Behaviours in Rubber:

Pepizol-7 considerably accelerates the peptizing of Natural Rubber and Synthetic Rubbers at mastication temperature above 80°C thus saving a lot of time and energy. The higher the temperature of rubber, the greater the efficiency.

However, the temperature of the rubber should not exceed 165°C, as otherwise, rubber will cyclize above this level. Masticating in the internal mixer is especially advantageous since the temperature required for peptizing are generally reached rapidly.

Effects of reinforcing Carbon Black on Peptization during compound mixing using Peptizol-7 have also been observed almost similar.

Functions & Advantages:

• Rapid and even dispersions as compared to conventional and known International Peptizers

• Reduces mixing cycles and thereby saves plenty of time and power

• Reduces viscosity of Rubber by Chemical Peptization with added chain lubrication

• Suitable for premastication as well as single stage processes

• Effective on open mi8ll above 80°C and in internal mixers upto 160°C

• Do not have any adverse effect on Scorch and Cure Characteristics of Rubber

• Do not affect physical properties and aging behaviour of the vulcanizates
