Sulphur Donors
Deovulc M splits off sulphur at high temperatures only. Therefore steep vulcanization curves can be obtained. Monosulphidic bridges are formed resulting in a good heat-resistance and low compression set of the vulcanizates. Deovulc M can be used in all standard polymers as a replacement for sulphur in heat-resistant compounds. In conventional systems, 1.0 to 1.5 phr sulphur can be replaced by 0.6 to 1.0 phr Deovulc M. In many cases ratios of 1:1 Deovulc M / Sulphenamide or 1:1.5 Deovulc M /MBTS have proven to be most effective. In SEV systems equal amounts of sulphur can be replaced by Deovulc M. In EV systems double amounts of Deovulc M are recommended.
Deovulc CLD-80E is used for nitrosamine-free, reversion-stable compounds and products of excellent heat-ageing properties made from NR, SBR, NBR or EPDM. Deovulc CLD acts as nitrosamine-free sulphur donor, which generates monosulphidic cross-linking during the vulcanization. Deovulc CLD is typically used in combination with accelerators and low sulphur dosages. The vulcanizates show a good heat-resistance and low compression set.
Deovulc M and Deovulc CLD are classified as hazardous
materials according to EEC directives. For more detailed information please refer to our MSDS.
