Abstract
Embodiments of the present invention generally relate to a reinforced film for blast resistance protection and methods thereof. More specifically, embodiments of the present invention relate to a reinforced film comprising an elastomeric polymer laminate, and a scrim layer at least partially embedded in the elastomeric polymer laminate layer, wherein the reinforced film comprises a puncture resistance of at least five thousand pounds per square inch.
Claims46
A reinforced film, consisting essentially of:
- a first layer of an elastomeric polymer material;
- a second layer of an elastomeric polymer material;
- an adhesive layer;
- and
- a scrim layer of a scrim material,
- wherein the reinforced film is arranged in the order of the first layer, the scrim layer, the second layer, and the adhesive layer, and
- wherein the reinforced film has a puncture resistance in a range between about 3000 psi and about 25000 psi
- wherein the adhesive layer comprises a pressure sensitive adhesive and a release liner associated therewith.
(canceled)
A reinforced film, consisting essentially of:
- a) an elastomeric polymer layer comprising a polyurethane;
- b) an aramid-based scrim layer associated with the elastomeric polymer material layer;
- c) a pressure sensitive adhesive layer associated with the elastomeric polymer material;
- and
- d) a release liner layer,
- wherein the reinforced film is arranged in the order of the release liner layer, the pressure sensitive adhesive layer, the elastomeric polymer layer, and the scrim layer.
(canceled)
A multi-layer film consisting essentially of,
- (a) an elastomeric layer having a thickness of between about 2 mils and about 75 mils;
- (b) a fibrous layer comprising a plurality of fibers of between about 1000 to about 4000 denier;
- and
- (c) an adhesive layer, wherein
- the multi-layer film has a puncture resistance of between 3,000 psi and 25,000 psi as determined according to ASTM D-3759, the multi-layer film has a first surface comprising the adhesive layer, and the multilayer film is configured to be a roll.
(canceled)
A reinforcement film, consisting essentially of:
- a polymeric layer, a scrim layer, an adhesive layer, and a removable release liner, wherein the film is arranged in the order of the scrim layer, the polymeric layer, the adhesive layer, and the removable release liner,
- wherein the film has a puncture resistance after the removable release liner is removed to expose the adhesive layer of between 3,000 psi and 25,000 psi as determined according to ASTM D-3759 and wherein the reinforced film is configured to be rolls.
A multi-layer film, consisting essentially of:
- (a) at least one fibrous scrim layer having a first side and a second side and comprising a plurality of either fiber bundles, fiber strands or a mixture of fiber bundles and fiber strands, the fibers being between about 1,000 to about 10,000 denier, the fibrous scrim layer having a plurality of openings between the fiber bundles or strands;
- (b) at least one elastomeric layer associated with each side of the fibrous scrim layer, each elastomeric layer having a thickness of between about 2 mils and about 75 mils;
- and,
- (c) a pressure sensitive adhesive layer,
- wherein the multi-layer film has a puncture resistance of between 3,000 psi and 25,000 psi as determined according to ASTM D-3759 and is configured as a roll.
