What is the preparation properties and uses of Bakelite?
Very smooth molding can be obtained from this polymer. Bakelite moldings are heat-resistant and scratch-resistant. They are also resistant to several destructive solvents. Owing to its low electrical conductivity, bakelite is resistant to electric current.
How is Bakelite prepared with reaction?
Bakelite is formed from the reaction of phenol and formaldehyde. Basically it is formed in two steps. In the first step formaldehyde reacts with phenol and produces o-Hydroxymethyl phenol. Then o-Hydroxy methyl phenol and phenol come together and form Bakelite.
What are the raw materials used to make Bakelite?
Answer: Raw material that is used to make bakelite is equal parts of phenol ( carbolic acid) and formaldehyde.
What are two uses of Bakelite?
USES OF BAKELITE:
- Bakelite due to its high resistance to electricity and heat is used in automotive components and industrial applications.
- Due to its excellent insulating properties it is used for making switches and other electrical appliances.
- It is also used to make various kitchenware products like frying pans etc.
What is Bakelite in organic chemistry?
A hard, infusible, and chemically resistant plastic, Bakelite was based on a chemical combination of phenol and formaldehyde (phenol-formaldehyde resin), two compounds that were derived from coal tar and wood alcohol (methanol), respectively, at that time.
What are the properties of Bakelite?
Properties of Bakelite
- 1.It can be formed quickly.
- Very smooth molding can be obtained from this polymer.
- Bakelite moldings are heat resistant and resistant to scratches.
- And they are resistant to many destructive liquid chemicals.
- Due to the low energy efficiency, bakelite is resistant to electricity.
What is the major use of Bakelite?
Bakelite is a thermosetting plastic (phenol-formaldehyde resign). It is used for making TV cabinets, telephone components, billiard ball, bearings, electrical goods etc. It is prepared by the polymerisation reaction between formaldehyde and phenol.
What are the ingredients of Bakelite?
What is Bakelite made from?
How do you identify Bakelite?
Using Formula 409 Cleaner To use, dampen a cotton swab with 409 and rub it gently on the inside of the item being tested. If it is Bakelite, the swab will turn yellow. If a piece is lacquered, it may test negative with 409. Black Bakelite pieces often fail this test as well.
Which type of plastic is Bakelite?
thermosetting polymer
Bakelite is one example of a thermosetting polymer. A thermosetting plastic is a polymer that irreversibly becomes rigid when heated. Such a material is also known as a thermoset or thermosetting polymer.
