Question

Classify into thermosetting plastic and thermoplastics on the basis of their characteristics.
(1) The plastics that are poor conductors of heat and electricity.
(2) Plastics which when moulded once, cannot be softened by heating.
(3) The plastic which gets deformed easily on heating and can be bent easily.​

Answer 1

1). Thermosetting plastic

2). Thermosetting plastic

3). Thermoplastic

Explanation:

• Thermosetting plastic is characterized as plastic that becomes hard and rigid on heating and therefore, it can not be reversed back.
• While thermoplastic is the plastic that weakens on heating and it can be remolded back into any shape. Thus, it can be recycled.
• Thus, thermosetting plastics can tolerate heat and are used in ovens etc. because they get strengthened by heat while vice versa happens in the case of thermoplastic as they melt on receiving heat and get hard on cooling.
• On the basis of such details, the given are characterized as thermosetting and thermoplastic.
