Antistat for glass fiber manufacture, enables trouble free spinning of filaments from spinnerets to take off rollers. 

The composition of the sizing or coating used in glass fiber manufacture is very important to the final mechanical properties of glass-reinforced polypropylene... 

For over 35 years, commercial glass fiber manufacture has exhibited continuous growth in volvune to meet increasing demands in the market place for short glass fiber reinforced (SGFR) composites in many... 

Glass fiber manufacturers introduce a sizing package [4,5] in aqueous medium which generally consists of the following key ingredients ... 

The hand lay-up or spray-up process, used universally for the production of laminar composites incorporating glass fiber reinforcement, is most efficient for the manufacture of large parts, such as boats, bathtubs, tanks, architectural shapes, and recreational accessories. Resins intended for spray-up processes are usually modified with thixotropic additives, such as fumed siHca (1%), to reduce the risk of drainage when appHed over large vertical mold surfaces. Molds are also made from ERP for short-mn products usually surfaced with a tooling gel coat to provide consistent surface quaHty and appearance. 

Introduced successfully for tires in 1967, glass fibers had properties that made them very attractive for use in tires (5,8). The britdeness of glass fibers, however, imposed some limitations on the final tine cord properties because of the requirement that each fiber be individually coated with a mbbery adhesive to avoid interfilament damage during fabrication and use. This additional treatment step is introduced at the fiber manufacturing stage. For several years fiber glass was used extensively in bias-belted and radial tires, but was ultimately replaced by steel belts in radial tires. 

The flow along the membranes also improves the mass transport there, and the separators between the membranes are constmcted to provide good flow distribution and mixing on the membrane surfaces. Membrane sizes are often about 0.5 x 1 m, spaced about 1 mm apart. Many types of polymers are used to manufacture these ion-exchange-selective membranes, which are often reiaforced by strong fabrics made of other polymers or glass fibers. 

Fibrous Glass. Fibrous glass is manufactured in two different forms, very fine intermingled fibers called insulation fibrous glass for insulation and fine but coarser fibers called continuous or textile fibers for reinforcement and other textile appHcations. Both products have constmction related apphcations.
