Surface Crosslinking of Polypropylene Copolymers using E-beam Technology

Request Number N779735
Author Kevin Andrews
Need details

Yanfeng Automotive seeks methods to crosslink the surface of polypropylene copolymer, at a controlled depth, using electron beam technology.


Yanfeng Automotive would like to improve surface durability of polypropylene copolymers without requiring the use of conventional polymer coatings.  Instead, they seek to modify the surface of molded parts.


Key Success Criteria
  • Ability to control depth and density of crosslinking.
  • Ability to process 3D surfaces and contours.
  • Process does not affect surface appearance and gloss.
  • Process is not capitally intensive.


Possible Approaches

Systems that operate at atmospheric pressure


Approaches not of interest

Paint and coatings, approaches that require changes to polymer formulation


Preferred Collaboration types
  • To Be Negotiated

My first thought in reading this always come from the point of: How can this material, however you end up modifying the polymer surface, how can this material be recycled?
Is it possible to crosslink CoPoly PP and then have a method of successfully recycling the production scrap?
