Expertgel 412 is a copolymer presenting PEO/PPO/PEO blocks with organic linking. It is a thermosensitive gel, with reversible gelation. It behaves as a liquid at ambient temperature and jellifies when the temperature increases. Expertgel® 412 has a gelation temperature under 15°C and below 21°C. It is unaffected by pH changes.
