Part of the Flexitallic Group, the Flexitallic GmbH Service Centre and warehouse operates out of Willich, Germany and offers Specialist Sealing Solutions, Application Consulting and Engineering Services, to meet the bespoke gasket and seal requirements of customers across Germany and Europe.

Manufacturing capabilities at Flexitallic GmbH include Spiral Wound Gaskets, Kammprofile Gaskets and Flat Gaskets, along with large stocks of finished goods and in-house gasket cutting facilities.

Process temperatures are rising and operators are looking to extend maintenance intervals. This requires gasket/sealing materials suitable for high temperature applications up to 1000°C which offer safe, long term reliability.

To address these issues, Flexitallic developed a material which has the same gasket sealing characteristics of graphite but the thermal resistance of mica – Thermiculite^® high temperature gasket materials.

Suitable for use in critical sealing applications, Thermiculite^® has a proven track record in fertilizer, nitric acid, ethylene, reformer and ammonia production, and is available as a gasket sheet, spiral wound gasket, kammprofile gasket, Change™ gasket and valve stem packing.

Due to the cyclical nature of temperature ranges handled by shell and tube heat exchangers, Change™ was originally developed by Flexitallic as a heat exchanger gasket, in response to customers’ long-term sealing problems.

Proven to outperform all other gaskets, Change™ has high recovery properties, without comprising tightness, which is essential in high temperature, thermal cycle applications.

Other typical Change™ applications include boiler manhole gaskets, damaged flanges, reactor seals (FCC, coker, hydrogenation, ethylene/fertilizer production).

Utilising a unique manufacturing process exclusive to Flexitallic, SIGMA^® represents the latest generation of multidirectional PTFE materials, which offer very high chemical resistance in processes ranging from cryogenic temperatures to 260°C.

All SIGMA^® materials and PTFE filled seals/gaskets are FDA compliant, making them ideal for use in industries where product contamination is of concern.

Sigma 500 blue – PTFE modified with hollow glass microspheres. Enhanced compressibility for low bolt loads. Designed for glass pipelines, plastic and thin or distorted metal flanges.

Sigma 511 fawn – PTFE modified with silica filler. Suitable for strong acids (except hydrofluoric) and general chemicals.

Sigma 533 white – PTFE modified with barium sulphate. Suitable for strong alkalis and other general chemicals.

Sigma 588 sandwich – PTFE material with low stress characteristics, ideal for low load sealing in damaged flange surfaces. Used in both concentrated acid and alkali service.

Sigma 600 white – PTFE material with low stress characteristics and high compressibility for ultra low bolt loads; plastic and glass lined equipment. Universal material suitable across a wide range of chemical media.

Sigma 800 ePTFE – Expanded PTFE sheet material with enhanced low stress sealing characteristics and improved blow-out resistance and is suitable for sealing most chemicals across the pH range.

Our team of application engineers understand that the use of high quality seals/gaskets are not a guarantee of sealing success. As a result, Flexitallic application engineering offer a range of Joint Integrity and Technical Services that are designed to complement and enhance Flexitallic’s product offering.

Allowing customers to operate their plants, complete projects and start up from turnarounds safely and efficiently. Our goal is to help customers achieve leak free start-up and operation within the scheduled maintenance cycle.
