Alumina Hydrate Product Introduction:
Alumina hydrate flame retardants are characterized by their non-toxicity, odorlessness, low viscosity, good dispersion, high addition amount, high brightness, high purity, excellent flame retardant properties, and low sodium content. Our company has 8 production lines for the production, research, and development of alumina hydrate flame retardants. We have unique manufacturing advantages in the production of high-brightness, medium-brightness, and ultra-fine alumina hydrate, particularly in terms of oil absorption rate, viscosity, particle size distribution, brightness, dispersion, thixotropy, and modification. We offer excellent alumina application solutions, providing one-stop selection and customized services. 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. We 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, dehydration, and decomposition, it forms a dense, solid protective layer on the surface of combustible materials,隔绝oxygen, effectively inhibiting the polymer's temperature rise and thermal degradation. It also suppresses the generation of smoke by adsorption and heat absorption, causing carbonization without producing combustible materials. Suitable for composite materials and plastics 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.
Low in silicon, iron, and sodium – with contents below 0.01%, 0.006%, and 0.2% respectively.
4. Particle size distribution is uniform, concentrated, and controllable.
5. Low oil absorption rate - Modern automatic 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 individually. Particle size is closely related to the properties of the composite material; the smaller the particle size, the better the surface fineness 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. Mixed with different particle sizes, it can form a dense filling within the polymer system at the appropriate ratio, enhancing flame-retardant properties. A rational blending system can prevent the settling or floating of fillers, while also reducing the viscosity of the resin blend under equal filling, facilitating shear dispersion.
3. Alumina hydrate, after ultra-fineness treatment, due to the increased specific surface area, is prone to agglomeration, has poor compatibility with polymers, and is difficult to disperse evenly, affecting the processing properties of composite materials. Hydrophobic alumina has good interface compatibility with high polymers, and the surface coating can undergo bonding reactions with the resin groups of the base material, reducing the viscosity of the blend, eliminating interface stress concentration, and improving the mechanical properties of the composite materials. Therefore, it is recommended to use hydrophobic products.
4. Recommend determining the dosage through testing; samples (less than 5kg) are available free of charge.
Important Notes:
Storage: Store in a cool, dry, and well-ventilated area, away from ground moisture and high heat sources. Transportation: Non-hazardous product; protect from water and moisture during transport, handle with care to prevent damage to packaging. Do not mix with other acidic or alkaline substances. Avoid exposure to air when relative humidity exceeds 80%, and reheat (to 110°C) if necessary before use. After use, ensure proper sealing to prevent moisture; it is recommended to use the contents upon opening the packaging.
Product Packaging:
Inner plastic, outer woven film bags in kraft paper packaging, net weight per bag: 50kg, 40kg, 25kg, or in bulk ton bags; also available for custom packaging according to customer requirements.
