Shanghai Yunshan Plasticizing Co., Ltd. proudly presents the T45 PC/ABS Alloy – a specially formulated injection molding raw material designed for auto chrome plated parts that demand exceptional metal adhesion. Our material bridges the gap between engineering plastics and decorative plating, offering manufacturers a reliable solution for producing high-gloss, durable automotive components. With years of expertise in polymer compounding, we ensure consistent quality and performance that meets the rigorous standards of the automotive industry.
The T45 grade is engineered to provide superior adhesion to electroplated metal layers, eliminating common issues like peeling or blistering. It combines the impact resistance of polycarbonate (PC) with the processability of acrylonitrile butadiene styrene (ABS), resulting in a material that is both tough and easy to mold. Whether you are producing interior trim, exterior emblems, or functional brackets, this alloy delivers the reliability your production line requires.
Key Features & Benefits
Excellent Metal Adhesion – Formulated with a balanced additive package to ensure strong bonding between the plastic substrate and chrome plating, reducing rejection rates.
High Impact Strength – PC content provides outstanding toughness, making parts resistant to cracking during assembly and in-service.
Heat Resistance – Suitable for under-hood applications where temperatures may reach up to 120°C (continuous).
Good Flow & Moldability – ABS component ensures excellent melt flow, filling complex geometries with ease.
Chemical Resistance – Resists common automotive fluids such as gasoline, oil, and cleaning agents.
Consistent Color & Gloss – Provides a smooth surface finish ideal for subsequent electroplating processes.
Recyclable & Environmentally Friendly – Material can be reground and reused (subject to process conditions).
