Silicone for Drinking Water Applications and Sanitary Technology

Our Expertise – High-Quality Silicone Articles for Drinking Water and Sanitary Technology

Modern sanitary and water technology faces diverse challenges. Clean drinking water, efficient wastewater systems, and comfortable sanitary installations are the cornerstones of our quality of life. In an era where environmental protection, energy efficiency, and health consciousness are becoming increasingly important, the demands on materials used throughout sanitary technology are also rising. Stricter legal regulations, new technical standards, and a growing awareness of hygiene are driving the demand for innovative and safe materials.

In sanitary technology, silicone is used in a variety of ways – from inner hoses of stainless steel braided metal hoses in heating and pump construction to seals in sanitary fittings and complex sealing systems in building technology. The background is not only the strict legal requirements of the Drinking Water Ordinance but also the growing demands for comfort, efficiency, and longevity of modern sanitary systems. Lindemann Silikon GmbH & Co. KG has established itself as a competent partner for the entire sanitary and water technology sector and has been developing specialized silicone solutions for the diverse requirements of this demanding industry for years.

Key Application Areas of Silicone in Sanitary Technology

Drinking Water Applications: Purity and Safety

Drinking water applications place the highest demands on material purity and safety. Our silicone hoses have been specially developed for direct contact with drinking water and comply with all relevant national and international standards. They are used in shower hoses, water pipes, and flexible connections.

Due to the physiological properties of silicone, especially the absence of plasticizers, the material is excellently suited for the drinking water sector. While other elastomers, such as certain EPDM compounds, tend to negatively affect the quality of drinking water above certain temperature ranges, silicone ensures constant purity and taste neutrality.

Sanitary Installations: Comfort and Reliability

Modern sanitary installations require components that are not only functional but also work reliably for decades. Our silicone molded parts offer optimal solutions for faucet seals, valve components, and connecting elements in bathrooms, kitchens, and other sanitary areas.

In mixer taps, thermostatic fittings, and electronic sanitary systems, silicone components ensure precise function and long-term tightness. Their resistance to limescale deposits and cleaning agents makes them the ideal choice for intensive use in private households and public facilities.
