Description
Forte
Heat resistance guide: 200°C
Standard hardness (Duro A): 70
General-use fluoro elastomer can be used for quickly degrading, high-temperature inorganic acids, steam, and sodium hydroxide.
There is almost no elution of the metal from chemical solutions.
Application
Cleaning equipment, wet etching equipment, filters, etc.
Eluted metal measurement results
As fluoroelastomer FB is not a compound that contains metal, it experiences a lot less metal ion elution than that of fluoroelastomer FA.
Test conditions
Pre-cleaning
After cleaning with 5% hydrofluoric acid, it is cleaned with ultrapure water.
Elution
Test specimen: O-ring P16 (thickness Φ2.4 × inside diameter Φ15.8)
Chemical solution: 50% hydrofluoric acid 300 g
Temperature × time: 24°C × 72 hours (3 days)
Analysis method
ICP-MS
