TRANSCRIPT
Your partner for all aspects of rubber technologyThe performance of elastomeric materials and components with regard to resistance, elasticity, lifetime and functional reliability depends on many factors. Most significant are the quality of the raw materials used, the constituents and the processing method in all its individual stages such as mixing, extruding, shaping and vulcanization.In this and many other branches of rubber technology, DIK offers an extensive range of services.
Experienced chemists, physicists and engineers work at DIK in well equipped labs, dealing with orders from all over the world. Modern project management ensures smooth work sequences and high quality results. The accuracy and reliability of the testing is guaranteed by application of a broad spectrum of test procedures accredited. DIK uses state of the art equipment to carry out contracted work and for interdisciplinary problem solving.
