There is a wide variation in plastic and FRPs formulations. Thousands of different chemicals are used in plastic production, including plastic monomers, epoxies, resins, colorants, surfactants, plasticizers and other additives. Many of the chemicals, minerals and heavy metals used in plastic production are considered to be human health hazards or environmental hazards.
There is also a great deal of variation in potential exposure levels to these substances depending on the process involved. For example, some chemicals may only be hazardous when vaporized during thermal process and be considered benign as plastic dust. The exposure risk for other plastics may vary depending on the size of the particulate created by the process and whether or not it is considered to be respirable. For these reasons, it is important for manufacturers producing or handling plastics and FRPs to gather Safety Data Sheets (SDSs) for the substances they are working with and conduct an evaluation to determine the exposure risks and relevant regulations specific to their processes.
