If media such as hydrochloric acid (HCl), sulphuric acid (H 2 SO 4), chromic acid (H 2 CrO 4) and hydrofluoric acid (HF) are used, the issue of operational safety is a top priority. If damage were to occur, for example with aggressive hydrochloric acid (HCl), it would be astrophic. Chemical resistant plastics play an important role in the planning and development of facilities and machinery ...
