TECHNYL® PROTECT Halogen-Free FR Series
Terminal Blocks · Electronic Connectors · Electrical Safety Solutions
In electrical connection systems, terminal blocks and electronic connectors are critical components for circuit conduction, demanding stringent requirements for flame retardancy, electrical insulation, heat resistance, and mechanical strength. The TECHNYL® PROTECT halogen-free flame retardant series offers multiple high-performance polyamide grades specifically designed for connector applications, meeting UL94 V0 ratings and IEC safety standards.
🔌 Terminal Blocks Application
Terminal blocks are accessories for electrical connections, widely used in industrial control, power distribution, and railway applications. TECHNYL PROTECT series materials offer the following advantages for terminal blocks:
V0 rating at 0.4mm thin wall meets stringent fire safety requirements for terminal blocks.
Highest comparative tracking index rating ensures long-term electrical safety in humid environments.
Excellent filling capability for thin-wall, multi-cavity, complex geometry terminal blocks.
Heat-aging stabilized for long-term reliability under continuous current load.
🔌 Electronic Connectors Application
Electronic connectors are widely used in consumer electronics, home appliances, and automotive electronics. TECHNYL PROTECT series provides the following value for connectors:
Low moisture absorption ensures precise mating and reliable fit.
Tensile modulus of 3300-3800 MPa provides adequate structural strength and impact resistance.
Black and natural color options available for different appearance and identification needs.
Compliant with RoHS and REACH, meeting green manufacturing requirements.
