Styrene and Styrofoam 101 - Safer Chemicals, Healthy Families

May 26, 2014 · Styrene isn't only found in styrofoam products. Plastic, rubber, carpets, and even packing peanuts all have traces of styrene. So our chances of exposure come from a variety of sources. According to OSHA, approximately 90,000 workers creating boats, tubs, and showers are potentially exposed to styrene in the manufacturing process.
