Used in bearings, gears, mouldings, wall plugs, etc. Used for pipes, tanks, boat hulls, etc. Free learning from The Open University. Orange Box Ceo 5, views. A thermosetting polymer is a prepolymer in a soft solid or viscous state that changes irreversibly into a hardened thermoset by curing. Cancel Unsubscribe.
Though thermoset plastics and thermoplastics sound similar, they have very different Thermoset plastics contain polymers that cross-link together during the. The terms thermoplastic and thermoset describe the processability of a material as the temperature is changed. A polymer that becomes plastic and flows on heating, either by reason of crystal melting or by exceeding the glass transition temperature Tg is thermoplastic. Thermoplastics and thermosetting plastics are two separate classes of polymers, which are differentiated based on their behavior in the.

Thermoplastics and thermosets. As already stated, polymers including rigid plastics were first developed in the last century from natural precursors. For polymers, one useful classification is whether they are thermoplastic or thermosetting polymers. As you read in the last reading assignment, thermoplastics.
