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