Insulation Laminated 4mm Bakelite Sheet
Description of Orange Bakelite Sheet:
Making Bakelite was a multi-stage process. It began with the heating of phenol and formaldehyde in the presence of a catalyst such as 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 still be softened by heat. Sustained heating resulted in an "insoluble hard gum". However, the high temperatures required to create this tended to cause violent foaming of the mixture, which resulted in the cooled material being porous and breakable. Baekeland's innovative step was to put his "last condensation product" into an egg-shaped "Bakelizer". By heating it under pressure, at about 150 °C (300 °F), Baekeland was able to suppress the foaming that would otherwise occur. The resulting substance was extremely hard and 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, under high 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 preformed partially cured slugs, increasing the speed of the casting. Thermosetting resins such as Bakelite required heat and pressure during the molding cycle, but could be removed from the molding process without being cooled, again making the molding process faster. Also, because of the smooth polished surface that resulted, Bakelite objects required less finishing. Millions of parts could be duplicated quickly and relatively cheaply.
Key Feature of Orange Bakelite Sheet:
Resistant to heat, scratches, and destructive solventsResistant to electricityPrized for its low conductivityIt is not flexible
Applications of Orange Bakelite Sheet:
particularly suitable for the emerging electrical and automobile industriesin the electrical industrywas used widely for machine partsBakelite was used for game pieces like chessmen, poker chipswas used in a variety of wartime equipment including pilot's goggles and field telephonesin ablative heat shields
