Differentiate between thermoplastic and thermosetting plastic. Give Four examples of each. ❌❌NO SPAM❌❌
Answers
thermoplastic can be again be moulded into desire shape but thermosetting plastic cannot be moulded beacuse it doesnot get soft on heating.
Example of thermoplastic:it is used for making buckets,pens.
Example of thermosetting plastic:it is used for making pvc pipes , handles of cooking utinsils,etc.
Step-by-step explanation:
Thermoplastic 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.
