Polycarbonate Chemical Compatibility

  • Chemically resistant to many acids, oxidizing / reducing agents, neutral and acid salt solutions, greases, oils, detergents, saturated, aliphatic and cycloaliphatic hydrocarbons and alcohols
  • Polycarbonate features an extremely high melting point, around 288°C / 550°F
  • Autoclavable
  • As a thermoplastic, PC can be heated to its melting point, cooled, and reheated without significant degradation
  • Superior impact resistance
  • NOT compatible with methyl alcohol, acetone, ketones, ethers, aromatic and chlorinated hydrocarbons, aqueous or alcoholic alkaline solutions, or ammonia gas
  • NOT ideal for food storage at temperatures above 70° (can release BPA)
