The present invention is directed to a high temperature low emitting mineral fiber product which is suitable as thermal insulation.

Embodiments generally relate to devices and methods for production of fibers and threads for use in electronic device manufacturing. Described here, fibers can be produced and manipulated using a dual-surfaced sizing material. The dual-surfaced sizing material has a surface which binds a fiber and a surface which binds a resin. Thus, the dual-surfaced sizing material can be left attached to the fibers without adversely affecting the resin binding in later production steps.

The invention relates to a fibrous mat facer for preparing a gypsum board, to a gypsum board comprising said mat facer and to a system comprising said gypsum board. The fibrous mat comprises at least one ply of a non-woven fabric, and a binder composition, wherein the binder composition represents from 10 to 40 wt % of the total weight of the mat. The binder composition comprises a copolymer comprising a co-monomer unit of a vinyl ester of an alpha branched aliphatic monocarboxylic acid, said copolymer being present in an amount from 25 to 100 wt % of the binder composition weight.

A tool provided that individually creates three-dimensional structural elements which are sequentially positioned into formation of a shaped object.

An optical fiber comprises a glass fiber, and a coating resin layer having a primary resin layer and a secondary resin layer, wherein the primary resin layer consists of a cured resin composition containing an oligomer, a monomer and a photopolymerization initiator, the oligomer is a reaction product of a specific polyol compound, a polyisocyanate compound, and a hydroxyl group-containing acrylate compound, the photopolymerization initiator includes 2,4,6-trimethylbenzoyldiphenyl phosphine and 1-hydroxycyclohexyl phenyl ketone at a mass ratio of 5:1 to 1:1, and a content of 2,4,6-trimethylbenzoyldiphenyl phosphine in the resin composition is 1.5 to 2.5% by mass.

A fibre structure formed from dissolvable glass fibres is provided, the dissolvable glass fibres being formed from one or more boron compounds and one or more alkali compounds. The dissolvable glass can be formed into filaments, rovings and staple fibres of varying composition, length and diameter dependent on functionality and purpose. A mixture of chemicals components are heated, melted and then drawn or extruded into dissolvable filaments, rovings and staple fibres for use in a fibre-reinforced composite part or as a preservative in the internal and surface treatment of solid wood and engineered composite panels. A water-soluble surface coating may be applied to adjust dissolution rate and facilitate binding into an air-laid nonwoven mat or incorporation into other matrices.

Biocides for bio-based binder compositions are disclosed. Bio-based binders include those having a nutrient source such as carbohydrate, protein or fat, which can serve as an energy source for organisms to grow in areas that contact binder. Principal areas that contact bio-based binder in a fiberglass insulation manufacturing process include the raw ingredients, the binder chemicals, the prepared binder dispersions, the forming hood and related equipment, the final insulation product and, importantly, the cleaning systems and washwater arising from cleaning the manufacturing equipment and/or forming the product. Frequently the washwater is stored until re-cycled for re-use. Storage may take place in tanks, towers, vats and even outdoor reservoirs, all of which may harbor the growth of unwanted organisms, for which a biocide is desirable.

The present invention relates to sizing compositions, glass fibers at least partially coated with sizing compositions, and glass fiber reinforced composite materials. In one embodiment, a sizing composition comprises at least one maleic anhydride copolymer, at least one coupling agent, and a reaction product of an alkoxylated amine and a polycarboxylic acid, which is further reacted with an epoxy compound.
