Product Description: Peptizer 66 is an activated 2,2’-dibenzamido diphenyldisulfide (DBDD) absorbed on a clay carrier. It can be used as processing aids/viscosity reducers for natural and synthetic rubbers. Applications: Peptizer 66 is an effective chemical peptizers primarily used for natural rubber. Recommended dosage levels in natural rubber range from 0.05 to 0.5 phr (as final mixing temperature increases, the lower levels should be used). Synthetic rubbers require approximately 2.0 phr. More specific dosage recommendations are included on page 2 of this data sheet. Benefits of using Peptizer 66: - lower viscosity/improved processing
- lower dump temperatures with subsequent mixing
- improved mold flow
- improved uniformity of extrusions and calendared sheets
- little effect on vulcanizate properties vs. mechanically masticated rubber
- acceptable under FDA regulation 21 CFR 177.2600
