ctp is a rubber prevulcanization inhibitor/cure retarder
WESTCO™ CTP is a rubber prevulcanization inhibitor/cure
WESTCO ™ CTP is a pre-vulcanization inhibitor/cure retarder for both natural and synthetic rubber. It provides predictable scorch control in most sulfur vulcanized rubber compounds, allowing single-stage mixing at higher processing temperatures and higher curing temperatures. Is activity is linear and higher than most retarders.

Prevulcanization Inhibitors - CROW
Prevulcanization Inhibitors for Sulfur Vulcanization To avoid premature vulcanization during processing, retarders are often added to the cure system. These compounds increase the induction time by reacting with the active accelerator fragment which slows down or temporarily prevents zinc salt formation.

retarders for rubber cures
Retarders in the rubber industry are in an unusual position — some rubber technologists insist that retarders aren’t needed and are the sign of a poorly thought-out cure system. Yet copious amounts of retarders are consumed in the rubber business every year. While there is

Product Data Antiscorching Agent PVI(CTP)
PVI is normally used at levels from 0.1 to 0.4 phr. Higher levels may give a slightly reduced cured modulus. If necessary the modulus loss may be adjusted with additional sulfur and up to 40 % of the amount of PVI is recommended. The reaction of PVI with sulfur and accelerator generates phthalimide as a byproduct.
