Plastistrength® 580

Supplied byArkema- Last Updated on Nov 6, 2025

Plastistrength® 580 by Arkema is an ultra-high molecular weight acrylic processing aid. It provides exceptional melt strength. It shows excellent foam density and cellular structure, with a quality surface finish, for cellular PVC building products.
  • It offers excellent value in formulations by increased efficiency and dosage reduction compared to traditional PVC process aids.
  • It maintains smooth surface finish after extrusion, allowing for exceptional weatherability and paintability.
  • It is recommended for all vinyl foam applications.
  • It can be used at reduced loading levels in deck boards, thin cellular PVC sheets, foam core pipe, and foamed moldings and maintains the needed final properties.
  • It gives more uniform and finer cell structure after cell nucleation by capturing an optimum amount of gas evolved from the blowing agent component.
  • Plastistrength® 580 is designed for use in thick PVC foam sheet but also effective in other applications.
