Cross-Linkers
The LUBIO® Sulfosafe cross-linkers contribute to develop a three-dimensional network during vulcanisation. The degree of cross-linking has an influence on the properties of the rubber (e. g. on the hardness, the viscosity and the melting point). With the use of LUBIO® Sulfosafe preferably disulfidic bonds are created which prevent a reversion of the vulcanised rubber.
