Chambroad Sinopoly

Founded in 2019, Jingbo Zhongju is a high-tech enterprise under Chambroad Holding Group, specializing in the R&D, production and sales of butyl rubber and halogenated butyl rubber. Relying on independently developed advanced production processes, it has built a domestically leading butyl rubber production line. Its product range covers ordinary butyl rubber, halogenated butyl rubber and other categories, which are widely used in tire inner tubes, automotive seals, food and pharmaceutical packaging seals, photovoltaic module seals and other fields. The company provides high-quality elastomer material solutions for the global rubber and plastic industry.

Butyl rubber Halogenated butyl rubber independently developed
R&D Strength
Technological Breakthroughs

Overcoming key technologies such as butyl rubber polymerization reaction control and halogenation modification, breaking the technical barriers of foreign enterprises in the field of high-end halogenated butyl rubber, and the product performance has reached the international advanced level.

Patent Achievements

More than 30 patents have been applied for in total, with core patents covering key links such as butyl rubber catalyst preparation, production process optimization and product application development.

Team Configuration

The R&D team is led by doctors and masters in the fields of polymer materials and chemical engineering, and has formed a technical research group in cooperation with experts from the Chinese Academy of Sciences and universities. Over 35% of technical personnel hold intermediate or senior professional titles.

Scientific Research Platform

Relying on the national-level enterprise technology center of Chambroad Group, it has built a special butyl rubber laboratory, pilot test base and performance testing center, with full-process technology transformation capabilities from laboratory small-scale testing to industrial mass production.

Global Layout
Key Markets

As a core pivot in Europe, we are simultaneously planning the layout of overseas warehouses in Southeast Asia and South America, and linking them with local warehouses in China to form a nationwide coverage network.

Product Positioning

Focusing on high-end halogenated butyl rubber (bromobutyl rubber, chlorobutyl rubber) to meet the demand of overseas tire enterprises for high-performance sealing materials, while providing ordinary butyl rubber as basic supporting products.

Cooperation Mode

Establishing long-term supply cooperation with large overseas tire manufacturers, providing customized product formula adjustment services, and setting up overseas technical service stations to quickly respond to customer needs.

Future Planning

Planning to layout warehousing and distribution centers in Southeast Asia to shorten the product delivery cycle; promoting products to obtain international certifications such as EU REACH and US FDA to further expand the European and American high-end tire markets.
