PC PBT ALLOY
product details
Built for the Outdoors — The Alloy Engineered Where PC/ABS Reaches Its Limits
Material Overview
PC/PBT is the alloy engineers reach for when the operating environment demands more than amorphous blends can offer. By replacing the styrenic phase of ABS with semi-crystalline polybutylene terephthalate, this material gains a level of chemical resistance, weather durability, and electrical safety performance that opens applications no PC/ABS variant can serve.
Renhong’s PC/PBT compounds are engineered for the next generation of electric mobility and outdoor industrial equipment. The semi-crystalline PBT phase delivers reliable resistance to gasoline, motor oil, brake fluid, road salt, and most automotive cleaners, while the polycarbonate phase preserves impact integrity even at –40°C — supporting cold-climate automotive and industrial deployments across global markets.
Key Features
🧪 Chemical Resistance
Reliable performance against fuels, oils, brake fluids, road salt, and most automotive cleaners — beyond what amorphous blends typically offer.
❄️ Low-Temperature Toughness
Maintains impact integrity down to –40°C, qualifying for cold-climate automotive and industrial applications.
⚡ High CTI for Electrical Safety
Comparative Tracking Index (CTI) values reach up to 600V — qualifying for high-voltage EV charging connectors and inverter housings.
🌞 Weatherability
UV-stabilized grades retain mechanical and aesthetic properties after 1,000+ hours of QUV exposure (ISO 4892-3).
🔥 Glow-Wire Performance
Glow-wire ignition temperature (GWIT) up to 775°C — meeting IEC 60695-2-12 requirements for electrical safety enclosures.
Typical Applications
Automotive Exterior
- Exterior trim panels, rocker moldings, body side cladding
