Our proprietary materials offer a versatile selection of sealing materials that are optimised for various industrial applications. NT-Chem Beige and NT Chem Blue are specially developed for use in chemical environments. NT Chem Beige is characterised by high creep strength and chemical resistance, ideal for demanding conditions. NT-Chem Blue, on the other hand, offers outstanding flexibility and is particularly suitable for applications with sensitive flange connections made of glass and ceramics.
NT-Classic and NT-Unit are universal sealing materials that are characterised by a good price-performance ratio. NT-Classic is ideal for general industrial applications, while NT-Unit with its high gas tightness and stability is ideal for gas and water supply.
NT-Flex is the first choice for high-purity and chemically demanding applications. With its universal chemical resistance and flexibility, it is particularly suitable for applications that require high purity and resistance.
Overall, these materials offer the right solution for every specific requirement, whether in the chemical industry, mechanical engineering or food production.
