| Description | Fibrous glass is the name for a manufacturedfiber in which the fiber-forming substance is glass. Glassesare a class of materials made from silicon dioxide with oxides of various metals and other elements that solidify fromthe molten state without crystallization. Typically, glassfilaments .3 μm in diameter or glass “wool” with diameters down to 0.05 μm and length>1 μm. A fiber isconsidered to be a particle with a length-to-diameter ratioof 3:1 or greater. The volume of small diameter fiber production has not been determined. Fibers with diameters lessthan 1 μm are estimated to comprise less than 1% of thefibrous glass market. Specific gravity (H2O:1)=2.5.Hazard Identification (based on NFPA-704 M RatingSystem): Health 1, Flammability 0, Reactivity 0. Insolublein water. |

| Uses | Thermal, acoustic, and electrical insulation(coarse fibers in bats or sheets); decorative and utilityfabrics such as drapes, curtains, table linen, carpetbacking, tenting, etc.; tire cord as belt betweentread and carcass; filter medium; reinforced plastics;light transmission for communication signals;reinforcement of cement products for constructionuse. |
| Uses | Silica glass spheres are low density filler for coatings and plastics. Silica was used in synthesis of silicalite. Silica was also used to assist the catalytic growth of oxide and nitride nanowires. |
| Uses | Glasswool is used for thermal andacoustical insulation in construction and shipbuilding; for air filtration in furnaces and airconditioningsystems. |
| Definition | Generic name for a manufactured fiber in which the fiber-forming substance is glass (Federal TradeCommission). Noncombustible. |
| Definition | glass: Any noncrystalline solid; i.e. asolid in which the atoms are randomand have no long-range ordered pattern.Glasses are often regarded as supercooledliquids. Characteristicallythey have no definite melting point,but soften over a range of temperatures. The common glass used in windows,bottles, etc., is soda glass,which is made by heating a mixtureof lime (calcium oxide), soda (sodiumcarbonate), and sand (silicon(IV)oxide). It is a form of calcium silicate.Borosilicate glasses (e.g. Pyrex) aremade by incorporating some boronoxide, so that silicon atoms are replacedby boron atoms. They aretougher than soda glass and more resistantto temperature changes,hence their use in cooking utensilsand laboratory apparatus. Glasses forspecial purposes (e.g. optical glass)have other elements added (e.g. barium,lead). See also spin glass. |
| General Description | Silica is a naturally occurring material in minerals, flint and in some plants in crystalline phase. Silica used in industries is in synthetic form. Surface area, pore volume, pore size and particle size are independently controllable to some extent. The crystalline silica may be classified based on atmospheric pressure as: a. Quartz = 1143K b. Tridymite 1143 - 1743K c. Cristobalite = 1743, over 1973K it forms amorphous vitreous silica glass. |
| Hazard | A possible carcinogen. |
| Health Hazard | Glass fibers cause skin, eye, andupper respiratory tract irritation; althoughearlier classified by IARC to be a Group 2Bcarcinogen, possibly carcinogenic to humans,more recent evaluations indicate the humanrisk, if any, to be minimal. |
| Industrial uses | Fine flexible glass fibers made from glass are used for heat and sound insulation, fireproof textiles,acid-resistant fabrics, retainer mats for storage batteries, panel board, filters, and electrical insulating tape, cloth, and rope. Molten glass strings out easily into threadlike strands, and this spun glass was early used for ornamentalpurposes but the first long fibers of fairly uniformdiameter were made in England by spinningordinary molten glass on revolving drums. The standard glass fiber used in glass-reinforced plastics is a borosilicate type known asE-glass.Glass cloth of plain weave of either continuous fiber or staple fiber is much used forlaminated plastics. |
| Industrial uses | Glass, one of the oldest and most extensivelyused materials, is made from the most abundantof Earth’s natural resources — silica sand. Forcenturies considered as a decorative, fragilematerial suitable for only glazing and artobjects, today glass is produced in thousandsof compositions and grades for a wide range ofconsumer and industrial applications. |
| Industrial uses | The primary engineering benefits of glass fibersare their inorganic nature, which makesthem highly inert; high strength-to-weightratio; nonflammability; and resistance toheat, fungi, and rotting. Glass fibers are produced in both filamentand staple form. Their major engineering usesare thermal and/or acoustical insulation andas reinforcements, primarily for plastics. |
| Source | Kaolin and Ground silica are the major batch components in the production of fiberglass |
| Potential Exposure | The major uses of fibrous glass are inthermal, electrical, and acoustical insulation; weatherproof ing, plastic reinforcement; filtration media; and in structuraland textile materials. |
| First aid | If this chemical gets into the eyes, remove anycontact lenses at once and irrigate immediately for at least15 min, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts theskin, remove contaminated clothing and wash immediatelywith soap and water. If this chemical has been inhaled,remove from exposure, and move to fresh air. |
| storage | Color Code—Green: General storage may be used.Dust only: Color Code—Red: Flammability Hazard: Storein a flammable materials storage area. Prior to workingwith this chemical you should be trained on its proper handling and storage. |
| Waste Disposal | Fibrous glass waste and scrapshould be collected and disposed of in a manner which willminimize its dispersal into the atmosphere. Emphasisshould be placed on covering waste containers; proper stor age of materials; and collection of fibrous glass dust.Clean-up of fibrous glass dust should be performed using vacuum cleaners or wet cleaning methods. Dry sweepingshould not be performed. |
