Abstract
Described herein are methods for encapsulating a fiberglass substrate using a calendered film; along with products produced from same. The methods improve the efficiency of the manufacturing process and provide a product with improved performance characteristics.
Claims20
A method for preparing a flooring product comprising an encapsulated substrate comprising:
- providing a substrate having a first and a second major surface;
- applying a first calendered film to a first major surface of the substrate to form a composite, wherein at least a portion of the second major surface of the substrate remains exposed after the first calendered film is applied to the first major surface of the substrate;
- applying a foamable polymer formulation to said composite;
- and
- applying a second calendered film to said composite.

A method for preparing a multilayer composite comprising:
- providing a substrate having a first and a second major surface;
- applying a first calendered film to the first major surface of the substrate;
- applying a foamable polymer formulation to said first calendered film layer;
- wherein at least a portion of the substrate remains exposed after the first calendered film is applied to the first major surface of the substrate;
- and
- applying a second calendered film to the second major surface of the substrate.
3 more elements
A flooring product comprising:
- a foamable layer,
- a first melt processable film layer,
- an inorganic substrate,
- a second melt processable film layer, wherein said inorganic substrate is encapsulated by said first and second melt processable film layers.
