Patent

CA 2079409

There is disclosed novel glass fiber particularly useful for preparing formed insulating articles having on the surface of the fibers an amorphous aluminum phosphate polymer wherein the polymer resiliently tacks the glass fibers together so as to provide regain of shape after deformation of the fibers as by compression. Also disclosed is a process for preparing glass fiber articles wherein the fibers are contacted with an ionic polymer which is then dehydrated to form an amorphous non-hygroscopic polymer.

Nouvelle fibre de verre, particulièrement utile pour la préparation d'articles isolants mis en forme; les fibres portent à leur surface un polymère de phosphate d'aluminium amorphe; ce polymère retient les fibres ensemble leur permettant de retrouver leur forme après une déformation, comme par compression. L'invention présente également une méthode pour la préparation de fibres de verre, où celles-ci sont mises en contact avec un polymère ionique, lequel est ensuite déshydraté pour former un polymère amorphe non hygroscopique.
