Material Notes:
BK-STAT is an inherently dissipative polymer incorporated into a variety of resins as a melt additive. The electrical resistivity is reduced by formation of a conductive percolating network in the host resin. This is a permanent, non-migratory anti-static agent. This additive is also thermally stable and effective at low humidity levels.The recommended use levels are 10-25% and surface resistivity of E8-12 ohms/square can be achieved.Special Features:Superior Permanent Static DissipationHumidity InsensitivityNo Particle GenerationNo MigrationExcellent ColorabilityGood ProcessibilityApplications:Semiconductor PackagingLCD PackagingElectrical & ElectronicsMedical DevicesStorage DisksAppliancesConsumer GoodsClean Room Accessories
