Encapsulant compositions and methods for treating spills of hydrophobic and/or hydrophilic materials

摘要

Described are preferred encapsulant compositions, devices and methods for treating spills of hydrophobic organic liquids. Preferred compositions include one or a blend of powdered thermoplastic elastomers, along with a flow agent. Additional preferred encapsulant compositions include a powdered thermoplastic elastomer combined with a superabsorbent polymer. Devices for spray application of such encapsulant compositions include a vessel (11) adapted for forcibly spraying a powder, and a powdered encapsulant composition (12) contained in the vessel. Methods for treating spills of hydrophobic organic liquids involve the application of encapsulant compositions as described.
