Applications
BMC/SMC Molding Compounds: Enhances flame retardancy (UL94 V-0) and dimensional stability Epoxy Resin Encapsulants: Used for insulating electronic components Phenolic Resin Molding Compounds: Improves arc resistance and mechanical strength High-Temperature Engineering Plastics: Flame-retardant modification for PA, PBT, etc. Specialty Rubber Products: Boosts heat and flame resistance
Product Advantages
High-Efficiency Flame Retardancy
Decomposition temperature ≥200°C, releases bound water under heat to suppress flames, low smoke & non-toxic, compliant with RoHS/REACH standards.
High Filling Capacity
Uniform particle size distribution enables filler loading ≥60%, reducing material costs.
Excellent Processability
Low oil absorption reduces resin consumption; surface treatment ensures superior dispersion without agglomeration.
Performance Enhancement
Improves dielectric strength (≥15 kV/mm) and comparative tracking index (CTI ≥600V) of composites.
Packaging: 25 kg/bag (moisture-proof composite bag) or ton bags
Storage: Store in a cool, dry place; avoid moisture. Shelf life: 12 months.
