Why Flame-Retardant PC Material is the Smart Choice for Transparent Terminal Blocks

In the world of electrical connectivity, terminal blocks are indispensable components. These compact yet powerful accessories are widely used across industrial,electronic, and electrical sectors, enabling secure and efficient connections between power sources, equipment, and external wiring harnesses. But when it comes to choosing the right housing material for terminal blocks, one option stands out: flame-retardant polycarbonate (PC).

Why Flame-Retardant PC for Terminal Blocks?

Flame-retardant PC is a modified material made by incorporating high-efficiency flame retardants into polycarbonate resin, giving it outstanding fire safety and performance advantages.

Key Benefits Include:

UL94-V0 Flame Retardancy at 1.5mm: Self-extinguishing upon removal from fire, ensuring safety in critical electrical environments.

Halogen-Free & Environmentally Friendly: Meets international RoHS & REACH compliance standards.

High Tracking Resistance: Supports 250V CTI, preventing electrical leakage or short circuits.

Superior Heat Resistance: Withstands deformation at temperatures up to 120°C, maintaining structural integrity.

Excellent Electrical Insulation: Prevents current leakage, improving long-term reliability.

Toughness & Impact Resistance: Protects terminal blocks from cracking or breaking due to impact or pressure during installation and usage.

Chemical Resistance: Resists corrosion from weak acids, weak alkalis, and common oils—making it ideal for harsh environments.

Wear & Scratch Resistance: Maintains appearance and performance even under mechanical stress.

Whether you are a manufacturer of terminal blocks, electrical enclosures, or connectors, our flame-retardant PC compounds help elevate your product safety, performance, and consistency.
