Abstract: The use of thermosetting binder systems in the manufacture of glass fibers and composites manufactured from glass fiber is disclosed, and in particular, thermosetting binder resins derived from renewable resources that are useful as replacements for formaldehyde-based binders in non-woven fiberglass goods.

Abstract: The present invention relates to an air filtration media made from very fine glass fibers having an average fiber diameter within a range from 3×10?5 to 2×10?4 inches, with the media comprising a formaldehyde-free binding agent comprised of a polycarboxy polymer and a polyol to bind the glass fibers together.

Abstract: Provided is a fiberglass binder composition which comprises a polycarboxy polymer, a polyol and a fluorinated polymer. The binder also preferably includes a catalyst which is an alkali metal salt of a phosphorus-containing organic acid. The resultant binder provides minimal processing difficulties and a fiberglass product which exhibits minimal water absorption.

Abstract: Provided is a fiberglass binder composition which comprises a polycarboxy polymer modified with a fatty acid, and a polyol. The binder also preferably includes a catalyst which is an alkali metal salt of a phosphorus-containing organic acid. The resultant binder provides minimal processing difficulties and a fiberglass product which exhibits minimal water absorption.

Abstract: A nonwoven web of polymer fibers bonded with from about 5 to about 30 wt. percent of a cured binder composition, based on the weight of the web or mat. The web is a spunbonded web of polymer, such as polyester, fibers bound with a binder containing one or more formaldehyde fortified polymer resins that normally emit substantial formaldehyde at high temperatures, but in this invention the binder also contains up to about 7.5 wt. percent of a bisulphite compound, preferably ammonium bisulphite. This binder is applied in latex form to the fibrous web after the fibers are made and collected in a known manner and then the wet web is dried and heated to cure the binder in a known manner. The resultant nonwoven webs have good hot strength and low formaldehyde emissions and reasonable costs, something not heretofore attainable with these types of formaldehyde containing binders. The webs of the present invention are useful for making various roofing products such as built up roofing products and for other uses.
