Key Advantages

 

 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.
   

Applications

 

• Copper Clad Laminates (CCL): FR-4, high-frequency CCL, halogen-free CCL

• Electronic Packaging Materials: Semiconductor substrates, IC carriers

• Other Flame Retardant Composites: PCB solder mask, electronic adhesives
