Chemical Compatibility Chart

The chart below provides an alphabetical list of chemicals along with our best general recommendations regarding their compatibility with Ryton® PPS compounds. The type face in which the chemical name is printed indicates the extent of available test data:

Bold Face
We have extensive, long-term test data on compatibility of Ryton® PPS with these chemicals.

Normal Black Type
We have limited, short-term test data on compatibility of Ryton® PPS with these chemicals.

Gray Type
We have no actual test data on compatibility of Ryton® PPS with these chemicals, and our recommendations are based on our knowledge of the compatibility of Ryton® PPS with similar chemicals.

Chemical compatibility is expressed in four general classifications:

Acceptable
Ryton® PPS is expected to be suitable for extensive exposure to these chemicals, even at elevated temperatures. Ryton® PPS compounds would be expected to retain at least 50% of original mechanical strength and exhibit less than 3% swell after exposure to these chemicals for one year at 93°C (200°F).

Questionable at Elevated Temperatures
We caution against extensive exposure (continuous, long-term immersion) of Ryton® PPS to these chemicals at temperatures above 65°C (150°F), because excessive swelling or softening of the plastic may occur. However, brief exposure to these chemicals at elevated temperatures, or long-term exposure to these chemicals at near ambient temperatures, should be acceptable.

Avoid Use of Mineral Filled Grades
These chemicals are highly acidic and would be expected to dissolve common mineral fillers. Although compounds containing mineral fillers should not be used, unfilled Ryton® PPS or 40% glass filled Ryton® PPS compounds are expected to be suitable for extensive exposure to these chemicals, in most cases even at elevated temperatures.

Avoid Exposure
We do not recommend using Ryton® PPS in service with these chemicals except under the limitations cited. Although extensive exposure (continuous immersion) is not recommended, brief exposure (such as washing or splash) should be acceptable in most cases.

Testing under conditions as similar as possible to actual service is recommended to confirm the suitability of particular Ryton® PPS compounds for particular applications.
