ctp is 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.
