A material composed of large molecules formed by linking a series of smaller chemical building blocks into long chains. Individual building blocks, called monomers, can be as simple as a few atoms or as complicated as ring-shaped structures containing a dozen or more atoms.
Examples of synthetic polymers include:
- Nylon, Polyester, and Rayon
Polymers are now commonly used to make poppets and valve plates for reciprocating compressor valves and labyrinth interstage seals for centrifugal compressors.
