"PD" POLYMER CHEMICAL COMPATIBILITY CHART
DISK DRIVE INDUSTRY

OVER 15 YEARS OF PROVIDING STATIC DISSIPATIVE HANDTOOLS
TO MEET THE STRICT SPECIFICATIONS OF THE DISK DRIVE INDUSTRY.

The chart below provides an alphabetical list of chemicals along with our best general recommendations regarding their compatibility with PD Polymer Compound. The criteria for "Acceptable" compatibility ratings are the expectation that PD Polymer Compound would retain at leas 50% of original mechanical strength and exhibit less than 3% swell after exposure to the chemical for one year at 93°C (200°F). Although we caution against extensive exposure to some chemicals at elevated temperatures, brief exposure to those chemicals at elevated temperatures, or long-term exposure to those chemicals at near ambient temperatures should be acceptable. "Avoid Exposure" recommendations indicate that we do not recommend using PD Polymer Compound in service with those chemicals except under the limitations cited.
