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) and scanning electron microscopy(SEM). The results showed that the crystal temperature and nucleation rate of PP were improved by adding Mg(OH)2 and POE acted as nucleation agent. The spherulites of the crystal became small and smashed with Mg(OH)2 in PP, the spread and accumulation of PP molecular chain were hindered by the POE macromolecular chains, and the growth of the spherulites of the crystal was also hindered; then the crystalline degree of PP/ Mg(OH)2,POE was decreased. The interfacial compatibility between PP and Mg(OH)2 by adding PP-g-MAH. When the ration of PP/ Mg(OH)2/POE/PP-g-MAH was 80/100/20/2, the mechanical properties and flame retardant performance of PP/ Mg(OH)2/POE/PP-g-MAH non-halogen flame retardant composites were good.

Flame retardants are generally classified according to their chemical makeup. The most common classes of flame retardants are: Brominated, Phosphorus, Nitrogen, Chlorinated and Inorganic. Brominated Brominated compounds are used for a number of purposes, but the major use is as flame retardants. Bromine interacts with the fire cycle in the gas phase to stop the chemical chain reaction that leads to flame formation and a self-sustaining fire. In essence, brominated flame retardants either prevent a fire from starting in the first place, or significantly slow a fire down. Brominated compounds also can be added to materials like plastic without altering their properties. As a result, they can be used in many applications. Highly effective, brominated flame retardants are used in a variety of materials, including textiles, electronics, building materials, plastics and foams. They are often used in combination with an antimony trioxide synergist. Phosphorus Flame retardants containing phosphorus interrupt the combustion process by promoting [charring." In the presence of a heat source, phosphorus flame retardants release phosphoric acid which causes the material to char and form a thick glassy layer of carbon. This carbonated char stops the decomposition process (pyrolysis) and prevents the release of flammable gases, essentially cutting off fuel to the flame. It also provides a barrier between the material and the heat source. Phosphorus flame retardants are used in some upholstered furniture, foam mattresses, textiles, television casings, rubber and plastics.

The recent tragic fire at Grenfell Tower in North Kensington highlighted the need for effective flame retardant treatments for both household items and materials used in the construction of buildings. Flame retardants slow the rate at which a fire propagates allowing more time for people to escape and for emergency services to act. Fire retardants save lives. The number of fires have dropped significantly over the past 40 years and a major contributor to the decline in fires and fire deaths since the 1970s was the development of a comprehensive set of fire-safety measures that include flame retardants. In 1988 the UK implemented the Furniture and Furnishing (Fire Safety) Regulations (FFR`s) following a major fire in the furnishings department of the Woolworths store in central Manchester. Tragically 10 people lost their lives in the fire. The regulations led to the use of flame retardants in the foam and on the back of the textiles used in furniture. The introduction of this legislation saved lives. On late 2009 The Department for Business, Innovation and Skills (BIS) published a report comparing the number of fires, injuries and deaths attributable to Furniture and Furnishings for the periods 1981-5 and 2002-7. Overall, in the period 2002-07, the analysis suggests that the FFRs account for:

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 phase of fire. They do not prevent charring or melting nor do they increase the heat resistance of a material. Flame retardants are also not effective when a fire is fully engaged. There is no universal additive for all plastics, rather each flame retardant is specific to a particular polymer and a particular flammability test. To understand how flame retardants work, it is necessary to understand how materials burn. When we see the flame of a burning object, we are actually seeing the combustion of flammable gases given off during its thermal decomposition. This process is call pyrolysis.

Flame Retardant are substances that can be chemically inserted into the polymer molecule or be physically blended in polymers after polymerization to suppress, reduce, delay or modify the propagation of a flame. There are several classes of flame retardants; Halogenated Hydrocarbons (Chlorine and Bromine containing Compounds and reactive flame retardants), Inorganic flame retardants ( Boron Compounds, Antimony oxides, Aluminium Hydroxide, molybdenum Compounds, zinc and magnesium oxides ), Phosphorous containing Compounds (Organic Phosphate Esters, Phosphates, halogenated phosphorus Compounds and inorganic phosphorus containing salts). Brominated Carbon Based Chlorinated Minerals Nitrogen Based Phosphorou

 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. Today, flame retardants are used predominantly in four major areas:  Electronics and Electrical Devices  Building and Construction Materials  Furnishings  Transportation (Airplanes, Trains, Automobiles)

Intumescent FR additive benefits:  Very robust fire safety and flame resistance performance.  One of the few systems that can use select polymer structures to actively participate in flammability reduction. Intumescent FR additive drawbacks:  Can have water pickup issues.  Can be expensive.  Can have low temperature limits that limit processing ranges. Intumescents are often used for applications requiring high levels of flame retardancy. Building and construction, firewall/firedoor barriers, aerospace, military, wire & cable, mass transport, etc. Novista supplies halogen-free flame retardants for PP, PE. PA6/PA66.

Halogenated FR additive benefits:  Very effective at lowering flammability in a wide range of polymers.  Provide good fire performance even after repeated recycling of polymer + FR resin. Halogenated FR additive drawbacks:  Always generate more smoke and carbon monoxide during burning.  Can be overwhelmed in high heat flux fires (little to no FR effectiveness).  Under regulatory scrutiny due to perceived environmental problems. Overall an old technology (since 1930s) but proven to work. OP422 OP1312 OP1314 OP1230 FP2200S

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 Flame Retardants (ex. Intumescents, Nanocomposites) - Operates in Condensed Phase by preventing fuel release and providing thermal insulation for underlying polymer. Novista Group supplies halogen-free flame retardant for PP, PE, PA6/PA66.

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.  A variety of flame retardants is necessary because materials that need to be made fireresistant are very different in their physical nature and chemical composition, so they behave differently during combustion.  The elements in flame retardants also react differently with fire. As a result, flame retardants have to be matched appropriately to each type of material. Flame retardants work to stop or delay fire, but, depending on their chemical makeup, they interact at different stages of the fire cycle.

 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, phosphorus or nitrogen.  It is important to note that flame retardants are not readily interchangeable. Their areas of application are often specific and substitution can be difficult.

 Flame retardants are a key component in reducing the devastating impact of fires on people, property and the environment.  They are added to treat potentially flammable materials, including textiles and plastics.  Flame retardant plastics are essential to devices we use every day, providing a valuable tool in fire prevention.  The term [flame retardant" refers to a function, not a family of chemicals. A variety of different chemicals, with different properties and structures, act as flame retardants and these chemicals are often combined for effectiveness.

IGNITION SOURCE • Prevent ignition • Possibly self-extinguish FLAME SPREAD (REACTION TO FIRE) • Slow down flame spread • Reduce heat release • Delay flash-over FIRE PENETRATION (RESISTANCE TO FIRE) • Prevent the collapse of structures, e. g. steel columns protected by intumescent coatings • Prevent fire moving to adjacent room or building compartment

• Fla me r • Flame retardants reduce the risk of ignition and fire spread of many plastic and textile materials w which results in more available escape time for occupants. • Time to flashover can increase from 5 minutes to 15 minutes which can make the difference between escape and fatalities. • Bear in mind that the escape time includes the time to discover the fire, alert other people, take the decision to call the fire brigade, take own actions to extinguish or take the decision to evacuate the building.
