PARALOID™ K-120ND

PARALOID™ K-120ND readily dispersible acrylic powder is designed to improve the processing of rigid and flexible vinyl, allowing compounds to fuse rapidly, flow smoothly, have excellent hot metal strength, and improved surface appearance.

Used in:

  • Specialty injection molding
  • Vinyl applications that require critical rheological properties
  • Blow-molding bottles
  • Rigid and flexible calendered film
  • Extruded construction products
  • Blown or extruded vinyl film

Advantages:

  • Clarity and excellent dispersion
  • Shortened fusion time
  • More homogenous melt
  • Excellent metal strength and parison control
  • Smooth, glossy surfaces free of surface imperfections
  • Increased output rates and improved production efficiency
