VINNEX® LA 2540 is a solid, thermoplastic polymer granulate. The clear, yellowish polymer is based on vinyl acetate and polylactic acid. It is designed as an additive for the application in biodegradable plastic formulations.


VINNEX® LA 2540 provides the following advantages to processing of biodegradable plastics (PLA: PHA; PBS, PBAT, starch, CA):

  • 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 extrusion, injection molding and film processing applications.


VINNEX® LA 2540 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 2540 can be mixed with the other solid raw materials of the bioplastic formulation.
