3.Application: It has been used as the vulcanizing agents for butyl rubber, natural rubber, styrene-butadiene rubber, especially for butyl rubber, as well as analytical agent, etc. It has been used as a vulcanizing agent for butyl rubber, natural rubber, styrene-butadiene rubber, and polysulfide "ST" type vulcanized rubber, it is especially suitable for butyl rubber. Oxidants have an active effect on it. It is easy to disperse in the rubber compound, vulcanizes quickly, and the tensile strength of the vulcanized rubber is high. The critical temperature is relatively low, and it tends to burn. Adding some anti-scorch agents, thiurams, thiazoles, and dithiocyanoformate accelerators can effectively improve the safety factor of using.

Use: 1)Accelerator & vulcanizer for rubber;


3)Used as a non-sulfur vulcanization accelerator by direct reacting with peroxy-free radical to tie up free radicals and metal adhesion promoter between metal and rubber;

4)Used as a vulcanizing agent for EPDM (ethylene-propylene diene rubber) to improve heat resistance;

5)Used as a curing agent for coating system and electrical encapsulation.

4. Safety instructions: Toxic. Operation must be installed with rubber gloves, a respirator and eye protection by wearing protective clothing to avoid contacting with skin and inhalation. Stay away with fire and heat source of high temperature.

5. Packing: Kraft paper bag lined with plastic bag, net weight 20 kg per bag

6. Storage: Stored in a cool, ventilated place. The shelf life is 12 months after manufacturer date. It is still available if retest result is qualified after expire date

7. Transportation: Avoid water, exposure and violent collision .Do not transport with strong oxidizers.
