RubberCork / SuberSeal™
… nature’s solution to industry’s technical sealing, gasket and padding issues.
Jelinek rubber & cork products and materials are known as SuberSeal™. The word is derived from the scientific Latin name of cork which is Suber. The natural, renewable, and ecological brilliance of the ancient cork oak tree, Quercus Suber, combined with specified formulations of rubber properties form the ultimate 21st century gasket and sealing materials.
SuberSeal™ rubber & cork materials are offered by Jelinek for a variety of uses, among them:
electrical and transformer gaskets
flooring underlayment stress-crack prevention
general sealing and gasket needs
liners and spacers
surface protective pads
model train track beds
Production of “rubbercork” is relatively new. As the word suggests, the primary raw materials used is a mixture of cork and rubber specifically formulated to meet technical specifications and standards. Through extensive research and development during the mid 20th century, it was found that this unique mixture of materials created a product that is ideally suited for most sealing applications. R&D continues today allowing introduction of new and innovative binder and sealing technology. New formulation varieties fully utilize and maintain the natural characteristics of cork but when blended with the properties of rubber result in the most effective sealing gaskets and cushion pads. It is now well recognized that “rubbercork” combines the compressibility and resilience of cork with the high mechanical strength and dimensional stability of rubber.
A wide variety of formulations using different rubber types (natural rubber, synthetic rubber, nitrile, or neoprene) combined with different milled cork grain sizes are available to meet industry’s various requirements. It was not until the 1970’s that rubber cork became widely used throughout many major industries and today continues to be at the forefront of modern gasket technology. By combining decades of experience in the cork industry with modern day rubber technology, Jelinek successfully introduced SuberSeal™ as the 21st century’s primary gasket materials.
