click to resize photo Tecaform ® SD (formerly known as Hydel ® ASD) is an acetal base material that has been filled with an inherently dissipative polymer (IDP) additive. IDP's have no carbon or graphite content and do not slough conductive particles. This material has consistent electrical properties, good wear resistance, broad chemical resistance, and machines very easily.

Tecaform ® SD is  NATURAL (tan or ivory)   in color and is available in sheet, rod, tubular bar and profile forms.
