With a total of three patents to his name, Sharma has developed innovative methods that enhance the functionality and application of microporous materials.
Latest Patents
One of Sharma's latest patents is a high-speed method of making microporous film products. This invention allows for the production of microporous film products that are permeable to moisture vapor while acting as barriers to liquid. The method operates at impressive speeds ranging from above 500 feet per minute to about 1200 feet per minute. The composition involves thermoplastic polymers that are melt blended to include approximately 35% to 45% by weight of linear low-density polyethylene, 3% to 10% by weight of low-density polyethylene, 40% to 55% by weight of calcium carbonate filler particles, and 2% to 6% by weight of a triblock polymer of styrene.
Another notable patent is the method of making a cloth-like microporous laminate of a nonwoven fibrous web. This innovative process involves the lamination of a microporous-formable film composition with a nonwoven fibrous web, followed by incremental stretching to create a cloth-like microporous laminate. This laminate possesses air and moisture vapor permeabilities while serving as a barrier to liquid passage. Such materials are particularly beneficial in the fabrication of garments, including baby diapers, training pants, and catamenial pads, where both moisture vapor transmission and liquid barrier properties are essential.
