German Food Legislation (BfR recommendation XXI) : not approved

Supply Form : 25 kg in cardboard boxes with PE-inliner

Storage Stability
In originally sealed package In dry places at max. 25 ^oC : min. 1 year

Classification and Labelling
Deovulc
BG 200 is labelled as "harmfull" (Xn)according to EEC directives. For more detailed
information, please refer to our Material Safety Data Sheet.

Application
For 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 acceleratiors

Composition : Synergistic combination of highly active accelerators containing DCBS.

Apperance : Beige powder

Analytical Values:

• Total sulphur(%) ASTM D 1552 (LECO) :16.5-19.5
• Density at 20^oC(g/cm³) DIN ISO 787 part 10A : 1.2
  

Dosage (phr) : 3-5

German Food Legislation (BfR recommendation XXI) : not approved

Supply Form : 20 kg in cardboard boxes with PE-inliner

Storage Stability
In originally sealed package In dry places at max. 25 ^oC : min. 1 year

Classification and Labelling
Deovulc
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).

Application
Deovulc 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 E

Description : Sulphur donor

Active Substance : Dithiodicaprolactam 80% in EPDM

Apperance : Off-white to grey granules.

Analytical Values:

• Total sulphur(%) ASTM D 1552 (LECO) :1.5-19
• Density at 20^oC(g/cm³) DIN ISO 787 part 10A : 1.1
  

Dosage (phr) :

• Conventional systems : 06.10
• SEV-systems : 0.5-1.5
• EV-systems : 0.5-2.0
  

German Food Legislation (BfR recommendation XXI) : Approved

Supply Form : 20 kg in cardboard boxes with inliner PE-bag

Storage Stability
In originally sealed package In cool and dry places : min. 1 year

Classification and Labelling
Deovulc 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.

Application
For
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.
