KURARITY™

KURARITY™ is a new series of acrylic block copolymers produced using Kuraray’s unique anionic living polymerization technology which combines various (meth)acrylates into AB or ABA type block copolymers. This controlled polymerization process enables KURARITY™ to remain exceptionally clean with minimal residual monomer or oligomer when compared to conventional acrylic polymers produced using radical polymerization. KURARITY™ is also referred to as MAM (Methyl-methacrylate- Acrylate- Methyl-methacrylate), and it consists of methyl methacrylate hard-blocks (PMMA-blocks) and an acrylic based soft-block. Due to this structure, this acrylic thermoplastic elastomer exhibits a variety of properties including excellent clarity, weather resistance, self-adhesion, and good compatibility with other polar materials.

  • Extremely low residual monomer or oligomer
  • Low hardness without plasticizer
  • Good compatibility with other polar plastics
  • Excellent mold-ability
  • Excellent weather-ability without concerns about hydrolytic degradation
  • Minimal/no odor
MAIN AREAS OF APPLICATION
  • Adhesives
  • Molded goods
