Product Overview

1,3-Diphenyl-2-thiourea, commonly called Thiocarbanilide, is a sulfur-containing compound used in rubber and chemical formulations. It is valued for its role in improving vulcanization performance and supporting stable processing behavior in elastomer systems.
Off-white powder. Easily soluble in ethanol and ether, completely insoluble in water and carbon disulfide. Soluble in dimethylformamide, acetone, chloroform, and benzene.
This product is an accelerator with a fast vulcanization speed. It is mainly used in natural rubber latex and neoprene dairy products. It can also be used in the manufacture of vulcanization capsules, water tires, tire repair rubber, wires and cables, industrial products, rubber shoes, etc.

Performance Benefits

Supports efficient vulcanization in rubber systems.
Improves processing stability.
Suitable for compounds requiring dependable performance.
Widely used in technical rubber formulations.

Typical Applications

Rubber compounding
Tires and technical rubber goods
Chemical intermediate uses
Specialty formulations requiring sulfur-containing additives
It can also be used as a heat stabilizer for emulsion polyvinyl chloride. It is especially suitable for soft products. The general dosage is 0.2-0.5%. It will not color plastic products, but it cannot prevent the products from being discolored by light. It cannot be used together with lead and cadmium stabilizers, otherwise it will cause discoloration of the product.

DPTUis also an intermediate for medicines and dyes, and is used in the production of indigo, methyl indigo, sulfur dyes, flotation agents, anti-acid agents, etc.
