Applications
Ionphase™ U1 is designed to be used in compounding, injection molding and extrusion applications with PC blends. Examples of end applications are electrostatic discharge (ESD) protection for covers and housings in electronics, dust prevention for automotive interior parts and dust prevention in consumer appliances.

Mode of action
Ionphase™ U1 is a static dissipative, polymeric polymer additive commonly known as a permanent antistatic additive. These additives are used to control static electricity in plastics. This works by forming an interpenetrated network within the host polymer reducing the resistivity of the blend.

Benefits

• Permanent non-migrating anti-stat

• Not humidity dependent

• Static dissipative

• Gives control and safety for static electricity caused issues

• Lowers the surface resistivity

• Improves the non-charging properties

• Reduces charge decay time

• No halogens, RoHS approved

• Recyclable

• Ready to use and compatible with host polymer

Recommended Polymers

• PC blends

• PBT

• PMMA

• TR-ABS

• TPU

Guidelines for use
Ionphase™ U1 is normally processed between 230-280 °C. Actual processing temperatures will usually be determined by specific equipment or host polymer. We suggest adding the material as an additive during the extrusion process. Compounding into the host polymer is highly recommended before injection molding. Use of a
barrier type screw with good mixing properties is recommended for good homogeneity of the polymer blend. Stainless steel with nitration, duplex chrome or nickel plating is recommended for screws, barrels, dies and adapters. Low MFI polyethylene is recommended for purging after using Ionphase™ U1. The required loading of Ionphase™ U1 will depend on the host polymer, processing method and the targeted level of static dissipation.
