Plasticized polyvinyl chloride resin composition containing molybdenum flame retardant and antimony compound smoke suppressant agent

Abstract: A flame resistant and smoke suppressed plasticized polyvinyl chloride polymer containing from about 20 to about 100 parts per hundred resin (phr) of a plasticizer comprising an ester-type primary plasticizer in combination with a controlled amount of a chlorinated paraffin or organic phosphate ester secondary plasticizer and an effective amount of a flame retardant and smoke suppressant agent comprising inorganic molybdenum compounds, such as molybdenum oxides and metal molybdates. In accordance with a preferred embodiment, the flame retardant and smoke suppressant agent further includes a controlled effective amount of antimony oxide in combination with the molybdenum compound imparting synergistic flame retardancy and smoke suppressing characteristics to the plasticized polyvinyl chloride resin formulation.

Polyvinyl chloride compositions containing trizinc dimolybdate monohydrate and zinc phosphite for smoke suppression

Abstract: A smoke suppressed rigid or plasticized polyvinyl chloride polymer composition contains a polyvinyl chloride polymer and a small but effective amount of a smoke suppressant consisting essentially of a mixture of Zn 3 Mo 2 O 9 ·H 2 O and ZnHPO 3 , in an atomic ratio of Mo to P of about 0.5:1 to about 2.0:1, to impart smoke suppression to the polymer composition.

Advances in the use of molybdenum compounds as smoke suppressants for PVC

Abstract: Molybdenum-based compounds are effective smoke suppressants for rigid and flexible polyvinyl chloride formulations, both unfilled and filled with calcium carbonate and alumina trihydrate. These compounds, two of which are new compounds based on zinc molybdate with or without a phosphite synergist, are useful as is or extended onto core materials such as clay or talc. The addition of molybdenum-containing additives to flexible PVCs containing antimony trioxide usually raises the oxygen index and thus improves flame retardancy. Tests indicate that molybdenum acts as a flame and smoke suppressant in the solid phase.

Ester-plasticized polyvinyl chloride resin composition containing molybdenum flame retardant and smoke suppressant agent

Abstract: A flame resistant and smoke suppressed plasticized polyvinyl chloride polymer containing from about 20 to about 80 parts per hundred resin (phr) of an ester-type plasticizer and an effective amount of a flame retardant and smoke suppressant agent comprising an inorganic molybdenum compound such as molybdenum oxides and metal molybdates. In accordance with a preferred embodiment, the flame retardant and smoke suppressant agent further includes a controlled effective amount of an antimony compound such as antimony oxide in combination with the molybdenum compound imparting synergistic flame retardancy and smoke suppressing characteristics to the plasticized polyvinyl chloride resin formulation.

Thermoplastic planks and methods for making the same

Abstract: A thermoplastic laminate plank is described wherein the thermoplastic laminate plank comprises a core, a print layer, and optionally an overlay. The core comprises at least one thermoplastic material and has a top surface and bottom surface wherein a print layer is affixed to the top surface of the core and an overlay layer is affixed to the top surface of the print layer. Optionally, an underlay layer can be located and affixed between the bottom surface of the print layer and the top surface of the core. In addition, a method of making the thermoplastic laminate plank is further described which involves extruding at least one thermoplastic material into the shape of the core and affixing a laminate on the core, wherein the laminate comprises an overlay affixed to the top surface of the print layer and optionally an underlay layer affixed to the bottom surface of the print layer.

Floor panel with sealing means

Abstract: Floor panels and floor elements therefore are made of sheet-shaped cores which before application of the surface of the floor panels are formed with sealing means for counteracting changes in the properties of the floor panels caused by moisture.

Flame retardant low smoke poly(vinyl chloride) thermoplastic composition

Abstract: A flame retardant low smoke PVC-based thermoplastic composition for use in wire insulation and cable jacketing is disclosed. The composition includes poly(vinyl chloride), chlorinated poly(vinyl chloride), molybdenum oxide, alumina trihydrate, and isodecyl diphenyl phosphate as its primary ingredients, and additionally includes at least one heat stabilizer, at least one antioxidant, at least one lubricant, and at least one plasticizer besides the isodecyl diphenyl phosphate. It may also include antimony oxide, fillers, and chlorinated paraffins. The composition has excellent flame retardancy and produces only a relatively small amount of light-colored smoke when burned.
