Halogen Free Flame Retardant

What are non-halogenated flame retardants?

Non-halogenated flame retardants (FR) refer to chemicals that do not contain halogens like bromine or chlorine. Instead, they rely on alternative mechanisms, such as forming a protective char layer or releasing water to cool the combustion process, which helps reduce the spread of fire. These solutions are environmentally friendly as they produce less toxic smoke and do not emit corrosive gases during combustion, making them suitable for various applications.

Our halogen-free flame retardants are formulated to meet the fire safety needs of various industries, ensuring compliance with international standards. These retardants are commonly used in sectors like electronics, construction, and automotive, where fire protection is critical, but safety and environmental impact cannot be compromised. The materials maintain high performance while avoiding the risks associated with traditional halogenated compounds.

The halogen-free flame retardants we offer are designed to minimize the release of toxic gases and reduce the spread of flames, making them ideal for applications such as cable insulation, plastics, and coatings. These additives provide reliable fire resistance while meeting stringent safety regulations, offering industries a sustainable solution for fire protection.

Magnesium Hydroxide Flame Retardant

FAQs
What is the purity level (MgO content) of the brucite?
Brucite is available with varying MgO contents, customized to meet specific application requirements.
Yes. Several surface modification options are offered, including silane and stearic acid treatments.
Yes. A dedicated technical team is available to deliver professional support and guidance.
Brucite is a naturally occurring mineral, belonging to the group of hydroxides. It is commonly found in the form of plate-like or fibrous structures and often occurs alongside minerals like dolomite, calcite, talc, and magnesite. Due to its excellent processing and chemical properties, it serves as a high-temperature refractory material and a fire-resistant electrical material. Additionally, Brucite is a top-quality, eco-friendly, low-toxic, multifunctional halogen-free flame retardant widely used in industries like plastics, rubber, and coatings
Brucite typically refers to the magnesium hydroxide extracted from natural brucite minerals, while synthetic magnesium hydroxide is chemically synthesized. When comparing the two, synthetic magnesium hydroxide generally boasts advantages in purity, whiteness, and particle size distribution.
As an excellent fire-resistant material, Brucite is widely used in industries like plastics, rubber, and coatings. Specifically for cables, Brucite significantly enhances flame retardancy, reducing the risk of fires and offering great application prospects in electrical and cable products
Antimony Trioxide Replacement Flame Retardant refers to a mixture of ingredients designed to replace traditional antimony trioxide in flame retardants
These alternatives help reduce costs, improve compatibility with various systems, provide multifunctionality, and lower toxic heavy metal content, offering a more environmentally friendly option
Both products offer nearly identical flame-retardant effects. However, Antimony Trioxide Replacement features lower heavy metal content and is more environmentally friendly
Both flame retardants deliver similar fire-resistant properties, ensuring a high level of protection.
Yes, it can be widely applied in rigid PVC components. For flexible PVC, such as plastic bags and films, the amount of flame retardant added must be carefully controlled to avoid affecting transparency
Yes, the release of crystalline water from low-smoke halogen-free flame retardants happens progressively throughout the heating process. When the material is heated to around 340-350℃, it begins to decompose, and the bound water molecules start to separate from the structure. As the temperature rises, the decomposition and water release accelerate, reaching the fastest rate of release at approximately 430℃. By the time the temperature hits around 490℃, the decomposition is complete, and all the crystalline water has been released. This staged release of water vapor plays a key role in enhancing the flame retardant properties of the material, as the water vapor helps cool the surrounding environment and reduce the spread of flames
Yes, both ACP (Aluminum Composite Panels) and CCP (Composite Insulation Panels) can use magnesium hydroxide flame retardants. ACP, known for its lightweight and fire-resistant properties, is ideal for building exteriors and signage. CCP, composed of foam materials, provides insulation and moisture resistance. Adding magnesium hydroxide enhances fire safety in both materials without compromising their structural integrity, making them safer and more environmentally friendly.
Yes, flame retardants used in CCP panels are typically halogen-free, minimizing the release of toxic substances during combustion and aligning with environmental trends
These flame retardants enhance fire resistance while maintaining the physical and electrical properties of the laminated boards, ensuring safety under extreme conditions such as high temperatures or electrical sparks
