At Achema 2015, DuPont presented innovative and sustainable solutions for boosting the safety, efficiency and reliability of chemical manufacturing systems. These include Teflon fluoropolymer resins and industrial coatings, Viton fluoroelastomer seals and Krytox high-performance lubricants. The company also exhibited ECCtreme ECA, a new high-temperature resistant, melt-processable fluoropolymer resin family capable of withstanding continuous service temperatures of up to 300°C. In a free seminar "Managing Corrosion with Teflon Fluoropolymer Resins" at the fair, DuPont explained the advantages of Teflon corrosion protection solutions with up-to-date case studies.

Enhanced corrosion protection Failures in chemical manufacturing systems caused by corrosion can lead to leakages, emissions, reduced processing efficiencies, increased costs and impaired product quality. Components made of Teflon fluoropolymer resins offer outstanding corrosion resistance over a wide temperature range, providing a solution that is often more universal and more economical than many exotic metals and alloys. Available in both powder and liquid form, they are suitable for a huge range of component sizes and shapes. Fluoroplastics are nonbrittle and are resistant to impact and thermal shock. Their low coefficient of friction assures ease of operation in moving parts such as ball or plug valves, while their inherent non-stick properties prevent deposits from forming and facilitate cleaning. Special grades of DuPont fluoroplastics have been developed to meet ATEX directives.

A new addition to Teflon® Industrial Finishes product line is the first truly water-based, low- VOC, easy-to-use 1-coat system based on Teflon PTFE. It provides outstanding corrosion protection while simultaneously ensuring sufficient slip to prevent galling, and is specifically designed for coating off shore, chemical processing, and water treatment fasteners on substrates such as carbon steel, stainless steel, and aluminum.

Highest temperature- and chemical resistance

ECCtreme ECA is a new melt-processable fluoropolymer resin family which combines the physical, electrical and chemical properties typical of fluoroplastics with very high heat resistance which means it is capable of withstanding continuous service temperatures of up to 300°C. It is suitable for sheathing cables, lines and sensors, for example in the recovery of geothermal energy, in the oil and gas industry and in aerospace applications.

Numerous grades of Viton fluoroelastomers are available which differ in terms of their chemical resistance and mechanical properties so they can meet requirements for specific applications and processes. With their wide heat resistance from –40°C to 200°C and their resistance to aggressive chemicals and motor fuels, they are suitable for seal applications in the chemical, automotive and general industry.

Free corrosion protection seminar

A seminar entitled "Managing Corrosion with Teflon Fluoropolymer Resins" hosted by DuPont during Achema 2015 explained the advantages of Teflon corrosion protection solutions. The seminar will focus on improved seal systems with longer maintenance intervals, specific case studies of linings or dust filtration solutions in chemically aggressive surroundings (e.g. waste incinerators), damage analysis and solutions as well as the new fluoropolymer resin family ECCtreme ECA from DuPont.  

High-performance lubricants for boosting operational reliability

Krytox high-performance lubricants offer a broad selection of specially formulated, nonflammable and chemically inert synthetic oils and greases which can help to ensure operational reliability in systems in the chemical and petrochemical industry without entailing any compromises in terms of lubricant action. Developed using DuPont technology to satisfy the special needs of the chemical industry, they are non-toxic, non-reactive, non-flammable, non-corrosive and compatible with the polymers used in seals, O-rings and valves. They retain their lubricant action and a stable viscosity over a wide range of temperatures in highly corrosive environments and can be used for lubricating valves, fans, pumps, agitators, reactors, centrifuges and other components.
