Flame Retardant Magnesium Hydroxide

The flame retardant magnesium hydroxide produced by Taixing has the core advantages of "efficient flame retardant, low smoke, non-toxic, and long-term stability". Unlike traditional halogen and phosphorus flame retardants, it achieves flame retardant protection through a dual mechanism of "heat absorption and cooling+oxygen and smoke suppression". The product is suitable for many fields such as plastics, rubber, power cables, automotive interiors, building materials, and electronic appliances.

Core strengths

1. Dual flame retardant mechanism, efficient protection upgrade

-Heat absorption and cooling core: It decomposes accurately at 340 ℃ (suitable for most polymer material processing temperatures), absorbing 81.0kJ of heat per mole, rapidly reducing the temperature in the combustion zone, suppressing flame spread, and decomposing at a temperature higher than aluminum hydroxide (200 ℃) to avoid premature decomposition and flame retardant failure during processing.

-Oxygen isolation and smoke suppression synergy: The decomposed water vapor dilutes the oxygen concentration in the air, while the generated magnesium oxide (MgO) forms a dense inorganic flame-retardant carbon layer, blocking heat and oxygen transfer, significantly reducing the amount of combustion smoke released (smoke density DS ≤ 45), and the smoke is non-toxic and odorless, without the production of toxic gases such as hydrogen halides and dioxins.

-Leading flame retardant efficiency: By reducing the addition amount by 15% -20% compared to conventional flame retardants, the same flame retardant level can be achieved. Adding 40% -60% to plastics such as PP, PE, EVA can pass UL94 V0 (1.6mm) certification without significantly affecting the mechanical properties of the substrate.

2. Surface modification technology, excellent compatibility performance

-Customized surface modification: Multiple coupling agents such as silane and titanate are used for surface treatment (optional), with a product activation degree of ≥ 95%. It has excellent compatibility with polymer materials such as PP, PE, EVA, ABS, rubber, etc., with a 30% increase in dispersion uniformity, avoiding problems such as agglomeration and delamination.

-Mechanical performance retention: The modified product can form a stable bond with the substrate, with minimal impact on the material's tensile strength, impact toughness, and elongation at break. The retention rate is ≥ 85%, solving the industry pain point of traditional flame retardants that meet flame retardant standards but have decreased mechanical properties.

3. Environmentally friendly halogen-free characteristics, globally compliant and adaptable

-Full dimensional environmental certification: halogen-free, phosphate free, non-toxic, odorless, free of harmful heavy metals, fully compliant with EU RoHS 2.0, REACH SVHC 233, US Prop 65 and other environmental standards, no toxic gas release after combustion, in line with the global trend of "low-carbon environmental protection".

-Multi scenario safety adaptation: It belongs to non hazardous chemicals, non irritating, non corrosive, and can be used for products that come into contact with the human body or are used in enclosed spaces such as automotive interiors, children's products, electronic appliances, etc. Its safety far exceeds that of halogen flame retardants.

-Environmentally friendly degradation: The product itself and its decomposition products (MgO, H ₂ O) are environmentally friendly substances that can be naturally degraded without causing pollution to soil and water bodies, in line with the concept of circular economy.

4. Long term stable performance, with a wide range of application scenarios

-Temperature and aging resistance: Excellent high temperature resistance, stable performance in an environment of -50 ℃ -200 ℃, strong resistance to heat aging and UV degradation, and continuous stable flame retardant effect throughout the product life cycle (≥ 10 years), without migration or precipitation problems.

-Outstanding weather resistance: moisture-proof, acid and alkali resistant, moisture absorption rate ≤ 0.8% in humid environments (25 ℃, RH85%，24h）， It is not easy to clump during storage and use, ensuring production continuity and product stability.

-Multi functional integration: In addition to flame retardancy, it also has certain acid suppression and adsorption functions, which can adsorb some harmful gases and odors generated during the combustion process of materials, further improving the environmental performance of the product.

Application field

1. In the field of wires and cables

-Power cables/communication cables: used for PVC, PE, XLPE and other cable sheaths and insulation layers. Through flame retardant standards such as GB/T 19666 and IEC 60332, they can suppress flame spread in fires, reduce smoke toxicity, ensure smooth power and communication, and adapt to scenarios such as buildings, rail transit, and new energy.

2. Plastic and rubber fields

-Universal plastics: used for plastic products such as PP, PE, EVA, etc., such as home appliance casings, plastic films, injection molded parts, pipes, etc., certified by UL94 V0, expanding the application scenarios of products in indoor and public places.

-Special rubber: added to chloroprene rubber, styrene butadiene rubber, etc., used for conveyor belts, sealing rings, rubber hoses, etc., to enhance the flame retardancy and aging resistance of rubber products, suitable for industries such as mining, chemical, and machinery.

3. Building materials field

-Fireproof coating: As a flame-retardant filler for expansion type fireproof coatings, it is used on the surface of steel structures and concrete buildings to form an expanded carbon layer during a fire, extending the fire resistance time of the building (≥ 1.5 hours), in accordance with GB 14907-2018 standard.

-Thermal insulation materials: added to insulation materials such as extruded polystyrene board (XPS), polystyrene board (EPS), rock wool board, etc., to enhance the flame retardant rating of the materials to B1 level or above, reduce building fire hazards, and be suitable for commercial buildings, residential buildings, and industrial plants.

-Fireproof doors and windows/wallpaper: used as filling material for fireproof doors and windows, flame-retardant wallpaper coating, to suppress flame propagation and smoke release, ensure personnel evacuation time, and comply with building fire safety design specifications.

4. Other fields

-Textile flame retardant: used for flame retardant finishing of textile fabrics such as polyester and cotton, and adapted to public place textiles such as firefighting suits, curtains, carpets, etc. through flame retardant standards such as GB/T 5455 and ISO 6941.
