What is Cyclohexylthiophthalimide?

Description

Cyclohexylthiophthalimide, also known as scorch retarder, early vulcanization inhibitor, scorch retarder CTP, and scorch retarder PVI, is white, light yellow or light yellow-brown crystal at room temperature. The product recrystallized from n-heptane is white crystals. Soluble in acetone, benzene, toluene, ether, ethyl acetate and ethyl acetate, slightly soluble in gasoline, insoluble in kerosene and water, soluble in hot carbon tetrachloride, ethanol and heptane.

Description

Cyelohexyl thiophtalimide is a rubber chemical widely used as a vulcanization retarder. Sensitization sources are perhaps protective gloves.

The Uses of Cyclohexylthiophthalimide

N-(Cyclohexylthio)phthalimide is a vulcanization retarder widely used in various rubber products.

The Uses of Cyclohexylthiophthalimide

N-(Cyclohexylthio)phthalimide is used in preparation of high ortho-position Phenolic adhesive resin for improving steam aging-resistance of rubber.

What are the applications of Application

Cyclohexylthiophthalimide is a very effective scorch retarder for all sulfur vulcanized dienes and low unsaturation rubbers, such as natural rubber, styrene-butadiene rubber, nitrile rubber, butyl rubber, neoprene, isoprene Rubber, butadiene rubber, EPDM rubber, etc. all have good anti-scorch effect, and their activity is not affected when used in combination with other rubber additives.
