Additives :

Most plastics contain other organic or inorganic compounds mixed in. The amount of additives ranges from zero percentage for polymers used to wrap foods to more than 50% for certain electronic applications. for example additives such as Fillers improve performance and decrease producing costs. Stabilizing additives include fire retardants to lower the flammability of the product. Many plastics contain fillers, relatively inert and inexpensive materials that make the product cheaper. Typically fillers are mineral in origin same as chalk. Colorants are common additives, although their weight impact is small. Many of the controversies associated with plastics are associated with the additives.

Most of the activity in life is influenced by plastics and many depend completely on plastics products. Additives widely use in cars tools for example etic bumper, dashboards, steering wheels and switches; medicine without plastic hypodermic syringes and artificial hip joints. Telecommunications, dependent on plastic telephones, circuit boards and cable insulation. Our entertainment and leisure depend on the unique combination of characteristics offered by plastics in sports equipment and clothing, CDs, video and audio tape, television and cinema indeed you wouldn't be able to read this over the internet without plastics!

Without additives, plastics would not work, but with them they can be made safer, cleaner, tougher and more colorful. Additives cost money, of course, but by decreasing production costs and making products last longer, they help us to save money and conserve the world's precious raw material reserves. In fact, our world today would be a lot less safe, a lot more expensive and a great deal duller without the additives that turn basic polymers in to useful plastics.
