5:9 Container Material Proper1es

The most popular plas.cs are PFA and HDPE / LDPE:

§ PFA has excellent proper.es, allowing for use in acid diges.ons up to 250 ̍C.

§ Typically, PFA is used for acid diges.ons using either HF, HNO3 or HCl, alone or in combina.on.

§ The use of higher boiling acids such as H2SO4 and H3PO4 have been reported in PFA, but great care must be taken not to exceed the 250 ̍C maximum opera.ng temperature.

§ PFA is commonly used in the construc.on of microwave diges.on vessels. Microwave diges.ons using the higher boiling acids should not be aQempted.

§ Diges.ons using HCLO4 should never be performed in plas.cs of any kind.
