastic deformation (creep) under constant pressure, while T65PG maintains its shape across a wider temperature range.
Heat Resistance: The HDT of T65PG (104°C) is approximately 15-20°C higher than standard plating-grade ABS, making it suitable for environments near engine compartments.
Cost Efficiency: While T65PG has a higher unit price, its superior strength allows for thinner wall designs, achieving weight reduction and material savings.
To achieve optimal performance with T65PG, ZiJun Plastics recommends following these injection molding parameters:
Drying: PC/ABS is extremely sensitive to moisture. A desiccant dryer is highly recommended.
Temperature: 100-110°C
Time: 3 – 4 hours (ensure moisture content is below 0.02%).
Melt Temp: 240 – 280°C. Avoid exceeding 300°C to prevent thermal degradation.
Mold Temp: 70 – 100°C. Higher mold temperatures help achieve a more perfect electroplated surface.
Injection Pressure: Maintain moderate to high holding pressure to compensate for shrinkage and improve dimensional stability.
Q1: Is Bayblend T65PG suitable for all electroplating processes?
A: Yes. T65PG is specifically designed for traditional electroless copper/nickel plating processes. Its uniform rubber phase distribution ensures stable anchoring points after etching, resulting in excellent adhesion.
Q2: Why do silver streaks appear on the surface of my T65PG parts after molding?
A: This is usually caused by excess moisture or excessively high temperatures. First, check the dew point of your desiccant dryer to ensure the material is fully dry; second, ensure the nozzle temperature is not too high.
Q3: Does ZiJun Plastics provide small batch purchasing?
A: We offer flexible supply solutions, ranging from sample testing for R&D to full container loads for mass production. All shipments come with original quality assurance and supporting TDS/COA documents.
