1. decrement when heating: ≤ 2.0%
2. insoluble matter in benzene: 77~83%

　　1. The product is widely used for various kinds of rubber, natural rubber, sulfur and vulcanized synthetic sizing material, playing a quick vulcanizing role. It possesses a broad vulcanizing flat area, with fine physical and mechanical and anti-aging performances of vulcanized sizing material.
　　 2. The critical temperature of the product's vulcanization is low (125°C), so it can be used as a retarding agent of vulcanization and anti-burning agent in the system of neoprene and sulfur-free vulcanization.
　　 3. The product is applicable for thiuram and dithiocarbamic acid as a butyl rubber accelerator.
　　 4. It can be used in the sizing material of light color and water-stable chlorosulfonated polyethylene together with tribase butenedioic acid lead.
　　 5. Besides, it is suitable for plasticate of green rubber as a kind of chemical plasticizing agent, not affecting vulcanizing result.
　　 6. Due to its features of easy dispersing and no blooming in sizing material, the product is widely used in tire, inner tube, tape and rubber shoes and other rubber products.
　　 7. It is a kind of particle product, so it is easy to be correctly measured and as a dust-free product, it can be used to better production conditions according to the requirements for materials' safety and environmental protection.

　　1~2 phr used as first accelerating agent and 0.2~0.5 as second accelerating agent, please see the following form (for reference):
　　The product can be added in as an accelerating agent in final melting.
It can be added in composition together with sizing material as a plasticizing agent.

The product can be stored in a shady, cool and dry place for one year.
