Product Introduction: High-Performance Low-Temperature Resistant & Flame Retardant PC (White)
1. Product Overview
This product is an advanced Polycarbonate (PC) compound specifically engineered for environments requiring both extreme cold resistance and high fire safety. By integrating a specialized impact-modifier system with a non-halogenated flame retardant package, this material maintains excellent mechanical integrity at temperatures as low as -40°C while achieving a UL 94 V-0 flammability rating.
The high-opacity white finish provides a clean, modern aesthetic with superior hiding power and exceptional resistance to UV-induced yellowing.
2. Core Features
Exceptional Low-Temperature Impact Strength: Specially modified to retain high notched impact strength at -30°C to -40°C, preventing brittle failure or cracking upon impact in freezing conditions.
High-Level Flame Retardancy: Complies with UL 94 V-0 (at 1.5mm/3.0mm), featuring self-extinguishing properties and low smoke emission for enhanced electrical safety.
Superior Thermal Stability: Maintains a high Heat Deflection Temperature (HDT), ensuring dimensional stability and mechanical strength even under high-load operating conditions.
Excellent Color Stability & Aesthetics: Pure white appearance with high surface gloss. Enhanced with high-performance anti-UV additives to prevent yellowing under long-term outdoor exposure.
Robust Mechanical Properties: Inherits the high tensile strength, creep resistance, and excellent electrical insulation properties characteristic of premium Polycarbonate.

4. Application Fields
Thanks to its dual advantage of "Fireproof + Freeze-proof," this material is widely used in:
1. New Energy & Charging Infrastructure
Applications: EV charging pile enclosures, charging gun internal supports, and control panels.
Benefit: Meets impact requirements for outdoor winter use and complies with strict electrical fire safety codes.
2. Outdoor Telecommunications
Applications: 5G base station radomes, outdoor security camera housings, and wireless AP enclosures.
Benefit: The white surface reflects sunlight to reduce heat absorption, while low-temp toughness prevents cracking in northern winters.
3. Power & Industrial Components
Applications: Rail transit lighting housings (High-speed rail/Subway), industrial explosion-proof junction boxes, and smart meter covers.
Benefit: Provides excellent electrical insulation and meets rigorous rail safety flame retardancy standards.
4. Cold Chain & Polar Equipment
Applications: Cold storage LED lighting, cold chain tracking device shells, and polar research instrumentation.
Benefit: Solves the common problem of standard PC becoming brittle in sub-zero environments.
5. Processing Guidelines
Drying: PC is moisture-sensitive. Dry at 120°C for 3–4 hours to ensure moisture content is below 0.02%.
Melt Temperature: 280°C - 310°C. Avoid excessive heat to prevent degradation of flame retardants or discoloration.
Mold Temperature: 80°C - 100°C. Higher mold temperatures help reduce internal stress and improve surface gloss.
