Primary emphasis is placed on their suitability for use and their safety. That explains our success around the world. At the same time, it is important that we maintain consistently high quality and never stop the development process. A guarantee that we can stand behind. And one that we want to keep.


Natural rubber is masticated to improve processing. By breaking down the molecular chain the polymer viscosity is reduced. This is usually achieved by mechanical forces in a mixer, which consumes energy.


Aging processes, which are caused by oxygen or heat, change the properties of the vulcanizates. Rubbers generally are subject to such changes that occur in the course of time and can lead to partial or complete destruction. Possible consequences are depolymerization, fatigue, brittleness, cracks and even disintegration. The resistance of a rubber article to oxygen, ozone and other reactive substances is determined mainly by the elastomer on which the compound is based and by the chemicals that are added to retard the destructive processes.



Vulcanization is the conversion of a high-molecular material from the plastic to the elastic state. One of the key chemical reactions in this process is that of rubber with sulfur. Sulfur vulcanization, widely used in the rubber industry, requires the use of vulcanization accelerators such as Vulkacit.
