Property Comparison
Working pressures are at 73°F (23°C). Pressure ratings are also effected by diameter of tubing and wall thickness. Actual performance may vary with different
media and working conditions. Use this information for comparison only.
The table below lists a generally accepted summary of properties that we believe to be reliable. Please note that many
of these resins are produced in several varieties and property characteristics may vary. Therefore, determination of
resin is dependent on the application and this table is only meant to serve as a general guideline.
