Vulcanisation

Vulcanisation is a crucial process in the production of hard rubber. In this process, rubber is treated with sulphur under specific conditions to improve its properties. During the vulcanisation process, the rubber molecules react with the sulphur, which leads to the formation of long molecular chains.

This chain structure gives the rubber greater strength and resistance to ageing. The cross-linking of the molecules makes the rubber more resistant and more elastic, which makes it suitable for a wide range of applications in various industries.

The exact sequence of the vulcanisation and the parameters that must be controlled during it are decisive for the quality and the final properties of the hard rubber.
