The present invention provides porous polymer coatings having adhesive and air flow resistive properties. The porous polymer coating comprises a polymeric foam having a void fraction of greater than about 15% and an air permeability greater than 3 cubic feet per minute per square foot as measured based on ASTM D737-04, wherein the polymeric foam comprises a clay and/or pigment optionally having an aspect ratio of about 2:1, 5:1, or 10:1 to about 20:1, 50:1, or 100:1. In some embodiments, the porous polymer coating comprises a chlorinated polymer and a fluorochemical.

The invention relates to a tile, in particular a carpet tile. The invention also relates to the use a tile according to the invention as floor tile, wall tile, or ceiling tile. The invention further relates to a tile covering consisting of a plurality of tiles according to the invention. The invention additionally relates to a carpet covering consisting of at least one carpet tile according to the invention.

Disclosed are a sound absorbing fabric with improved thermal insulation, and a method of manufacturing the same, wherein an inorganic aerogel powder and a thermosetting binder resin are impregnated into a non-woven fabric made of a heat-resistant fiber, wherein the inorganic aerogel powder has a surface modified by a surfactant to be uniformly mixed with and dispersed in a binder resin, thereby forming the sufficient number of micro cavities inside the non-woven fabric and increasing dispersibility of the inorganic aerogel powder, and thus heat resistance, sound absorbing and sound insulating properties, and thermal insulation properties can be significantly improved.

Provided is a composite thermal insulation sheet including an aerogel and a method for manufacturing method the same. The methods yield an ultra-thin aerogel composite sheet having characteristics of low dust, high strength and high thermal insulation, thereby having an increased applicability thereof to an electronic device.

The present invention provides porous polymer coatings having adhesive and air flow resistive properties. The porous polymer coating comprises a polymeric foam having a void fraction of greater than about 15% and an air permeability greater than 3 cubic feet per minute per square foot as measured based on ASTM D737-04.

A carpet for a sound reduction material is disclosed including: a non-permeable primary coating layer formed of polyethylene (PE) resin, being in contact with a lower surface of a fabric layer and having a basis weight of 200 to 300 g/m.sup.2; a permeable felt layer in contact with a lower surface of the primary coating layer and having a basis weight of 200 to 500 g/m.sup.2; and a non-permeable secondary coating layer formed of polyethylene (PE) resin or ethylene vinyl acetate (EVA), being in contact with a lower surface of the felt layer and having a basis weight of 200 to 1,000 g/m.sup.2. The carpet for a sound reduction material may thus have improved noise, vibration and harshness (NVH) performance, reduced total weight and improved stiffness.
