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; its structure is similar to that of DOPO derivatives, yet its performance surpasses theirs.
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 applications requiring ultra‑high frequency and ultra‑low loss, PHH‑L exhibits lower dielectric loss and reduced linear thermal expansion.
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.
