Adhesion Promoting Additive for Injection Molded Polyolefins

Request Number N74361
Need details
  • Additive for polyolefins that improves adhesion to its surface
  • Automotive grade polyolefins which includes PE, PP, TPE's, TPO's, and talc filled variants


  • Polyolefins have a low surface energy because they are very nonpolar and thus lack functionalities
  • Typical uses have been to use a primer that can have negative impacts on the environment
  • Other approaches are corona discharge, flame or plasma treatment to create CO functionalities on the surface


Key Success Criteria
  • Can withstand the high end of the processing temperature range ~440°F
  • Does not stick to the injection molding equipment or tooling
  • Does not volatize VOCs with an odor or health concern
  • Shows improvement via measuring the surface tension delta
  • Lower in cost than flame treating, < $0.20/ft^2 cost delta


Possible Approaches
What we are looking for?
  • An additive that is compounded into the polyolefin based formulations or that we can add at the injection molding press in the form of a masterbatch
  • Enables adhesion of these molded polyolefin parts to urethanes and acrylics


Preferred Collaboration types
  • To Be Negotiated
