Rigid Polyurethane Foams produced from Green Polyester Resins are naturally better in performance than the conventional petroleum based polyethers when comparion to the Thermal Stability and Chemical Resistance.
LOW CARBON FOOTPRINT
Polyester-based urethans are more resistant to thermal degradation than the corresponding polyether-based urethans at temperatures in the range of 50° to 150° C. It has also been shown that this difference in thermal stability is due to irreversible, oxidative cleavage of polyether chain segments. By introducing up to 20% composition of MARINOH (a polyester polyol) into your polyether polyol system, the thermal degradation of end product rigid polyurethane foam will improved.
A greater consciousness has arisen in recent years for a need to protect and conserve our environment. Marinoh is an eco-friendly polyol that uses water as blowing agent thus, when incorporated to your petroleum-based polyol systems will result in an alternative green rigid PU foam. This inspires a movement towards development of green-hybrid systems in the Polyurethane foam industry.
