RepelShell® for Plastics

RepelShell® is a unique plastic additive that is able to transform the surface properties of plastic to become highly hydrophobic and oleophobic. A very small amount of the additive is all that is needed to lower the surface energy of a plastic part.

how RepelShell® plastic additive works

  • A thermally-stable plastic additive that works in most plastics and is compatible with injection molding and extrusion (including synthetic fibers).
  • Requires a very low weight loading percentage (1% - 5%) to make plastic repellent to water, oil, dirt and stains.
  • The additive migrates to the surface maintaining the mechanical properties of the plastic.

RepelShell® Plastic Additive Technology Explained and Demonstration

making surfaces of plastics repel water, oil, dirt and stains

This additive works in most plastics without impacting the mechanical properties of the host resin.

RepelShell® Additive of Plastics is a solid material this added to plastic to transform the surface area to become hydrophobic and oleophobic.  This additive migrates to the surface and then self-orientates creating a uniform layer.  The additive is specially formulated to be anchored into the plastic. As a result, the repellent properties of the RepelShell®  Additive  for Plastics will last as long as the finished part because they are embedded in the host resin.

The compounding process produces hybrid pellets that are used to inject, mold or extrude a part

applicable for plastic surfaces that need to repel water, oil, dirt and stains

RepelShell® Additive for Plastics is intended for any plastic product surface that needs to repel water, oil, dirt, and stains. This additive transforms the outer layer of a plastic part into having a lower surface energy and in return keeps plastic products looking like new, longer.
