The special properties of plastic make it an ideal material for many products. As a safe material, odourless, tasteless, inert to chemicals, non-toxic and resistant to solvents, it is the perfect material for medical utensils. Toys made of plastic are invariably safer for children than those of other materials, and the light but strong nature of plastic makes it suitable for industrial applications such as safety helmets, chemical drums and insulating material. When objects of personal and daily use such as combs, toothbrushes, and umbrellas are added to this list, it is clear that plastic has become indispensable to everyday life as we know it.
