Sponge rubber is a porous material with pores throughout the entire structure, characterized by its low density, good elasticity, and high flexibility, offering shock absorption, sound insulation, and heat insulation properties. Its pore structure can be categorized into open-cell, closed-cell, mixed-cell, and microcell types. The raw materials include natural rubber, synthetic rubber, and rubber-plastic blends, which can be processed into soft or hard rubber products. These are produced through the addition of foaming agents and vulcanization processes. This material is used in various fields such as automotive, construction, home appliances, clothing, footwear, dyeing and printing, fitness equipment, and ion exchange, for manufacturing products like seals, shock absorbers, soundproofing layers, wetsuits, surfwear, beach shoes, and sports mats.
