The products are widely used in various industries such as composite materials (BMC/SMC), electronic copper clad boards, electrical switches, cables, integrated circuits, insulators, papermaking, fire-resistant building materials and coatings, potting materials, plastic encapsulation materials, LED encapsulation materials, high-performance adhesives, artificial leather, polyurethane, polyamide, polyolefins, chlorinated polyvinyl, epoxy resins, unsaturated polyester resins, phenolic resins, synthetic rubber, and various functional high polymer flame retardant materials. Special fillers for agate, artificial marble, optical high-purity glass, and high-purity aluminum salt fillers. The company can customize production according to customer needs, such as particle size distribution control, coating, and compound treatment.
Product Features:
High purity
(1) Excellent flame-retardant and smoke-suppressing properties—Upon heating and dehydration, it decomposes to form a dense, solid protective film on the surface of combustible materials, which effectively blocks oxygen and inhibits the rise in temperature and thermal degradation of polymers. It also suppresses the generation of smoke by adsorbing and absorbing heat, causing carbonization without producing flammable materials. Suitable for composite materials and plastics with processing temperatures below 220°C and around 300°C respectively.
(2) Excellent Insulation Properties – The fluidized bed purification process significantly reduces the content of impurities such as iron, sodium, and potassium ions.
2. High brightness – Does not interfere with product dyeing and enhances product color saturation and appearance.
Low silicon, low iron, low sodium — contents are respectively below 0.01%, 0.006%, and less than 0.2%.
4. Uniform and controllable particle size distribution.
5. Low oil absorption rate - Modern automatic control systems produce products with an oil absorption rate 20% lower than traditional mechanical crushing systems.
Usage Instructions:
1. Selection should be based on the performance requirements of the product when used alone. Particle size is closely related to the properties of the composite material; the smaller the particle size, the finer the surface texture and the more pronounced the reinforcing effect. However, the viscosity is also higher during blending, so please carefully adjust the formula to balance all properties.
2. Utilizing a blend of different particle sizes, a dense packing can be formed within the polymer system at the appropriate ratio, enhancing flame retardancy. A well-mixed compound system can prevent the settling or floating of the filler, while also reducing the viscosity of the resin blend under equal filling, facilitating shearing and dispersion.
3. After ultra-fining, aluminum hydroxide has a larger specific surface area, tends to agglomerate, and has poor compatibility with polymers, making it difficult to disperse uniformly, which affects the processing properties of composites. Hydrophobic aluminum hydroxide has good interfacial compatibility with high polymers, and the coated layer on its surface can form bond reactions with the functional groups of the base material resin, reducing the viscosity of the blend, eliminating interface stress concentration, and improving the mechanical properties of the composite. Therefore, it is recommended to use hydrophobic products.
4. Suggest determining the addition amount through testing; samples (less than 5kg) are available free of charge.
Cautionary Notes:
