Question

Give the characteristics properties and important uses of polythene and
bakelite​

Answer 1

Answer:

characteristics of Teflon are as follows: 1.It maintains high strength, toughness and self-lubrication at low temperatures. 2. Its melting point is 600 K, 327 °C.

...

Characteristics of polythene are as follows:

have low strength.

Its density: 0.88–0.96 g/cm cube.

Polythene is of two types:high density and low density.

Bakelite has a number of important properties. It can be molded very quickly, allowing identical units to be mass-produced. Moldings are smooth, retain their shape and are resistant to heat, scratches, and destructive solvents. It is also resistant to electricity, and prized for its low conductivity.
