Polyester: Meaning (information, definition, explanation, facts)

Polyester is a category of polymer whose monomer contains the ester functional group. Polyesters fibers are often used to make fabric.

Liquid crystalline polyesters are among the first industrially used liquid crystalline polymers. In general they have extremely good mechanical properties and are extremely heat resistant. For that reason, they can be used as an abradable seal in jet engines.
