VINNEX® LA 8040 is a solid, thermoplastic polymer granulate. The colorless, semi-transparent polymer is based on vinyl acetate/vinyl laurate copolymer and polylactic acid. It is designed as an additive for the application in biodegradable plastic formulations.


VINNEX® LA 8040 provides the following advantages to processing of biodegradable plastics (PLA:, PBAT, starch,):

  • Processing of biopolyesters on conventional thermoplastic equipment.
  • Blending of biopolyesters with each other, easy homogenazation.
  • Increased organic or inorganic filler/fiber content without hardly sacrificing performance.

  • Improved performance and final product properties.
  • Improved processing and increased process speed, especially in 3D printing, film processing, injection molding and extrusion applications.
  • Reduces metallic noise of PLA



VINNEX® LA 8040 is recommended for modification of biodegradable polymers and compounds or their blending with natural or mineral fillers and fibres in dry mix applications.


VINNEX® LA 8040 can be mixed with the other solid raw materials of the bioplastic formulation.
