Mass passenger transport systems require a very high degree of fire safety. With the entry into force of the new standardized European standard for rail vehicles EN 45545, the requirements have become substantially more stringent in comparison with DIN 5510. With respect to elastomers it is not easy to meet these higher standards. The company Gummiwerk Kraiburg has responded to the challenge by developing a Kraibon type that fulfills the requirements of the highest level. DB Systemtechnik Brandenburg tested this Kraibon elastomeric compound and awarded it the certificate for level R1HL3. Furthermore, Kraibon successfully certified in accordance with fire safety standard EN 45545.

The Kraibon family of highly innovative elastomers has been developed for composite applications and as the basis for use in rail traffic and aerospace industry. The new compound can be used in fact to manufacture very lightweight and sound-absorbing components and linings. The life of components subject to impact is increased significantly. Especially with a view toward the ongoing heated debate on saving energy, this is an essential step in saving weight and therefore costs and energy.

Belonging to the Kraiburg Group, Gummiwerk Kraiburg currently employs about 400 people and achieved turnover of about 110 million euro in 2013. Its compounds are used in the automotive industry, mechanical engineering, food industry, oil and gas production, roller production and by numerous manufacturers of other moulded rubber parts.
