The chemical industry involves a wide range of various procedures, materials and plants. This high diversity requires independently custom-made sealing solutions. In delicate chemical processes, for example in reactors, generators and stirrers, it is significant that nothing harmful can escape from the plant. In processes involving fine and special chemicals, temperatures of up to +300 °C, it can push seals made of elastomers and plastics to their limits. The seals are additionally exposed to extreme temperature fluctuations during steam cracking. Likewise, the sealing materials must withstand especially aggressive, sometimes even toxic chemicals and high pressures. Seals must sure that chemical processes comply with the emission values. Because of these extreme operating conditions, robust and chemically resistant materials are essential to the chemical industry.
