Product Description:
Specially engineered for copper clad laminate (CCL) applications, our high-performance aluminum hydroxide powder delivers exceptional flame retardancy, high purity, and stable thermal decomposition properties. With ultrafine particle size distribution (D50 0.5-20μm), it ensures uniform dispersion in resin systems, significantly enhancing the flame retardant rating and dielectric properties of CCL while maintaining excellent processing fluidity.

Superior Flame Retardancy
Endothermic decomposition releases water vapor to dilute flammable gases, significantly improving CCL's flame resistance.
Low Dielectric Loss
High purity with minimal impurities ensures stable signal transmission in high-frequency circuits.
Excellent Dispersibility
Ultrafine spherical/near-spherical particles reduce resin system viscosity and improve processability.
Eco-Friendly & Safe
Halogen-free flame retardant compliant with RoHS/REACH standards, ideal for premium electronic materials.
Customization Available
Surface modification (silane coupling agent treatment) option to enhance resin interfacial bonding.
