novatec®
Fiber-reinforced graphite gaskets
The link between fiber and graphite
novatec® brings two worlds together: The world of conventional fiber gaskets and the world of graphite gaskets. Their very high graphite content makes novatec® gaskets superior to conventional fiber gaskets due to the following properties:
Higher temperature resistance
Better chemical resistance
novatec® is ideal for higher requirements that conventional fiber gaskets cannot meet or no longer reliably satisfy. Thanks to their material structure, novatec® products have sufficient inherent strength so that a metal insert is not necessary for reinforcement. This makes them suitable for use with a variety of media.
Elastomer Guide - Transfer to KTW - BWGL
The validity of the elastomer guideline expires at the end of 2021. From 01 January 2022, the Elastomer Guideline (ELL) will be integrated into the KTW BWGL (Plastics in Drinking Water - Basis for Assessment) as Annex D. For the mandatory validity to meet the requirements according to the KTW BWGL, a transition period of 2 years is foreseen, i.e. until the end of 2023. Within these 2 years, test reports according to the previous elastomer guideline (and W270) may still be used to prove suitability.

The next generation of fiber-reinforced graphite gaskets
novatec® PREMIUM XP is the third generation of fiberreinforced graphite gasket developed by Frenzelit. novatec® PREMIUM XP is superior to conventional fiber gaskets due to its extremely high graphite content, which makes it extraordinarily resistant with excellent residual stress.
Sophisticated process technology is used in the production of ® PREMIUM XP. In addition, the graphite morphology has been optimized as the structure of the graphite also greatly influences the sealing performance. This targeted adjustment paired with the formula’s high density enables novatec® PREMIUM XP to achieve sealing category L0,01 in typical applications and thus meet the strict criteria of TA Luft and VDI 2290. DIN EN 1591-1 compliant gasket system designs are therefore no problem with novatec® PREMIUM XP.
novatec® PREMIUM XP closes the gap between conventional fiber and graphite gaskets and offers a true alternative for applications with demanding media and temperatures up to approx. 250 °C. The material is highly compressed and has above-average residual stress, so no metal reinforcement is needed. This lack of a metal insert has a positive effect on the chemical resistance.
novatec® PREMIUM XP gaskets can be manufactured with ease – even directly on site – using all standard methods.
Another feature of novatec® PREMIUM XP is its royal blue anti-stick coating, which is effective throughout the entire temperature range with long-term stability.
