Applications of flame retarded polyolefins POLYOLEFINS are very COMBUSTIBLE!! Flame retardants should be required for below polyolefins applications:1.wire and cable, such as PE cable, LDPE/EVA cable, PP cable……2.Automotive plastics. Many plastic parts in vehicles are polyolefins, such as Instrumental panel，Door panel，Cowl top……

Halogen Free Flame Retardant PP Composites PP flame retardant composites were prepared with polypropylene and different components by a twin-screw extruder under melting state. The effects of Mg(OH)2,POE and PP-g-MAH on the thermal behaviors, crystalline structure and micro structure of non-halogen flame retardant PP composites were characterized by differential scanning calormetry(DSC), polarized optical microscopy(POM)…

this plastic’s on fire! 4 types of flame retardant plastic additives Like certain pop stars, plastics are generally flammable.Therefore it is often necessary to add flame retardant plastic additives to meet governmental and industry regulatory standards. Flame retardant plastic additives are compounds added to plastics and other materials to inhibit, suppress or delay combustion. These compounds are useful in impending burning in the ignition pha…

What types of products use flame retardants?  While an ever-evolving list of new products—from hair dryers and small appliances to laptops and flat-screen televisions—is incorporated into our homes, offices and commercial environments, we seldom think about how the products are made.  Flame retardants provide consumers with a critical layer of fire protection and are vital to reducing the risks associated with fire.T…

General Flame Retardant Classes 1. Gas Phase Flame Retardants (ex. Halogen, Phosphorus)- Reduce heat in gas phase from combustion by scavenging reactive free radicals, thus inhibiting combustion.2. Endothermic Flame Retardants (ex. Metal Hydroxides, Carbonates)- Function in Gas Phase and Condensed Phase by releasing nonflammable gases (H2O, CO2) which dilutes the fuel and cools the polymer.3. Char Forming Fla…

How do flame retardants work? Flame retardants are added to different materials or applied as a treatment to materials (e.g., textiles, plastics) to prevent fires from starting, limit the spread of fire and minimize fire damage.  Some flame retardants work effectively on their own; others act as “synergists” to increase the fire protective benefits of other flame retardants.

What are the most common elements in flame retardants? Bromine, phosphorus, nitrogen and chlorine are commonly used in flame retardants.  Inorganic compounds are also used in flame retardants, either alone or as part of a flame retardant system in conjunction with bromine,

How Flame Retardants can INCREASE ESCAPE TIME IN FIRES • Flame retardants reduce the risk of ignition and fire spread of many plastic and textile materials which results in more available escape time for occupants.• Time to flashover can increase from 5 minutes to 15 minutes which can make thedifference between escape and fatalities.• Bear in mind that the escape time includes the time to discover the fire, alert other
