About us

Sichuan Zhongxinhuacheng Petrochemical Co., Ltd. was established at Puguang microfibre new material industrial park, Xuanhan county, Dazhou city, Sichuan province in October 2016, with a registered capital of 107.7 million yuan, unified social credit code of 91511722MA62E8PB7W, an area of 300 acres. It was a professional manufacturer of rubber additives "insoluble sulfur" and ancillary products, with an annual output 60,000 tons of high quality insoluble sulfur. The company is a key project in Sichuan province and a key enterprise in Dazhou city. The industrial park where the company is located has abundant sulfur and natural gas resources, with an annual output of 2 million tons of high-quality sulfur. It has a professional technical team and engaged in the technical research of insoluble sulfur products   since the early 1990s, from the water production technology in 1991 to the most advanced high temperature liquid sulfur atomization production technology (independent invention patent No:ZL201110039618.5). In 2013, it was appraised as "internationally advanced" by the national level. This technology has the advantages of low cost, continuous production and no three waste discharge, and has reached the international advanced level. This production process was listed in the Petrochemical Green Process List (2019 Edition) by the Petrochemical Federation in 2019.

Sichuan Zhongxinhuacheng Petrochemical Co., Ltd. is high technology of leading manufactures for rubber vulcanizing agent in the world. Focus on producing the best insoluble sulfur in the world.

Product description

Product description: Insoluble sulfur is a non-toxic, flammable yellow powder with the properties of insoluble carbon disulfide. It is produced by ordinary sulfur through hot polymerization, molecular chain of sulfur atoms more than 108, there is high polymer viscoelastic molecular weight distribution, so also known as elastic sulfur or polymeric sulfur, belongs to inorganic polymer chemical raw materials. Company's products are oil-filled high dispersibility and heat resistance (IS content under the condition of 120°c/15min to stay above 50%, under the condition of 105°c/15min to stay above 85%). High insoluble sulfur content and soluble sulfur content less than 3%, its good dispersion performance is superior to the similar foreign products, of which shelf life is more than and high temperature stability. At 80°c, the weekly content decreases less than 1%, and other properties remain unchanged. Can satisfy with high temperature shipping in summer, superior to any similar products on international market.

Application: insoluble sulfur is mainly used as an advanced vulcanizing agent in rubber industry. It is suitable for natural rubber and synthetic rubber. Rubber hose. Rubber shoes, wires, cables, insulating rubber parts. Latex products and other rubber products and various automotive rubber parts production areas, especially the production of Radial tire. Can Make Meridian, steel wire and rubber stick more solid. Effectively prevent the compound spray, improve the heat resistance of the tire.
