The customer Return On Invest (ROI) period, a key development criterion, should be less than 3 years. The engineering team at SGL sees itself in the role of enabler, developing solutions that have not previously existed as such. Instrumentation with a PTFE liner supplied by SGL is a recent example. This relatively minor quality enhancement has a significant effect, says Wittchen.
“We are able to produce high-quality, uniform PTFE which enhances measurement precision.” Incidentally in the middle of 2007, PTFE expertise was brought on board with the acquisition of the fluoroplastic specialist Dr. Schnabel. The company produces pipe, tubing, expansion joints, containers, columns and silicon carbide heat exchangers which are lined with PTFE.
The Secret to Success for Special Graphites
PTFE linings for columns in the chemical industry are another business opportunity, and the Business Unit is likely to exhibit a material variant at the K plastics & rubber show which turns PTFE into a high-performance material, providing an exit pathway from the “plastic space”.
