Predispersed Rubber Chemical CTP-80
Identification:
Chemical Name: Cyclohexylthiophthalimide
Synonym: Pre-Dispersed Polymer Bound Chemical CTP-80；Anti-Scorcher CTP (PVI)
CAS: 17796-82-6
EINECS: 241-774-1
Molecular Formula: C14H15O2SN
Properties:Active ingredient CTP is a vulcanization retarder of nature rubber and diene rubbers, which can unnoticeably prolong total vulcanizing time. It can improve processing safety and not affect properties of vulcanizates with sulfenamides or thiazoles. This product can significantly improve the storage stability of unvulcanized rubber and high temperature processing safety performance, fully improve the production capacity of the equipments. It does not lead to contact stain. Non-staining, little colored for white rubber compounds.
Dosage: Usually 0.2-2.0phr, will be blooming if more than 5.0phr.
