Opteon™ 1100 Materials Compatibility
Opteon™ 1100 demonstrates superior material compatibility compared to HCFO-based foam blowing agents, notably when it
comes to refrigerator liners (ABS and HIPS). Materials compatibility testing over 14 days showed that Opteon™ 1100 is also
compatible with typical metals, elastomers, and plastics, as indicated by negligible weight, volume, and hardness change.
