Does CTP reduce natural rubber reversion?

SAFE will reduce natural rubber reversion on overcure. CTP has no effect on reversion. • One way to improve scorch and cure speed in a thiazole (MBT, MBTS) accelerated compound is to add a small amount of OBTS sulfenamide.

What is pentotard – PVI?

Pentotard – PVI offers linear and predictable response and is most sensitive to sulphenamide accelerated stocks and highly unsaturated rubbers. Pentotard – PVI can be used effectively in compounds based on NBR/PVC blends, polyacrylic rubbers and sulphur cured polyurethanes.

Is pentotard – PVI a scorch inhibitor?

Pentotard – PVI is an effective scorch inhibitor with almost all types of accelerators and in all types of sulphur cured diene rubber based compounds. Pentotard – PVI offers linear and predictable response and is most sensitive to sulphenamide accelerated stocks and highly unsaturated rubbers.

What is CTP reclaimation function?

CTP can also improve the storage stability of the rubber compounds and keep them from natural vulcanization during storage. Meanwhile, it has reclaimation function for rubber compounds that have been borne at high temperature or dangerous for scorching. Paper-plastic complex bag, 20KG/bag.

What is PVI used for?

PVI or CTP also known as N- (Cyclohexylthio)phthalimide used as ant scorching agent, is an flame retardant for NR and synthetic diene rubbers. PVI is a pre-vulcanization inhibitor which enables processing safety to be controlled in a predictable manner in sulphur curable compounds. What are the benefits and the features?

Is CTP a good thiazole retarder?

CTP is a very powerful retarder with sulfenamides. SAFE is good while PX and AK are modest retarders with a sulfenamide. BAX and SAX have little effect. Little advantage is gained by using CTP or SAFE with a thiazole. Cost effectiveness would go to the acid retarders.
