Plastic

Plastic was a type of polymer used in the construction of objects.

The ancient art of making a splint, according to Katherine Pulaski, included components such as two flat pieces of plastic, or wood, and a bandage. 

While growing up on 22nd century Earth, young Jonathan Archer used to chase Danica Erickson around the backyard with a plastic laser pistol. 

The skin of androids discovered on the planet Mudd during the mid-23rd century was covered with a self-renewing plastic over a skeleton of beryllium-titanium alloy. 

In 2365, Doctor Katherine Pulaski suggested a splint could be made of two flat pieces of wood or plastic with a bandage to secure them to a fractured limb to immobilize it.
