Abstract: A thermal insulating additive, product formed therefrom, and method of making the same, wherein the thermal insulating additive comprises a plurality of hollow polymeric particles having an average particle size up to about 0.3 micrometers. The hoi low polymeric particles exhibit a mechanical strength in a compression test up to about 420 psi and a thermal conductivity that is less than 0.150 W/m-k. The hollow polymeric particles are individually formed as an alkaline swellable core that is at least partially encapsulated with two or more shell layers; the alkaline swellable core prior to swelling exhibits an average particle size that is less than about 50 nanometers.
