  • Acrylonitrile butadiene styrene (ABS): It is strong enough to deal with force. And it can do it without breaking. Electronics, vehicle parts, and LEGO pieces are some of the products that include ABS.
  • Polyvinyl Chloride (PVC): This strong product comes in soft and hard. It exists in pipes, surfaces, glazing, and wires, among other things.
  • Polycarbonate (PC): This visible, strong plastic is used in safety eyewear. And it is used in parts of cars.
  • Nylon, or polyamide: It is a sturdy material utilized in clothes, shafts, and gears. 
  • PET, or polyethylene terephthalate: It is simple, strong stuff. Meal boxes, drinks, and fabrics all carry it.

There are variants of these materials. Also, they are helpful for an array of everyday tasks.
