Bakelite's unique properties lent itself to extrusion casting. ~ Properties of Bakelite Bakelite is a non-conductive and heat resistant material makes it ideal for electrical insulators. It came in several colors, including translucent and marbled shades by the 1950s. Write any two uses of Bakelite. 4) preformed. NB Your answers may be given in either order. Clever collectors have named yellow transparent Bakelite "apple juice." Phenolic resins (Phenoplasts) are synthetic thermosetting resins invented by Dr. Leo Baekeland in 1907. Classification of Bakelite Sheets is based on the type of material used along with bonding agent to improve the properties of Bakelite laminated Sheets. PHENOLIC BAKELITE PAPER SHEET HP2061 ... HP 2061 has excellent strength, weatherability and elec-trical resistance properties. Properties and Synthesis. Yes, Bakelite jewelry can be transparent in color, too. Moreover, it could be molded very quickly, an enormous advantage in mass production processes where many identical units were produced one after the other. These colors vary, like with the solid color pieces shown above, but are most often found in yellow, green, and red. Typical applications include insulation of electrical and mechanical parts and structu-ral components. Bakelite made perhaps its largest stamp on the world of fashion. Bakelite was very rarely molded into individual pieces of finished jewelry. There are several variables in the method of polymerization, depending on the properties desired. Bakelite can be molded, and in this regard was better than celluloid and also less expensive to make. 2)It was also used in other diverse products such as jewellery, kitchenware, and toys. There are two type of materials used along with synthetic resin (bonding agent) to enhance the properties of Bakelite sheets (Phenolic Laminates) i.e. 2 See answers 17122006 17122006 Uses of Bakelite 1)It was used for its non-conductive and heat-resistant properties in electrical insulators, and also in radios and telephones. Sometimes you will find a piece of red transparent Bakelite nicknamed "cherry juice" as well. Properties and Uses of Bakelite. The great majority of Bakelite jewelry was made by hand from stock shapes of raw material. Moulding powders based on melamine–phenol–formaldehyde resins were introduced by Bakelite Ltd, in the early 1960s. Bakelite resin is a phenol formaldehyde resin formed by condensation reaction of phenol or substituted phenol with formaldehyde. Choose TWO letters A-E. Write your answers in boxes 9-10 on your answer sheet. A the function which the object would serve. Key Difference – Bakelite vs Plastic Plastic and Bakelite are both organic polymers, having a very large molecular weight though there exists a difference between the two based on their properties and usage. Bakelite is the first synthetic plastic and is known as a “material of thousand uses” due to its versatile applications. B the ease with which the resin could fill the mould Some of the principal physical properties of mouldings from these materials are given in Table 24.1. Which TWO of the following factors influencing the design of Bakelite objects are mentioned in the text? The material is often called Bakelite. Bakelite is a condensation polymer that requires two monomers - phenol and formaldehyde. Bakelite jewelry became immensely popular in the 1920s as an affordable and attractive replacement for other materials. ~ Uses of Bakelite It was used for its non-conductive and heat-resistant properties in electrical insulators, and also in radios and telephones.
