Buying advice

Consider density, closed vs open cell, and temperature resistance based on your specific application. For cushioning, high-density polyurethane is best; for insulation or flotation, closed-cell foam is ideal; for high heat, silicone sponge. Always check the exact dimensions and adhesion compatibility with other materials.
