An encapsulated particle includes a core particle and a polyurethane disposed about the core particle. The polyurethane includes the reaction product of an aromatic isocyanate component and a polyol component. The polyol component includes a polyol derived from an aromatic amine-based initiator and an aliphatic polyether polyol. The polyol derived from the aromatic amine-based initiator has a nominal functionality of 4. The aliphatic polyether polyol has a nominal functionality of from 2 to 4. The weight ratio of the polyol derived from the aromatic amine-based initiator and the aliphatic polyether polyol is from about 1:2 to 2:1. A method of forming the encapsulated particle is also provided.
