Advanced seals offer high pH resistance

Sealing specialists Dichtomatik can now offer Viton fluoroelastomer sealing products that have been subject to DuPont's proprietary advanced polymer architecture (APA) technology.

These products, called Viton Extreme, feature base-resistant polymers to ensure improved long term performance in the presence of high pH chemicals.

Chemical solutions that have been introduced over the past few years incorporate bases which inhibit metal corrosion caused by the long term effects of acid build up. Chemicals used to clean or purge industrial and food processing equipment can also have strong bases which are similarly detrimental to the performance and life expectancy of fluoroelastomer sealing products. However, the DuPont high performance elastomers utilised for Viton® Extreme™ production are capable of meeting the highest challenges by providing overall fluids resistance, good base resistance and significant processing advantages compared to existing TFE/Propylene polymers.

Dichtomatik is an authorised DuPont licensee and approved UK source for all Viton, Vamac, Kalrez and Zalak O-rings, seals and finished products. The company offers full technical support, service and supply for specific applications in the aerospace, chemical processing, oil and gas, energy, utilities, automotive and heavy duty/offroad markets, as well as the food and pharmaceutical Industries.
