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.
Chemicals that Cause Warping, Cracking, Etc.
