WESTCO™ CTP N-cyclohexylthio-phthalimide CAS# 17796-82-6

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. Blooming may occur above 0.5 phr CTP. It is effective in marginal stock recovery.

Packaging: 25kg bags

Storage Conditions: Store closed containers in a cool, dry, well ventilated area. Store away from strong acids and avoid exposure to direct sunlight. Do not double stack. Shelf life using proper storage containers is one year from the date of manufacturer.
