Abstract
CAPAC-DDTS, (CAS No. 53880-86-7), DDTS is slow acting accelerator suitable for natural rubber, SBR, isoprene rubber rubber, cis-polybutadiene etc. It is mainly used together with TMTD, TMTM as secondary accelerator to improve the processing safety of rubbers.
Identification
Name: Dimethyldiphenylthioperoxydicarbamic acid(CAS No. 53880-86-7 ),
CAS Registry Number: 53880-86-7
EINECS: 258-835-3
Application
CAPAC-DDTS is a secondary ultra accelerator for general purpose polymers (NR, SBR, IIR and EPDM). It can be used as primary accelerator in some continuous cure applications as well as in latex.
- Furthermore CAPAC-DDTS is used as an antioxidant in adhesive systems.
- It is mainly used together with TMTD, TMTM as secondary accelerator to improve the processing safety of rubbers.
- CAPAC-DDTS is regulated for use in articles in contact with food as specified under FDA 21 CFR 175.105, 178.2010, 175.300, 177.1210, 177.2600 and under BfR Recommendation XXI, Categories 1-4 and "Sonderkategorie".
Compounding Information
In NR latex, when used as a primary accelerator 1 phr of CAPAC-DDTS with 2.5 phr sulfur is a good starting point.
In EPDM CAPAC-DDTS has the highest solubility of all dithiocarbamates, offering the lowest blooming effect.
