R/W Heads and Data Carriers are constructed using both ABS resin and epoxy
resin. Referring to the following charts, be sure to use only those chemicals that
have no effect on the ABS or epoxy resins and avoid using those chemicals that
do have an effect.
Applications requiring explosion-proof capability are not possible.
ABS
The test results listed were obtained at room temperature (approxi-
mately 23°C). Some of the chemicals listed as having no effect may
cause problems at higher or lower temperatures.

acid (30% RT), acetic acid (50% RT), calcium hydroxide,
benzine, creosol, alcohol, cyclohexane, toluene, xylene,
benzine, grease
Ammonia, hydrochloric acid (10% RT), potassium
hydroxide, petroleum, gasoline, Yushiroken S50,
