Bakelite is NOT a form of frozen formaldehyde. It worked on the same principle as early record players. The material is often called Bakelite . Consider the weight of a piece of plastic jewelry. You will often notice the heavier feel of Bakelite. Hold another type of plastic you have identified in one hand, and a piece you know to be Bakelite of approximately the same size in the other. These layers of laminations are usually of cellulose paper, cotton fabrics, synthetic yarn fabrics, glass fabrics or unwoven fabrics. This is an early example of a Dictaphone housed in a Bakelite casing. Bakelite Resin PF0224SP is a powdered phenolic novolac resin with hexamethylenetetramine used in bonded abrasive applications. An example of typical color change is shown in Fig. More importantly, Catalin was transparent allowing the use of color or mixture of colors during the manufacturing process. Bakelite was the first truly synthetic, as well as the first commercially produced, synthetic resin. The process of creating Bakelite resin is irreversible: it can't be reverted to its original components! Phenol formaldehyde resins (PF) or phenolic resins are synthetic polymers obtained by the reaction of phenol or substituted phenol with formaldehyde.Used as the basis for Bakelite, PFs were the first commercial synthetic resins (plastics).They have been widely used for the production of molded products including billiard balls, laboratory countertops, and as coatings and adhesives. Bakelite is a thermosetting phenol formaldehyde resin, formed from a condensation reaction of phenol with formaldehyde. Known as a cast phenol formaldehyde resin, Catalin, created in 1927, is a thermosetting polymer not unlike Bakelite, except the production is in two stages, where Bakelite requires more of a multistage curing process. Bakelite feels heavier when compared to some other types of plastics, like celluloid as one example. Celluloid was also very flammable giving Bakelite another advantage. Bakelite Phenolic sheet is a hard, dense material made by applying heat and pressure to layers of paper or glass cloth impregnated with synthetic resin. 6. A needle etched grooves from sound vibrations onto a wax cylinder which a secretary would later play back and listen to. All true Bakelite, regardless of surface color (Figs. Phenolic resins (Phenoplasts) are synthetic thermosetting resins invented by Dr. Leo Baekeland in 1907. Phenoplasts are some of the oldest synthetic thermosetting polymers and continue to be prominent resins with an impressive worldwide volume … Melting is a process whereby a collection of atoms/molecules that are held together by weak forces are provided sufficient energy so that the individual molecules can separate from each other. Normal oxidation provides a valuable clue whether a suspected piece is true Bakelite (phenolic resin) or a look-alike material. The resin is known for behind highly water resistant, and has a flash-point much, MUCH higher than the temperature of boiling water, not to mention the human body. Bakelite is a thermosetting resin—that is, once molded, it retains its shape even if heated or subjected to various solvents." Bakelite resin is a phenol formaldehyde resin formed by condensation reaction of phenol or substituted phenol with formaldehyde.
