Dichtomatik Ltd, the sealing specialists, can now offer Viton® fluoroelastomer sealing products that have been subject to DuPont™ 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
Exceptional base resistance
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. As a customer focused supplier, they are able to offer full technical support, service and supply for specific applications in the aerospace, chemical processing, oil & gas, energy, utilities, automotive and heavy duty/offroad markets, together with the food and pharmaceutical Industries. Performance enhanced variations of Viton® Extreme™ products are also available to cover specific applications, while maintaining the superior processing attributes of the Viton® Extreme™ range.
Viton® Extreme™ TBR-S
A totally base-resistant Viton® polymer that utilises APA technology and a revolutionary bisphenol cure site for an improved TFE/Propylene copolymer.
This provides:
Inherent resistance to caustics/amines
Good resistance to hydrocarbon oils, acids and steam
Superior compression set resistance and lower volume swell for longer seal life and wear resistance
Superior processing versus other TFE/Propylene polymers
Viton® Extreme™ TBR-605CS
This elastomer can be used in oil and gas, chemical processing, utilities, automotive and heavy duty/off highway applications. Due to its chemical structure, like all other TFT/Propylene products, it is not recommended for automotive or aircraft fuel sealing.
Viton® Extreme™ ETP-S
This is an upgrade to ETP-900 that significantly improves processing and end-use performance, while retaining the excellent fluid resistance of its predecessor. It provides:
Excellent resistance to acid, hydrocarbon and low molecular weight esters, ketones and aldehydes
Inherent resistance to base attack and volume changes in highly caustic solutions, amines and hot water
Low-temperature flexibility (Tg -10°C)
Improved compression set and physical properties for superior seal performance
Better mould flow, faster cure rates, and improved mould release and fouling for efficient manufacturing
Viton® Extreme™ ETP-600S
While officially classified as an FEPM by ASTM D1418, the performance characteristics of Viton® Extreme™ ETP-600S combine the best characteristics of an FEPM and a specialty type Viton®. In complicated environments and chemically aggressive applications where standard FKMs or FEPMs are not an option, ETP-600S is the fluoroelastomer of choice. ETP-600S truly is the best of both worlds, with very low swell in hydrocarbons, it provides exceptional service for automotive oil seals and oil field applications, as well as automotive and aircraft fuels.
Dichtomatik is a leading worldwide supplier of sealing solutions to many diverse industries and is able to offer outstanding customer service and support. Working closely with DuPont™ Performance Polymers European technical centre in Geneva, the leading global supplier of speciality elastomers and supporting technologies, they are able to provide innovative solutions to help customers stay ahead of the competition.
The brand names Kalrez®, Viton®, Zalak® and Vamac® are all registered trademarks of DuPont™ Performance Polymers.
