With increasingly strict environmental regulations and people's high attention to safety performance, traditional halogen containing flame retardant systems are no longer able to meet the application requirements of PVC (polyvinyl chloride) materials in fields such as cables, building materials, automobiles, and electronics. Especially chlorine/bromine flame retardants that release large amounts of toxic smoke and corrosive gases during combustion are gradually being replaced by halogen-free environmentally friendly flame retardants.

In this context, we have launched a heavy-duty PVC material flame retardant magnesium hydroxide, providing a one-stop solution for PVC modified processing enterprises with higher flame retardant levels, less smoke release, and better environmental performance. This product has been widely used in various scenarios such as wire and cable sheaths, flame-retardant hoses, PVC building profiles, floor substrates, and automotive materials, helping enterprises achieve safety upgrades and green transformation.

1、 Flame retardant magnesium hydroxide: an ideal environmentally friendly flame retardant solution for PVC materials

Magnesium hydroxide (Mg (OH) ₂) is a green, halogen-free, non-toxic inorganic flame retardant with good thermal stability, heat absorption ability, and smoke suppression performance. It exhibits the following significant advantages in PVC flame retardant materials:

✅  Thermal decomposition absorbs heat, flame retardancy and smoke suppression

Magnesium hydroxide decomposes above 300 ℃, releasing a large amount of water vapor that carries away heat, dilutes combustible gases, and forms a magnesium oxide protective layer, effectively preventing flame spread.

✅  Zero halogen environmental protection, non-toxic and harmless

Unlike traditional halogen flame retardants, flame-retardant magnesium hydroxide does not release corrosive chlorine gas or toxic gases during combustion, causing no secondary harm to personnel health and equipment, and complying with international environmental standards such as RoHS and REACH.

✅  Significant smoke suppression and high safety

Experimental data shows that magnesium hydroxide can significantly reduce the smoke density and toxic gas release during the combustion of PVC materials, and improve the visibility and survival rate of personnel evacuation in fire environments.

✅  Enhance the thermal stability of materials

Magnesium hydroxide has good thermal buffering properties and is not easily degraded during high-temperature processing, making it suitable for common processes such as PVC cable materials, extruded pipes, and injection molded products.

2、 Comprehensive adaptation to PVC application scenarios

We specialize in optimizing the formula and dispersibility of magnesium hydroxide for the following PVC flame retardant application areas, ensuring comprehensive improvement of customer production and product performance:

PVC cable material flame retardant (sheath, insulation layer, etc.)

PVC flame retardant decorative building materials (profiles, panels, wall systems)

PVC flame retardant hose and sealing material (automotive wire harness sheath, pipe fittings)

PVC products for low smoke and halogen-free scenarios such as subways, airports, hospitals, etc

PVC flooring, film, thin film and other high standard flame retardant products

3、 Customer value enhancement: not only flame retardant, but also competitiveness

By using our company's PVC material flame retardant magnesium hydroxide, customers can obtain the following significant value:

✅  The product has passed UL94 V-0 flame retardant rating certification

✅  Significantly reduce smoke density and toxicity in fires

✅  Meet halogen-free and RoHS environmental regulations, and adapt to export needs

✅  Improve the heat aging resistance and mechanical performance of cables and building materials systems

✅  Provide customized particle size and processing technology, suitable for different extrusion/injection molding/rolling production lines

Case reference: After a cable material manufacturer introduced our flame-retardant magnesium hydroxide, they successfully upgraded their product from V-2 to V-0, while reducing the total filler content in the system by 5%. The product passed the EU REACH certification, opening up new channels for overseas markets.
