RUBBER COMPONENTS FOR DRINKING WATER CONTACT

About this product

AVK GUMMI develops, produces and sells rubber components for drinking water solutions with high demands on quality and know-how and with focus on regulatory compliance. We produce customised rubber components for a wide range of applications – from the most simple products such as rubber gaskets in water taps to advanced, multiple-component liners for industrial drinking water systems.

Why our rubber solutions are suitable for contact with drinking water Rubber components for drinking water contact are subject to enhanced requirements as a number of factors may affect the quality of the drinking water. Therefore, we have particular focus on the following factors: - The rubber material must not affect the drinking water, e.g. by releasing taste, smell, colour or dangerous substances to the water. - The properties of the rubber material must provide optimal functioning, e.g. minimum permanent deformation, which ensures leak-tight gaskets. High resistance to wear, which ensures a long lifetime and low friction, enabling a low energy consumption when operating the valve. - High resistance to chemical processes used for water treatment, such as ozonation, chlorination and chloramination. - A low compound bio potential in order to limit the formation of biofilm.

Which type of rubber should you choose? Although rubber only constitutes a small part of the entire drinking water system, it is of vital importance for hygiene, water waste, functionality and the final outcome; the drinking water quality. Therefore, it is important that you choose the right rubber compound for your solution. At AVK GUMMI, we have almost 50 years of experience in developing rubber compounds and producing rubber components specifically for use in the drinking water supply. We use our experience to help you choose the right rubber quality for your product and the specific purpose. Our R&D department continually develops new, competitive rubber compounds, which means that we always offer you gaskets and drinking water solutions that are best in class.

The primary types of rubber for drinking water in our range are: - EPDM - NBR - HNBR

Consumer safety in a global perspective If your company operates in multiple markets, you know all about the challenge of complying with the different legal requirements, recommendations and standards for products that come into contact with drinking water. At AVK GUMMI, we manufacture rubber components for drinking water solutions based on compounds approved in most parts of the world. We send our rubber formulations to independent, accredited test institutes in a number of countries for testing and approval on an ongoing basis. This is your security that we consider local recommendations, standards and legal requirements – including compliance with lists of authorised substances and requirements concerning biofilm formation and the impact on drinking water quality. With AVK GUMMI as your partner, you will not have to spend time looking for local suppliers that live up to your expectations. Furthermore, with rubber compounds approved for drinking water in several countries, you will have a simple product programme and your tied-up capital in stocked goods will be reduced.

Drinking water approvals Drinking water compounds from AVK GUMMI is your guarantee that your rubber components will not release taste or odour to the water supply, and that the drinking water will not be contaminated with foreign matters from the rubber. With your own product design, e.g. a valve, or a gasket made of one of our compounds for contact with drinking water, you can be sure to have a fully functional product with a long lifetime.
