    The above mentioned factory was established in 1953, which is one of enterprises with the longest history of producing rubber chemicals in China. Relying upon 50 years' business & cultural base, the plant is always the pioneer of the industrial reform of rubber chemicals. The total assets of the plant total about RMB 100 million yuan and the annual production ability is 20, 000 tons. The plant is a professional enterprise of producing rubber chemicals, oil field chemical assistant and dye intermediate. The rubber antioxidant has been listed into the first place in China. So, this plant has set up long-term & steady relationship with many tyre plants and others large-scale tyre manufactures and the various large-scale oilfields upon the supply & demand of the rubber antioxidant. And the rubber antioxidant has been exported to many countries and regions such as Russia, Japan, Southeast Asia, etc. Therefore, the brand is gradually internationalized.

    The plant has passed the identification of ISO9001:2000 International Quality Management System. For several years, integrating science, industry and trade into one body, the powerful system has formed in the fields of scientific research, development, production, quality control and market service. Nowadays, the plany has developed the insoluble sulfur for rubber vulkacit with the type of IS-60 and IS-90 according to the requirement of development of tyre trade; the products has good market potential. The development of the insoluble sulfur for rubber vulkacit makes the plant step firmly to chemical industry and high science & technology.

    Fifty years have passed like an arrow; we must carry on the past and open a way for future. In the new century, our workers & staff will continue to follow the enterprise's spirit of "Honesty and Innovation, Pursue Excellence". The plant will regard the market as guide, rely on the science and technology, survive relying market as guide, rely on the science and technology, survive relying upon quality, and develop in culture. And the plant will firmly take the road of famous brand and internationalization and we must try our best to make the plant stronger and turn the plant into the largest production base of the chemical assistant in Central China and famous at home and abroad.
