Gummiwerk Kraiburg expands offering with FFKM compounds

The German company Gummiwerk Kraiburg GmbH & Co. KG in Waldkraiburg has expanded its product portfolio to include perfluoroelastomer (FFKM)-based compounds to meet the increased requirements for chemical resistance and thermal stability.

Applications include high-performance perfluoroelastomer products such as seals and membranes. These compounds are used primarily in the chemical industry, mechanical engineering and aeronautics. According to the company, the stringent requirements of these applications make robust seal solutions an absolute “must”. Perfluoroelastomer compounds from Kraiburg are said to enable the implementation of durable seal applications, which contribute to higher productivity and sustainability.

One of the major advantages of this product group is the much improved chemical stability compared to fluoroelastomer compounds, says Kraiburg. Perfluoroelastomer compounds can be used at continuous temperatures of more than 300 °C. In addition, their compression set at temperatures above 200 °C expands the spectrum for demanding seal applications. FFKM compounds are most commonly processed by means of compression moulding—injection moulding can be used as well.

Gummiwerk Kraiburg GmbH & Co. KG, a company of the Kraiburg Holding GmbH & Co. KG, currently employs over 410 people and achieved turnover of EUR 95 million in 2014. Kraiburg compounds are used in the automotive industry, in mechanical engineering, the food industry, oil and gas production, roller production and by numerous manufacturers of other moulded rubber parts. The company develops and produces rubber compounds, individually customised to the customer’s requirements. The compounds are based on standard elastomers such as NR, EPDM, NBR or CM, as well as fluoroelastomers and silicone elastomers.
