Plastistrength® 576

Plastistrength® process aids

Plastistrength® 576 acrylic process aid is an advanced high molecular weight acrylic process aid that offers outstanding melt strength, excellent melt elongation, and enhanced fusion promotion. Plastistrength® 576 acrylic process aid can be used to promote fusion in highly filled vinyl compounds or used to reduce extrusion temperature without compromising fusion performance.


  • Reduced vinyl yellowing improving product quality 
  • Increased stability of PVC compound
  • Energy cost reduction
  • Prolonged extruder or injection screw life
  • Quicker downstream cooling offers potential for line-speed increases
  • Use with incumbent chemical foaming agent (CFA) or provides opportunity for further CFA optimization
