COR Alpha is the most rugged photopolymer resin on the market. What do we mean by rugged? 

  • Unparalleled impact resistance (un-notched IZOD >800 J/m)
  • Very high working temperature (glass transition >150 °C)
  • Best-in-class ductility (> 20% elongation at break)
  • Extreme chemical resistance, including 10-100x lower moisture absorption than typical photopolymer resins
  • Grade 0 Cytotoxicity (ISO 10993-5)

COR Alpha is the most rugged photopolymer on the market
