What is a thermoset plastic example?
Common examples of thermoset plastics and polymers include epoxy, silicone, polyurethane and phenolic. Different thermosets provide different advantages when used as a production material. For example, epoxies are highly elastic, tough and resistant to many chemicals while phenolic is highly flame resistant.
What is Bakelite and its uses?
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.
Is Bakelite dangerous?
If a Bakelite product breaks, the synthetic materials become airborne, and may result in inhalation, ingestion or direct skin contact. Bakelite collectibles are beautiful but deadly. Just like any other plastic-based product, disposing Bakelite is extremely hazardous to the environment.
What property makes Bakelite so hard?
Statement 1: Bakelite is hard and has high melting point. Statement 2: Intermolecular forces of attraction in it are H-bonding.
Is Bakelite still used?
Bakelite still has some of its classic applications in automotive and electrical products. But the material also is used in space shuttles, Harp said. Sumitomo Bakelite Co. Ltd., a phenolics maker in Japan that dates to an early license, no longer uses the formal Bakelite trade name on its materials, a spokesman said.
What is Bakelite formula?
(C6-H6-O.C-H2-O)x
Why does Bakelite not melt when heated?
So, then, if the whole enchilada is a giant molecule, no amount of force will “separate” it from other molecules, unlike the ice-scenario or the iron-scenario above. So, Bakelite cannot “melt”. All it does when you heat bakelite is that it starts to decompose, and pieces of the giant molecule start to fly off and burn.
How hot can Bakelite get?
The material.
