- Commodity name: PHH-L Polymeric Flame Retardant
Physical properties:

Appearance

Off-white to white powder

Melting point

>320℃

Decomposition temperature (5%)

T > 372℃

Phosphorus content

Approximately 12%

Note: All data in the table are typical values and should not be construed as product specifications. Packaging options: 25 kg per drum, or 1 kg per bottle, or other packaging configurations as required by the customer.

Product Advantages:
- It is used in flame-retardant systems for high-frequency, high-speed CCLs, high-performance CCLs, FCCLs, and standard FR4 substrates.
- PHH-L is a novel halogen-free flame retardant with a structure similar to DOPO derivatives, yet its performance surpasses that of the latter.
- It is applied in the fields of electronic materials and high-temperature materials, exhibiting characteristics such as excellent high-temperature resistance, a high melting point, and a high glass transition temperature (Tg).
- In ultra‑high‑frequency and ultra‑low‑loss applications, PHH‑L exhibits lower loss and smaller linear expansion compared to cyclophosphazene.
- Halogen-free flame retardant, with excellent environmental and health safety characteristics.
Application:
- It is primarily used in high-frequency, high-speed CCLs, high-performance CCLs, FCCLs, and standard FR4 substrates.
- Applied in the fields of electronic materials and high-temperature materials.
- Flame-retardant system for the protective cover of new-energy batteries.
- Flame-retardant systems for composite materials, copper-clad laminates, adhesives, castables, and other applications.
