SOLKANE® 365 is the key component to form a range of promising blowing agent blends. For safety applications a non-flammable HFC-blend is of special interest. SOLKANE® 227ea is commercially produced propellant for pharmaceutical aerosols. Blends of SOLKANE® 365 and SOLKANE® 227ea have been checked for a flash point using an Abel Pensky closed cup flash point apparatus, in accordance to DIN 51 755-1. A blend of SOLKANE® 365/227 with 5 pbw of SOLKANE® 227ea has no flash point and is classified as a non-flammable liquid. It has to be pointed out that this blend is non azeotropic, and the compound SOLKANE® 227ea evaporates first during handling. To have a safety margin Solvay therefore recommends the blend SOLKANE® 365/227 with 7 pbw of SOLKANE® 227ea. This blend starts boiling at ~30 °C and is developed for foam producers. For System Houses Solvay developed the blend SOLKANE® 365/227 87:13, as the used polyols have an influence to the flash point behaviour. Although the blend SOLKANE® 365/227 has no flash point, it has flammability limits in air. Such a situation is well known with for instance SOLKANE® 141b or Methylene Chloride.
