Product Description

Magnesium hydroxide, also known as brucite (Mg(OH)2), is a non-halogen flame retardant and smoke suppressant used in industries such as plastics, rubber, polyurethane (PU), fibers, and coatings. Derived from minerals like magnesite and dolomite, our magnesium hydroxide undergoes an advanced process of purification, fine grinding, and surface treatment to ensure high whiteness, fine particle size, and efficient flame retardancy. With nearly 30 years of experience in the field, our company has become one of the key contributors to the development of national standards for magnesium hydroxide flame retardants in China.

This inorganic flame retardant is specially designed for use in low smoke halogen-free (LSHF) cables and wires. Developed in collaboration with the Spanish National Research Council in Madrid, this additive offers non-toxic fire protection suitable for a variety of cable applications. The flame retardant is available in different grades, including the HM-2 and HM-2S series, which are optimized based on particle size and surface treatment.

Features

• Made from high-purity magnesium-based minerals, this flame retardant offers effective fire protection while maintaining the integrity of the material

• During combustion, it creates a protective char layer that blocks oxygen from fueling the fire, significantly slowing down the spread of flames and smoke

• A sustainable, halogen-free flame retardant derived from natural minerals, offering a safer, eco-conscious alternative without compromising performance

• When exposed to heat, it releases crystallized water and carbon dioxide, reducing fire spread by cooling the material and lowering the combustion temperature

• Precisely ground for improved dispersion and compatibility, ensuring smooth integration into various materials without affecting their physical properties
