Additive Masterbatch Plast flame retardant

Each type of additive masterbatch has some special properties to improve the end plastic product.

FLAME RETARDANT ADDITIVE

We protect against Fire Hazards

Flame retardant additives (FR) are chemical compounds added with an objective to inhibit/retard the ignition/burning of the plastic.They reduce smoke formation and/or prevent the material from melt collapse (anti dripping).

Significance

These additives are common in numerous everyday products to avoid the ignition and burning of plastics. Halogenated flame retardants are highly effective at relatively low load levels. Non-halogen, or halogen free, flame retardants are increasing in demand and include intumescents (phosphorus-based) and metallic oxides.

. Non-halogen flame retardants require a higher load level, and often need additional adjustments to maintain the mechanical properties of the plastic. To prevent combustion, it becomes necessary to design a thermally stable polymer that has a lesser probability of decomposing into combustible gases under heat stress.They do suppress or delay combustion process, impending burning in the ignition phase of Fire.

Mechanism

Flame retardant additives can be compounded with the base polymer or added during the plastic processing step. Sometimes combustion may be prevented by simply adding the flame retardant to a surface layer finish on the final product.

When plastic burns, long-chain molecules of the polymer chain are degraded into smaller hydrocarbon molecules and flammable gases, such as free radicals through a process called pyrolysis. For a fire to begin, fuel, oxygen and an ignition source must be present. Flame retardants work by interfering or eliminating one of these key ingredients, either physically or chemically. There are a few common methods that flame retardants do to inhibit combustion, they are a)Gaseous inhibition , b)Solid char formation & c)Endothermic cooling .

How it works?

The most important flame retardants systems used act either in the gas phase where they remove the high energy radicals H and OH from the flame or in the solid phase, where they shield the polymer by forming a charred layer and thus protect the polymer from being attacked by oxygen and heat.

Most commonly used FR additives comprises of Organic halogenated compounds, especially bromine-based types. They act to halt exothermic processes by trapping high-energy free radicals after they form.

Key advantages

Major advantage for incorporating flame retardant additives into polymers, is to ensure that specific products will be safer to use from a fire standpoint. When exposed to a spark or a flame, the products’ flame retardant qualities will prevent the flame from “catching on” and will hinder further ignition. This is considered essential in products that contain electrical components, or for products made for small children.

Our flame retardant additives are designed to reduce polymer melting, They are also characterized by high thermal stability and high performance. Their effect on product transparency and its process ability is extremely minimal.

Can achieve UL 94 – V0 , V1 , V2 ratings as desiered at different part thickness. Our FR additives are ROHS compliant.

xhibit intermediate blooming resistance and good UV stability as well.
