Features of Halogen Free Flame Retardant

Fine, white crystalline powder, non-toxic, odorless, with a smooth feeling; Insoluble in water and most organic solvents.

As a halogen-free flame retardant suitable for nylon, melamine cyanurate is particularly suitable for the use of two pure nylon types, nylon 6 and nylon 66. Melamine cyanurate has various advantages such as extremely low application cost, superior electrical performance, mechanical performance, and coloring performance. Color stability. Good electrical performance. Meet environmental requirements.

Types of Halogen Free Flame Retardant

Intumescent flame retardants

Intumescent flame retardants are char-forming additives that form a protective barrier of carbon foam film in the condensed phase. The protective layer is formed on the polymer's surface in response to heat, which protects the product from being burnt.

Organophosphorus flame retardants

Organophosphorus flame retardants react chemically with free radicals in the gas or condensed phase during combustion. They act as radical scavengers that are activated by the rise of temperature. Unlike halogen compounds, they typically do not need synergists to be effective but can be combined with other halogens to enhance the protection and loading rate.

Endothermic flame retardants

Endothermic flame retardants are mineral-based additives, such as aluminum trihydrate (ath) and magnesium hydroxide (mg(oh)2). They release water and carbon dioxide, which dilute the fuel available for combustion.

Application of Halogen Free Flame Retardant

Automotive interiors

These materials are integrated into car interiors, including dashboards, seats, door panels, and carpets. In the event of a fire, these components release significantly reduced smoke and toxic gases, creating a safer environment for passengers and emergency personnel.

Railway carriages

Halogen-free flame retardant modified materials enhance the fire safety of seats, flooring, and wall coverings in train carriages. Passengers can travel with peace of mind knowing that interior components are designed for increased fire resistance.

9,10-Dihydro-9-oxo-10-phosphonophenanthrene-10-oxide

Aviation cabin materials

Aircraft cabins benefit from the fire-resistant properties of halogen-free materials in seating, wall panels, and overhead bins. Improved fire safety is crucial during emergency situations and evacuations.

Marine interiors

Ships and boats utilize these materials in cabin furnishings, ensuring a reduced fire hazard and minimizing potential harm in the event of a fire outbreak at sea.

FAQ

Q: What is halogen-free flame retardant?

A: Unlike traditional flame retardants, HFFRs do not contain halogens such as chlorine or bromine, making them more environmentally friendly and less harmful to health.

Q: What are non halogenated flame retardant polymers?

A: Ammonium polyphosphate is one of the most popular non-halogenated phosphorus-based flame retardants. Phosphate esters are supplied in liquid form and are highly effective in urethane foams and engineered resin systems.

Q: What are the additives in halogen-free fire retardant?

A: Halogen-free flame retardants such as ATH and MDH also offer a host of additional benefits. They are non-corrosive, inert, non-volatile and economical, all while reducing smoke density and providing environmentally friendly fire retardation.

Q: Are there non-toxic flame retardants?

A: Non-toxic fire retardants are designed to reduce the flammability of materials without the use of harmful chemicals.

Q: Is there a natural flame retardant?

A: Natural fire retardants are substances derived from organic or inorganic materials that reduce the flammability of materials or slow down the spread of fire. These can include materials like wool, certain plant extracts, and mineral-based compounds.
