PTFE yarns and fibers specific yarn constructions for safe applications

A seal packing that is characterized by its smooth, supple surface and thus avoids wear on the valve stem due to an extremely low coefficient of friction. This ensures a reliable seal with minimal actuating forces. The natural elasticity of PTFE silk yarn enables easy handling and assembly, this means it flexibly adapts to various valve and shaft surfaces.

Confidence in quality and purity. A valve packing that retains its strength and integrity over a wide temperature range, making it suitable for use in food industry applications. There are no soluble contents such as oils. The surface is finely braided and seals against components even without much preload. The construction is basically extrusion resistant, which allows it to withstand even higher pressures and demands.

The S 6 Eco Silk Yarn Packing is characterized by its exceptional resistance in rotating applications. Its pliable and readily compressible quality provides a reliable seal. The packing exhibits good emergency running properties and is gentle on shafts, with a recommended surface hardness of HRC 25. A particular advantage is its resistance to aging. The S 6 Öko is also available in a variant as S6 PA with food approval as well as FDA-compliant.

Thanks to its perfect material combination of 100% PTFE fiber, special PTFE dispersion and FDA-compliant food-grade silicone oil impregnation, the S6 SI is an outstanding choice for applications requiring purity. The properties of this packing make it not only ideal for general industrial applications, but also particularly suitable for demanding applications in the food and pharmaceutical industries.
