Chemical media are used in numerous machines, plants and processes. For a high operational safety and reliability, engineers must plan and design their facilities so that the components can withstand contact with aggressive chemicals. If media such as hydrochloric acid (HCl), sulphuric acid (H2SO4), chromic acid (H2CrO4) 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 catastrophic.
Chemical resistant plastics play an important role in the planning and development of facilities and machinery. However, not all plastics are suitable for contact with every chemical medium. Information about the chemical resistance of plastics can often be found in summary charts. However, the results usually only take individual criteria into account. A combination of different influencing factors can usually only be investigated in practice, for each individual application.
To select the appropriate chemical-resistant material, designers must always consider the specific influencing factors in their application.
Our chemical-resistant thermoplastics and composites have been used by engineers, developers and facility operators for decades, wherever chemical media are stored or used in processes.
The significant influencing factors include the continuous operating temperature, mechanical loads, weather influences, fire performance requirements and electrical conductivity. For example, if a material has a high resistance to a certain medium, but is not suitable for the anticipated continuous operating temperature in the application, a different material must be chosen.
