The vulcanisation of high tech synthetic rubber sealing profiles with complex profile geometries and an extremely wide range of contents and coatings is a science in itself. Today's modern technologies make it possible to combine dimensionally accurate manufacturing and high system throughput with environmental protection. Gerlach is the first manufacturer worldwide to develop systems that do not harm the environment, meaning that the environment is kept almost 100% protected from pollutants and odour pollution. This integral ecological concept is certified by means of ongoing tests carried out together with well known testing bodies.
