Abstract
A battery module comprising an electric cell and a potting compound associated with the electric cell. The potting compound is formed of a flame retardant component; a first component having an isocyanate reactive compound and water; and a second component having an isocyanate compound. The potting compound is a foam.
Claims20
A potting composition comprising:
- a first component comprising an isocyanate reactive compound and water;
- a second component comprising an isocyanate compound;
- and
- a flame retardant component in an amount greater than 10% by weight based on the total weight of the potting composition, wherein the flame retardant component is liquid at a temperature from 25° C. to 35° C.
