What is a good peptizer for rubber?

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.

What is chemical peptizer used for?

Chemical peptizer designed for DBD based natural rubber such as NR. It is a blend of 40% dibenzamido diphenyl disulphide and organo metal complex on low melt carriers. Benefits: Chemical peptizer designed for DBD based natural rubber such as NR. It is a blend of 40% dibenzamido diphenyl disulphide and organo metal complex…

Why are rubber peptizers important?

Rubber peptizers play an essential role in this process by improving compound dispersion and facilitating mixing, thus contributing to performance and efficiency. What Are Rubber Peptizers? Effective Dispersion: Peptizers improve the dispersion of rubber particles, facilitating homogeneous mixing.

Does peptizer 66 disperse in rubber?

Peptizer 66 disperses readily in rubber and should be added at the beginning of the mixing cycle, using either internal mixers or open mills. Viscosity reduction is most effective when the rubber and peptizer are pre-masticated before adding the other ingredients.

What is peptizer 66?

Peptizer 66 is also available as Akroform® PEP 66-80/EPR/P. This polymeric masterbatch contains 80% Peptizer 66 and has a specific gravity of 1.49. Polymer bound or encapsulated dispersions are a proven means of upgrading plant safety, efficiency, quality & raw material control.
