Alumina hydrate flame retardant features are non-toxic, odorless, low viscosity, good dispersion, high addition amount, high brightness, high purity, high flame retardancy, and low sodium content. Our company has 8 production lines for the production, research, and development of alumina hydrate flame retardant, offering unique manufacturing advantages in the production of high-brightness, medium-brightness, and micro-fine alumina, including oil absorption rate, viscosity, particle size distribution, brightness, dispersion, thixotropy, and modification. We design excellent alumina application solutions for customers, providing one-stop selection and personalized customization services. The products are widely used in industries such as composite materials (BMC/SMC), electronic copper-clad boards, electrical switches, cables, integrated circuits, insulators, papermaking, building fire-resistant materials and coatings, potting materials, plastic sealing 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, high-purity glass for optical use, and high-purity aluminum salt fillers. We can customize production according to customer needs, such as particle size distribution control, coating, and compounding 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,隔绝oxygen, effectively inhibiting the rise in temperature and thermal degradation of polymers. It suppresses smoke generation by adsorbing and absorbing heat, causing carbonization without producing combustible materials. Suitable for composite materials with processing temperatures below 220°C and plastics with processing temperatures around 300°C.
(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.
3. 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 automated control systems produce products with an oil absorption rate reduced by over 20% compared to 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 smoother the surface and the more significant the reinforcement effect. However, during blending, the viscosity also increases. Please carefully adjust the formula to balance all properties.
2. Mixed with different particle sizes, the appropriate ratio can form a dense filling within the polymer system, enhancing flame retardancy. A rational compound system can prevent the settling or floating of the filler, while also reducing the viscosity of the resin blend under equal amounts of filling, facilitating shear dispersion.
3. Aluminum hydroxide, after ultra-fine processing, has an increased specific surface area, tends to agglomerate, exhibits poor compatibility with polymers, and is difficult to disperse uniformly, affecting the processing properties of the composite material. Hydrophobic aluminum hydroxide has good interfacial compatibility with high polymers; the coated layer on its surface can undergo bond formation with the base material resin groups, reduce the viscosity of the blend, eliminate interface stress concentration, and improve the mechanical properties of the composite material. Therefore, it is recommended to use hydrophobic products.
4. Recommend determining the addition amount through tests; samples (less than 5kg) are available free of charge.
