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.
