Encapsulation of low mp salts
ICL Innovation is seeking a technology for the encapsulation of inorganic salts and salt hydrates having melting point lower than 150°C within a non permeable thermoplastic polymer shell to form encapsulated salt pellets.
Key Success Criteria:
- The inorganic salts should be encapsulated in a polymer which does not allow leakage
- The polymer must have a Water Vapor Transmission Rate (WVTR) equal or lower than that of polyethylene.
- Salt to polymer ratio should exceed 85% w/w
- Matrix should be stable over prolonged period of time
- Encapsulated salt pellets should be in the diameter range of 0.5 – 5 mm
- Encapsulation would be tested with the following inorganic salts: CaCl2.6H2O, CaCl2.6H2O + MgCl2.6H2O, MgCl2.6H2O, MgCl2.4H2O, MgSO4.10H2O, Na2HPO4.12H2O, CaBr2.6H2O and Na2P2O7. 10H2O. Potassium based salts may also be tested.
- Economic viability
ICL produces a range of salts from both the Dead Sea and quarries around the world. Molten salt mixtures which offer enhanced properties, and are based on these materials would strengthen ICL's position in the various markets. The use of encapsulation further expands possible heat storage applications, such as construction materials.
