Methods for fabricating rubber-based elastomeric materials are disclosed. In an embodiment, a method for fabricating a rubber-based elastomeric glove includes milling diene rubber to form first and second milled diene rubber portions; forming a first mixture by mixing a silica reinforcing component and a first antiozonant wax with the first milled diene rubber portion; forming a second mixture by mixing a second antiozonant wax with the second milled diene rubber portion; mixing the first mixture, the second mixture, and a solvent to form a viscous solution; and dipping a glove mold into the viscous solution for a selected number of dips, and evaporating the solvent from the glove mold between dips to form the rubber-based elastomeric glove, wherein the elastomeric glove has a thickness of at least about 30 mils, and wherein the elastomeric glove exhibits a flexural modulus of less than about 0.06 MPa.

An acoustical ceiling panel is provided having a core with a front face and a back face composed of air laid mineral fibers and an aqueous binder. The aqueous binder includes a first component in the form of one or more carbohydrates, and a second component in the form of one or more compounds selected from sulfamic acid, derivatives of sulfamic acid, and any salts thereof, ammonia and hypophosphorous acid. A formaldehyde-free first fleece having a thickness is secured to the front face of the core by powdered adhesive and a formaldehyde-free second fleece having a thickness is secured to the back face of the core by the aqueous binder, with the thickness of the first fleece being greater than the thickness of the second fleece. Paint is applied to the first fleece. The acoustical ceiling panel has formaldehyde emissions of below 8 g/m.sup.2/h of formaldehyde, preferably below 5 g/m.sup.2/h, most preferably below 3 g/m.sup.2/h, in accordance with ISO 16000 for testing aldehyde emissions.

The present invention relates to a formaldehyde-free binder composition for mineral fibres comprising: at least one phenol and/or quinone containing compound, at least one protein, at least one fatty acid ester of glycerol.

The present invention concerns a method of producing a moulded mineral wool insulation product, said method comprising the steps of providing a mixture by mixing mineral fibres with a binder composition, and providing said mixture in a mould form, and then curing the binder, wherein the binder composition comprises at least one hydrocolloid, and then removing the moulded product from the mould form.

Elastomeric materials and articles of manufacture produced using elastomeric materials are disclosed. In an embodiment, a rubber-based elastomeric material includes a diene rubber component, a reinforcing component, and a wax component. The rubber-based elastomeric material is provided in the form of a film having a thickness of at least about 30 mils. The film exhibits a flexural modulus of less than about 0.06 MPa.
