Kostat BK-STAT
Categories:	Other Engineering Material; Additive/Filler for Polymer; Polymer
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 Dissipation Humidity Insensitivity No Particle Generation No Migration Excellent Colorability Good Processibility Applications: Semiconductor Packaging LCD Packaging Electrical & Electronics Medical Devices Storage Disks Appliances Consumer Goods Clean Room Accessories
