Difference Between Thermoplastic and Thermosetting Plastic
Thermoplastic Thermosetting Plastic
Thermoplastics have low melting points and low tensile strength. Thermosetting plastics have high melting points and tensile strength.
Answer:
Difference Between Thermoplastic and Thermosetting Plastic
Thermoplastic can be synthesized by the process called addition polymerization. Thermosetting plastics are synthesized by condensation polymerization.
Thermoplastic is processed by injection moulding, extrusion process, blow moulding, thermoforming process, and rotational moulding. Thermosetting Plastic is processed by compression moulding, reaction injection moulding.
Thermoplastics have secondary bonds between molecular chains. Thermosetting plastics have primary bonds between molecular chains and held together by strong cross-links.
Thermoplastics have low melting points and low tensile strength. Thermosetting plastics have high melting points and tensile strength.
Thermoplastic is lower in molecular weight, compared to thermosetting plastic. Thermosetting Plastic is high in molecular weight.
These are some of the differences between thermoplastic and thermosetting plastic.
Some examples of thermoplastics are listed below.
Polystyrene
Teflon
Acrylic
Nylon
Examples of thermosetting polymers include:
Vulcanized rubber
Bakelite
Polyurethane
Epoxy resin
Vinyl ester resin
