  3. 3. Flame Retardant adhesive Tapes are generally meant for ElectricalInsulation applications.These tapes are based on substrates like , Fabrics ( Cotton orsynthetics) , Polyester Film, and even paper.These types are tapes are made by coating a flame retardant waterproof coating on one side and a Flame retardant adhesive on theother.The selection of a right quality of substrate , Polymer for waterproof coating and Adhesive , and a very serious choice of Flameretardant additives both for Adhesive as well as Water proofcoating, to is the key , for high quality Flame retardant Tapes. TheFlame retardant used for Adhesive , has to be totally compatiblewith , the type of PS Adhesive used , in no case the additive couldinterfere with the Adhesive performance and properties.Hence selection of Flame retardant is very crucial , and we have tounderstand their role properly. 07-04-2013 3
  4. 4. Frequently asked questions about Flame retardancyQ: What are flame retardants?A: The Highly important ingredient in reducing the Fire risks to people,property and the environment , is a flame retardant additive. They arecompounded into to flammable materials, like textiles , paper and plastics. The term “flame retardant” refers to a function, not a family of chemicals.There is a big choice of chemicals , that are added in combination , for mosteffective results. These chemicals may have A variety of different propertiesand structures , and the effect.Q: What are the most common elements in flame retardants?A: Bromine, phosphorus, nitrogen and chlorine are commonly used in flameretardants. Inorganic compounds are also used in flame retardants, eitheralone or as part of a flame retardant system in combination with bromine,phosphorus or nitrogen.07-04-2013 4
  5. 5. Combustion Cycle Substrate07-04-2013 5
  6. 6. The fire cycle:1. Initial ignition source could be heat, incandescent material, a small flame, or Static discharge2. This causes the material to catch fire , and burns , to decompose (pyrolysis), releasing flammable gases.3. solid materials will not break down into gases, but enter into a condensed phase. During this phase, they self-extinguish, after charring . This is because the material creates a carbonated barrier between the flame and the material beneath .4. In the gas phase, flammable gases released from the material are mixed with oxygen from the air. In the combustion zone, or the burning phase, fuel, oxygen and free radicals combine to create chemical reactions that cause visible flames to appear. The fire then becomes self-sustaining because, as it continues to burn the material, more flammable gases are released, feeding the combustion process.07-04-2013 6

  11. 11. Q: Why are flame retardants important to use?A: Flame retardants is essential to1. stopping or slowing the spread of fire.2. to prevent ignition.3. reduce the spread of fireThe use of flame retardants is especially important todaybecause modern homes, with the increase in electronic productsalone,present a greater risk of fire dangers.Their benefits are often noticed only when they are not present.07-04-2013 11
  12. 12. Q: Are all flame retardants the same?A: A variety of flame retardants is necessary because theelements in flame retardants react differently with fire.In addition, materials that need to be made fire-resistant arevery different in their physical nature and chemical composition,and they behave differently during combustion.As a result, chemical manufacturers have developed differentflame-retardant chemistries to suit different products to renderthem fire-resistant and allow them to retain their intendedfunctionality and performance standards.07-04-2013 12

  14. 14. Flame Retardant tapesThe Precoat and the Adhesive require to meet the followingcriteria:1. Resist burning,2. Retain joint integrity at high temperatures,3. Produce minimal smoke, and4. Release negligible toxic materials when heated beyond its decomposition temperature. Achieving these goals is not easy for the adhesive formulator, especially recognizing that the adhesive system must also provide the usual requirements of low cost, high strength, durability, and easy application. 07-04-2013 14

  18. 18. Halogenated vs. Non-HalogenatedDespite significant advances in non-halogen flame retardantsystems and safety and environmental concerns over olderhalogen based additives, the use of non-halogenated flameretardants seems to be very much dependent on region. Safety andenvironmental concerns about halogenated flame retardants havebeen primarily a European phenomena. Although no newscientific evidence of dangers from these products has emerged,the pressure to find alternatives has not decreased. Figure 1shows the 2005 consumption of flame retardants in Europe whichamounted to 463,800 metric tons.07-04-2013 18

  20. 20. Manufacture of Flame Retardant Pre Coat for fabrics With a strong fire , any fabric based tape will burn. While thermoplastic based precoats melt readily with heat, thermosetting and reactive coatings can survive much higher temperatures, but are still not "flame retardant" on their own. Polyimides, which is costly , resist only 400°C, a temperature that fires can exceed easily. A fire effectively has four stages - initial, growth, steady state and decay, with corresponding temperatures. In designing a fire-retardant precoat, formulators must put their efforts on delivering temperature resistance on the right fire stage for their applications.07-04-2013 20
  21. 21. Coating Method most suitable for fabrics , with Flame retardantproof coating , is Floating Knife system. The details of the sameare shown in the figure below. FLOATING KNIFE METHOD FOR HIGH VISCOSITY COATINGS07-04-2013 21

  24. 24. There are many ways to establish how fire-retardant an adhesive is, including the well-known Underwriters Laboratory UL-94 test for resistance to burning. Other important tests include assessments for toxicity and smoke generation. Selecting Adhesive Polymers for Fire Retardancy Natural Rubber , Synthetic Rubber’s like , SBR , Butyl, Nitrile and Neoprene( Poly Chloroprene ) are the polymers generally used for PS Adhesive compounding with suitable Flame retardants.07-04-2013 24
