BG 200 is labelled as "harmfull" (Xn)according to EEC directives. For more detailed
information please refer to our Material Safety Data Sheet.ApplicationFor nitrosamine-free vulcanized articles (mainly EPDM) which have to be non-blooming and non-staining*. Slightly improved acceleration-speed compared with Deovulc BG 187.Notes:Deovulc BG200 contains long-chain zinc-dithiophosphates which gives reduced smell during vulcanization compared with Deovulc BG 187.Name : Deovulc BG 162 Description : Blend of acceleratiorsComposition : Synergistic combination of highly active accelerators containing DCBS.Apperance : Beige powderAnalytical Values:Total sulphur(%) ASTM D 1552 (LECO) :16.5-19.5Density at 20oC(g/cm3) DIN ISO 787 part 10A : 1.2Dosage (phr) : 3-5German Food Legislation (BfR recommendation XXI) : not approvedSupply Form : 20 kg in cardboard boxes with PE-inlinerStorage Stability In originally sealed package In dry places at max. 25 oC : min. 1 yearClassification and LabellingDeovulc
BG 162 is classified as hazardous according to EEC directives. For more detailed
information please refer to our Material Safety Data Sheet.Befavour and Effects:Deovulc BG 162 is designed as an 'efficient vulcanizing system (EV)'. It is used in combination with a reduced amount of suplhur (0.4-0.7 phr).ApplicationDeovulc BG 162 is a blend of accelerators especially for heat-resistant moulded NBR-articles which meet high requirements on physical properties. Processing of Deovulc Bg 162 does not develop dangerous nitrosamines. Deovulc BG 162 can be used in combination with other sulfenamides or on its own as single accelerator.Name : Deovulc CLD-80 EDescription : Sulphur donorActive Substance : Dithiodicaprolactam 80% in EPDMApperance : Off-white to grey granules.Analytical Values:Total sulphur(%) ASTM D 1552 (LECO) :1.5-19Density at 20oC(g/cm3) DIN ISO 787 part 10A : 1.1Dosage (phr) :Conventional systems : 06.10SEV-systems : 0.5-1.5EV-systems : 0.5-2.0German Food Legislation (BfR recommendation XXI) : ApprovedSupply Form : 20 kg in cardboard boxes with inliner PE-bagStorage Stability In originally sealed package In cool and dry places : min. 1 yearClassification and LabellingDeovulc CLD-80 is classified as hazardous material according to EEC directives and labeled as irritant (Xi). For more detailed
information please refer to our Material Safety Data Sheet.ApplicationFor
nitrosamine-free reversion-stable compounds and products of excellent heat ageing made from NR SBR NBR or EPDM. Deovulc  CLD-80 E acts as nitrosamine-free suplhur donor which generates monosulfidic cross-linking during the vulcanization. Deovulc CLD-80 E is typically used in combination with accelerators and low sulphur dosages. The culcanizates have good heat resistance and low compression set.More Details.
