Product Advantages:
- Suitable for flame retardant systems in high-frequency & high-speed CCL, high-performance CCL, FCCL, standard FR4, and other applications.
- PHH-L is a novel halogen-free flame retardant with a structure similar to DOPO derivatives, yet offering superior performance.
- Designed for electronic materials and high-temperature applications, featuring excellent heat resistance, high melting point, and high glass transition temperature (Tg).
- In ultra-high frequency and ultra-low loss applications, PHH-L exhibits lower loss and reduced linear expansion compared to cyclic phosphazene-based flame retardants.
- Halogen-free flame retardant with excellent environmental, health, and safety characteristics.
-
Applications:
- Primarily used in high-frequency high-speed CCL, high-performance CCL, FCCL, standard FR4, and other related fields.
- Applied in electronic materials and high-temperature material sectors.
- Flame retardant systems for protective covers of new energy batteries.
- Flame retardant systems for composite materials, copper-clad laminates, adhesives, castables, and similar applications.
