Industrial Solution

Star-branched halogenated butyl rubber SIIR

High strength branched

SIIR Star-branched Halogenated Butyl Rubber, with simultaneous improvement in mechanical properties and processing performance, is mainly applied to high-end sealing components in Sealing & Shock Absorption, balancing strength and processing efficiency.

Branched structure improves tensile and tear strength
Higher processing efficiency, shortening vulcanization time
Air tightness is better than that of conventional butyl rubber
Resistant to flexural fatigue, suitable for high-frequency vibration scenarios

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.
