Thomas Swan has developed a range of viscosity-reduction additives for the rubber processing and polymer industries, providing time, energy, cost and environmental benefits. Pepton® chemical peptisers catalyse the mastication of rubber, providing time, energy, cost and environmental benefits.
The dibenzamido diphenyl disulphide (DBD) chemistry used to produce the active ingredient within Pepton® is widely considered by the rubber processing industry to be more environmentally acceptable than traditional pentachloro thiophenol based peptisers. Thomas Swan’s DBD is the only fully REACH registered chemical peptiser.
A range of formulated Pepton® products is available, each having different concentrations of the active ingredient combined with a range of complementary proprietary additives that enhance peptising performance.
