o Popular for its Thermal Properties
o Provides excellent Thermal insulation and is commonly used in cold chain segments
Polyurethane is a softer, open-cell type of foam that is made in varying degrees of firmness. Because the cells are open and not cross- linked, air can flow throughout the foam just like water can flow throughout a sponge. This characteristic makes the foam softer and gives it the ability to absorb shock energy better. It does not try to rebound as quickly as polyethylene, and it distributes the energy of the compression more broadly.
