Abstract
An aqueous size composition for glass fibers is disclosed which includes a thermoplastic polymer resin powder, a coupling agent, and fugitive processing aids, such as binders or film formers. The composition is applied to the glass fiber surfaces during the fiber forming process. A fugitive rheology modifier material may be added to the size composition. One embodiment of the composition includes a polyethylene oxide binder material and a polyphenylene sulfide thermoplastic polymer resin.
