B-4 is a polyethylene sponge with a moderate softness. It has a texture similar to that of a kickboard. The method involves immersing it in melted PVC pool after punching it out to form a coating. Printing is also possible on the coated surface. It excels in insulation, water resistance, and chemical resistance, contributing to the safety and durability of the product.
