Hydel ® PC-7 ESD
Static Dissipative Polycarbonate DatasheeT
DESCRIPTION
Hydel ® PC-7 is a polycarbonate base
material that has been filled with graphite "nanotube" microfibers to
provide static dissipative properties. Unlike conventional carbon products,
this technology allows for superior dimensional stability after machining,
consistent electrical properties, excellent surface quality, and minimal
sloughing. This material has superior workability and more consistent filler
dispersement than competitive equivalent products.
Hydel ® PC-7 is black
in color and is available in sheet, rod, tubular bar and profile
forms.
