SEALING SOLUTIONS FOR CHEMICAL APPLICATIONS
Knowledge, Challenges and Solutions
How to meet the challenges of sealing chemical applications and comply with the amended TA Luft.
Environmental and climate protection in conjunction with safety and sustainability are top priorities at Garlock. Not only should our sealing solutions meet the high demands that science and legislation place on us and our products, we also see it as our duty to do the corresponding educational work and offer our know-how to our customers. …

The customer’s application has a flange joint at the inlet/outlet of a plate and at the frame heat exchanger. One flange is glass lined and the other is coated with PTFE.
The customer had been using a silica filled PTFE, 2mm thick sheet gasket material. However, old and uneven flanges created leakage issues that the plant wanted to eliminate.
Due to the dangerous media being transported through the flanges there is a high risk of incidents and human harm, making it necessary for the gaskets to only be used once.
Extremely corrosive and toxic media, sulfuric acid and hydrogen peroxide, are being handled. In addition, several of the non-metallic (FRP) flanges were misaligned.
Using glass filled PTFE. The flange surfaces were being filled with epoxy when maintenance assessed the surfaces condition to be undesirable.
Customer’s need to consolidate to the fewest number of gaskets that would be good in chloralkali process media, metal lap joint flanges and FRP flanges. The customer also desired a gasket that would come in sheet form.
Ideally the customer desired one gasket to be used in all applications which included monomers, strong caustics and acids.
GYLON® offers a good possibility to use the advantages of PTFE, but due to its production process to eliminate the typical disadvantages – and even to improve the material. GYLON® is a modified and restructured PTFE.
Our solutions meet these requirements
In order to meet the requirements of special applications, we have subjected our materials and our GYLON® to special tests. These tests provide the basis for certification.
Patented hexagonal profile
The GYLON EPIX® hexagonal profile provides improved compressibility and recovery. The profiled surface reduces the contact area during initial compression to concentrate the compressive force and to generate high-density-zones within the material, for improved sealability.
Our experts are application engineers as well as sales engineers. All are highly trained and can discuss and debate the requirements of your applications with you professionally and expertly and advise you on the way to the best fitting sealing solution.
