Chemical Compatibility List, NOVATEC 825F, 925F and Premium
 
How To Use It
You can safely use this list, using the PxT values as the limits for your gasket applications where no limits are shown. If your gasket application has an unusually high percentage of a harsh chemical, we recommend you review your gasket application data with us first.

Pressure x Temperature = PxT value. The pressure x the temperature of your application should not exceed the PxT values below. Your application's maximum temperature and pressure cannot exceed the limits of our materials.

PxT Values

Thickness 1/32" 1/16" 3/32"
NOVATEC 825F 400,000 350,000 210,000
NOVATEC 925F 600,000 600,000 260,000
NOVATEC Premium
700,000
650,000
275,000
For 1/8" thick applications, a PxT value of 210,000 for the 825F and 260,000 for the 925F can be used when the gasket has a minimum flange width of 1.25". Remember thicker is not better. As in all compressed sheet the PxT values decrease significantly as the thickness increases.
Chemicals Not Listed Or Shown To Be Incompatible
Chemicals not listed are not necessarily incompatible with this sheet. Application criteria could alter our recommendations where we show limits. So please phone us at 800 825 0031 with your gasket application data.

The temperature up to which a gasket functions satisfactorily depends on the media, internal pressure and flange loading. The figures shown should be regarded as maximum values. 

Sealing the operating pressure depends not only on the gasket material but also on the flange assembly procedure. The values shown are for guidance only. The following factors are of great influence: type of flange, available gasket stress, the flange assembly, working pressure, quality of mating surfaces and the media.

Warning: Properties/applications shown throughout this brochure are typical. The ASTM classification numbers and accompanying typical values are based on ASTM testing of .031" thick material, and values for other thickness may vary. The above application list is intended only as a guide, and Frenzelit recommends that testing be performed in your application prior to approval. Failure to select the proper sealing products or improper installation could result in property damage and/or serious personal injury. Please call your sales representative for more information.
