Durable, liquid impermeable and moisture vapor permeable carpet pad

A carpet pad consisting essentially of:

• a cushion having an upper and lower surface thereon, and,
• a barrier film formed of a synthetic polymeric material directly bonded to the upper surface of the cushion,
• the carpet pad being simultaneously
• impermeable to liquid deposited onto the pad from above the barrier film, and
• permeable to moisture vapor at a moisture vapor transmission rate of at least 14.6 grams per square meter per twenty-four hours (14.6 g/m2/24 hours),
• the pad being sufficiently durable to maintain liquid impermeability after a Vetterman Drum Wear Test/Staining/Stain Cleaning Test of at least ten thousand cycles,
• whereby the carpet pad does not absorb liquid deposited onto the pad from above the upper surface of the barrier film and allows moisture from below the lower surface of the cushion to pass through the pad.

A carpet pad consisting essentially of:

• a cushion having an upper and lower surface thereon;
• a barrier film formed of a synthetic polymeric material;
• and
• a layer of adhesive material bonding the film to the upper surface of the cushion,
• the carpet pad being simultaneously
• impermeable to liquid deposited onto the pad from above the barrier film, and
• permeable to moisture vapor at a moisture vapor transmission rate of at least 14.6 grams per square meter per twenty-four hours (14.6 g/m2/24 hours),
• the pad being sufficiently durable to maintain liquid impermeability under a pressure of at least eight pounds per square inch (0.56 kg/m2) as measured by a Modified Mullen Bursting Strength Test,
• whereby the carpet pad does not absorb liquid deposited onto the pad from above the upper surface of the barrier film and allows moisture from below the lower surface of the cushion to pass through the pad.

A carpet pad comprising:

• a cushion having an upper and lower surface thereon, and,
• a barrier film formed of a synthetic polymeric material bonded to the upper surface of the cushion, the barrier film being free of any fibrous substrate laminated thereto,
• the carpet pad being simultaneously
• impermeable to liquid deposited onto the pad from above the barrier film, and
• permeable to moisture vapor transmission at a rate of at least 14.6 grams per square meter per twenty-four hours (14.6 g/m2/24 hours),
