Nylon is a thermoplastic that is self-lubricating and resists abrasion. Thermoplastics are plastics that do not undergo a chemical change in their composition when heated, and hence, they can mould several times. The primary challenge in distinguishing an elastomer vs polymer is that elastomers are a subset of polymers. Die Form der Klappdeckelgestelle eignet sich für manuelle Mehrkanalpipetten und. Thermosets are crosslinked polymers. The key difference between thermoplastic and thermosetting plastics involves the fact that thermoplastics can melt under heat after curing, while thermoset plastics keep their form and remain solid under heat once cured.
