Additives in plastics.

Abstract. The polymers used in plastics are generally harmless. However, they are rarely used in pure form. In almost all commercial plastics, they are "compounded" with monomeric ingredients to improve their processing and end-use performance. In order of total volume used, these monomeric additives may be classified as follows: reinforcing fibers,...

Plastics | Uses, Benefits, and Chemical Safety Facts

Plastics make possible many things people don’t recognize as plastic at all – like paints, protective coatings and linings, adhesives and glues, and sealants and insulation. Some plastics have additives that make them bacteria- or fire-resistant; or give them a rainbow of colors; or make them flexible; or fill them with bubbles to make them better insulators; or even add fibers to make high-tech composites.
