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.
