Vulcanisation accelerators

The vulcanisation accelerators of the LUBIO® NCL series are based on a newly developed cluster technology. The cross-linking of rubber products can both be accelerated and controlled with the help of this technology. The use of LUBIO® NCL allows for a reduction of the sulphur amount in the vulcanisation process which, among other things, contributes to the ageing resistance of rubber.
