|20120282432||FLAME RETARDANT PVC PLASTISOL COMPOSITIONS USEFUL AS COATINGS, ADHESIVES AND BACKINGS - This invention relates to flame retardant compositions which have utility for coating substrates. In particular, this invention relates to flame-retardant plastisol compositions based on polyvinylchloride (PVC), plasticizer and zeolites that are useful as coatings, backings and adhesives for flexible substrates such as woven and non-woven fabrics, carpets and the like.||11-08-2012|
|20110065845||HALOGEN-FREE FIRE RETARDANT COMPOSITIONS - A chlorine- and bromine-free fire retardant composition based on organic polymer and zeolite is disclosed.||03-17-2011|
|20100152352||SUBSTRATES COATED WITH FLAME RETARDANT COMPOSITIONS BASED ON ORGANIC POLYMERS AND ZEOLITES - Substrates, which may be either flexible or rigid, are coated with a flame retardant composition containing an organic polymer, a filler and a zeolite. Good flame retardant properties are obtained even where the composition contains low levels of conventional flame retardant additives such as antimony compounds, brominated compounds and zinc compounds. The flame retardant composition may also be used to adhere different substrates together.||06-17-2010|
|20100048780||PREVENTION OF COLOR FORMATION IN POLYOLEFINS - Compositions that have been stabilized to prevent gas fading are disclosed. The compositions comprise a polyolefin, a phenolic antioxidant, and at least of either a phosphite stabilizer or a hydroxyl amine stabilizer. Unlike previous stabilizer systems, which have used “phenolic free” polymers, the inventive stabilizer system can stabilize polyolefins against gas fading in the presence of a phenolic antioxidant.||02-25-2010|
|20090137174||FLAME-RETARDANT POLYMERIC COMPOSITIONS - A flame-retarded polymeric composition is provided which contains a) a polyolefin, b) a mixture of a halogenated flame-retardant and zeolite, and optionally c) a synergist. Also provided is a flame and smoke-retarded polymeric composition containing a polyolefin and a mixture of a hydrated metal oxide and zeolite.||05-28-2009|
|20090022462||FIRE RESISTANT JACKET COMPOSITION FOR ELECTRICAL COAXIAL AND FIBER OPTIC CABLE - Zeolite-containing polyvinyl chloride containing compositions that are useful as the insulation for plenum cables are disclosed. A zeolite, either natural or synthetic, can satisfactorily replace either part or all of the molybdenum compound, particularly ammonium octamolybdate, in low smoke polyvinyl chloride based plenum compositions. Ion-exchanged zeolites, such as the zinc ion-exchanged zeolite can also be used. Zeolites are especially useful in lead-free Low Smoke PVC compositions. Because the cost of zeolite is only a fraction of the cost of the molybdenum compounds currently used in plenum cable compositions, this will dramatically reduce the cost of these materials.||01-22-2009|
