Plastic items that can and cannot be recycled.
Explanation:
Cannot be recycled: Telephone instruments, cooker handles, plastic covering on electrical wires, electric switches.
Thermosetting plastics are prepared from low molecular mass semi-fluid substances. Thermosetting plastic can withstand very high temperatures. During its curing process, the polymers link together to form a permanent chemical bond. So the items made from thermosetting plastics cannot be recycled.
Thermoplastics are substances that become plastic upon heating, then hardens upon cooling. The material can undergo this process repeatedly. Hence items made using thermoplastics can be recycled.
Can be recycled: Plastic toys, ballpoint pens, carry bags, plastic bottles, plastic chairs
