Sponge rubber is a porous material with pores throughout the entire structure, characterized by its low density, good elasticity, and high flexibility, and it also offers shock absorption, noise reduction, and thermal insulation properties. Its pore structures can be classified into open-celled, closed-celled, mixed-celled, and micro-celled types. The raw materials include natural rubber, synthetic rubber, and rubber-plastic blends. It can be manufactured into soft or hard rubber products, made through vulcanization after adding foaming agents. This material is used in various fields such as automotive, construction, household appliances, clothing, footwear, dyeing and printing, fitness equipment, and ion exchange, for the production of seals, shock absorbers, soundproofing layers, wetsuits, surf suits, beach shoes, and sports mats, among others.
