CSI-AST1900
  
Anti-static Agent for polyolefins
Specification

Characteristics & Application
-Antistatic agent CSI-AST1900 is an internal antistatic additive that can be used in various polymers such as PE, LLDPE, PP, SAN and ABS. CSI-AST1900 gives sustained antistatic action and has due to its saturated alkyl chain excellent thermal stability. This makes CSI-AST1900 especially suitable for those applications needing higher processing temperatures.

- CSI-AST1900 is a solid at ambient temperatures. When heated at 60-70℃ CSI-AST1900 can be dosed as a liquid directly into the polymer by using a single or twin-screw extruder.  Pigment or color concentrates should be mixed with the antistatic agent prior to extruding. Premixing ensures uniform distribution of CSI-AST1900 in the resin while CSI-AST1900 acts as a dispersion aid to the pigment color concentrate.

- After being mixed into the polymer CSI-AST1900 continuously migrates to the surface of the finished product where it provides excellent antistatic performance. CSI-AST1900 is especially well suitable for those applications needing high processing temperatures.
