|
Carbon powder-filled,
self-lubricating, moisture-repellent material with resistivity
levels in the 105 - 109 range. This
material has the highest impact strength, is lightweight, has
excellent abrasion resistance, and possesses good chemical and
stress-crack resistance.
The following physical property
information is based on typical values of the resin.
