Physical Properties of Polymers

Physical Properties of Polymers Polymer: A chemical compound or mixture of compounds formed by polymerization and consisting essentially of repeating structural units is called ‘Polymer’. Polymers range from familiar synthetic plastic such as polystyrene to natural bio-polymers such as DNA and proteins that are fundamental to biological structure and function. Physical Properties: Physical properties of polymers […]

Physical Properties of Polymers

Melt Spinning , Dry spinning and Wet Spinning Method

Man-made fibers are manufactured by spinning the polymer. There are three major types of spinning process. They are- █ Melt Spinning (It is used for polymers that can be melted easily.) █ Dry Spinning (It involves dissolving the polymer into a solution that can be evaporated.) █ Wet Spinning (It is used when the solvent can’t be evaporated and must be removed by chemical means.)
