PTFE (Teflon) - ePTFE joint sealant for food and pharma


KWO® Universal-F premium

KWO® Universal F premium is a gasket tape made from mono-directionally expanded PTFE and is especially suitable for food and pharmaceutical industries This soft gasket material adapts very well to the sealing surface and is characterised by a low cold-flow tendency and a high tensile strength.

This gasket tape is particularly suitable for uneven or damaged sealing surfaces. The tape allows a wide range of applications, regardless of the shape and the size of the sealing surface. Being self-adhesive on one side, the tape can be attached easily and quickly. The used glue is suitable for applications in the food industry.

The gasket tape can be used to seal surfaces of any shape: pipe flanges, flanges of apparatus and tanks, pumps, fittings, compensators and ventilation facilities.

Another advantage of the gasket material is its versatility, being suitable for applications in almost all industry sectors, notably in the food industry and in the pharmaceutical manufacturing sector.
