In both of those situations the first insulating materials is air, and also the polymer used for trapping the air is organic keratin protein.
In sector, energy should be expended to lift, lessen, or maintain the temperature of objects or method fluids. If these are typically not insulated, this improves the energy prerequisites of the method, and thus the cost and environmental impact.
In the two instances the principal insulating material is air, plus the polymer employed for trapping the air is all-natural keratin protein.
