Polymer

True or False? All polymers are plastics.

• True

• False

Which type of plastic can be repaired by welding?

• Thermoset plastics

• Thermoplastics

Answer explanation

Welding involves heat, and only thermoplastics can be deformed using heat. With thermoset plastics you need to use other methods like adhesives.
