Abstract
The invention provides a film that includes chloride-containing vinyl polymer and a stabilizer component, wherein the film has a 96-hour Volatile Organic Compound Emission Factor of no more than 1,000 μg/m2/hour. The invention also provides a film that includes vinyl chloride polymer and a stabilizer component comprising a stabilizer and a diluent, wherein the diluent comprises a monohydric alcohol having 12 or more carbon atoms. Also described are methods of stabilizing a chloride-containing vinyl polymer film, a system for providing a low VOC releasing chloride containing vinyl polymer film, and methods of printing a chloride-containing vinyl polymer film.
Claims15
A flexible polyvinyl chloride film comprising:
- a. chloride-containing vinyl polymer;
- b. plasticizer in an amount in the range of 30 to 100 parts-per-hundred parts resin;
- c. a stabilizer component comprising a stabilizer and a diluent, wherein the diluent comprises a monohyciric alcohol having 12 or more carbon atoms that is present in an amount in the range of 10–50% by weight of the stabilizer component, and wherein the stabilizer and diluent are each selected such that, when the stabilizer component is combined with the chloride-containing vinyl polymer to form a flint, the film has a 96-hour Volatile Organic Compound Emission Factor of no more than 1,000 μg/m2/hour and
- d. a backing attached to the film.
A method of stabilizing a flexible chloride-containing vinyl polymer film comprising steps of:
- a. providing a chloride-containing vinyl polymer including plasticizer, the plasticizer being present in an amount in the range of 30 to 100 parts-per-hundred parts resin, and
- b. incorporating into the chloride-containing vinyl polymer a stabilizer component in an amount effective to stabilize the chloride-containing vinyl polymer, wherein the stabilizer component comprises a stabilizer and a diluent, wherein the diluent comprises a monohydric alcohol having 12 or more carbon atoms, and wherein the stabilizer and diluent are each selected such that, when the stabilizer component is combined with a vinyl chloride polymer to form a film, the vinyl chloride polymer film exhibits a 96-hour Volatile Organic Compound Emission Factor of 1,000 μg/m2/hour or less;
- c. forming the chloride-containing vinyl polymer with stabilizer component into a flexible film;
- and
- d. attaching a backing to the film.
