Tecaform ® SD Static Dissipative Acetal
Datasheet
DESCRIPTION
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) in color
and is available in sheet, rod, tubular bar and profile forms.
