3025 4x8 Phenolic Laminated wood sheet OEM ODM Bakelite Sheet With Good PriceDescription of Bakelite Sheet:Making Bakelite was a multi-stage process. It began with the heating of phenol and formaldehyde in the presence of a catalyst suchas hydrochloric acid, zinc chloride, or the base ammonia. This created a liquid condensation product, referred to as Bakelite A,which was soluble in alcohol, acetone, or additional phenol. Heated further, the product became partially soluble and could stillbe softened by heat. Sustained heating resulted in an "insoluble hard gum". However, the high temperatures required to create thistended to cause violent foaming of the mixture, which resulted in the cooled material being porous and breakable. Baekeland'sinnovative step was to put his "last condensation product" into an egg-shaped "Bakelizer". By heating it under pressure, at about150 °C (300 °F), Baekeland was able to suppress the foaming that would otherwise occur. The resulting substance was extremely hardand both infusible and insoluble.Compression Molding:Molded Bakelite forms in a condensation reaction of phenol and formaldehyde, with wood flour or asbestos fiber as a filler, underhigh pressure and heat in a time frame of a few minutes of curing. The result is a hard plastic material. Bakelite's molding process had a number of advantages. Bakelite resin could be provided either as powder, or as preformedpartially cured slugs, increasing the speed of the casting. Thermosetting resins such as Bakelite required heat and pressureduring the molding cycle, but could be removed from the molding process without being cooled, again making the molding processfaster. Also, because of the smooth polished surface that resulted, Bakelite objects required less finishing. Millions of partscould be duplicated quickly and relatively cheaply.Key Feature of Orange Bakelite Sheet: * Resistant to heat, scratches, and destructive solvents * Resistant to electricity * Prized for its low conductivity * It is not flexibleApplications of Orange Bakelite Sheet: * particularly suitable for the emerging electrical and automobile industries * in the electrical industry * was used widely for machine parts * Bakelite was used for game pieces like chessmen, poker chips * was used in a variety of wartime equipment including pilot's goggles and field telephones * in ablative heat shieldsItemsUnitsValue(A/B)Flexural strength perpendicularto laminationsMPa≥100Compression strength perpendicular to laminationsMPa≥245Bomding strengthN≥5400dielectric strength perpendicular to laminations(in 90 ±2°c transformer oil, 1mm in Thickness)KV/mm≥0.82breakdom voltage parallelto laminations (in 90 ±2°c CTransformer oil)KV≥1permittivity(1MHz)—≤5.5Dissipation factor (1MHz)—≤0.04Insulation resistance afterimpregnated in waterΩ1.0*106Water absorptionmg206Tensile strengthMPa≥98Impact strengthKJ/m28.8Temperature index(short time)—120Shenzhen Xiongyihua Plastic Insulation Limited Shenzhen Xiongyihua Plastic Insulation Limited was established in 2006 in Shenzhen, after more than decades of continuous efforts, has developed into a professional integrated manufacturer of specializes in production and development Engineering Plastic and Insulation Plastic ,is the most complete varieties.
