Effect the corrosion resistance of various types of PTFE under concentrated strong acid and high temperatures conditions: A preliminary study.

In this research, corrosion properties of assorted types of PTFE were examined under concentrated strong acid and high temperature condition. The most optimum type from the test results will then be used as a coating material for high temperature reactors using the hot press method, which are intended to be used as a coating on tin sulfate production reactor. PTFE was examined using sulfuric acid 96% by immersion and steam method at 250°C. The result shows that the PTFE sheet possesses the least affected by concentrated sulfuric acid corrosion, with 0.0116% corrosion per hour. In addition, PTFE sheet has been successfully coated on high temperature reactor. [ABSTRACT FROM AUTHOR]
