Honeycomb rubber is a porous material with holes throughout its entire structure, characterized by its low density, good elasticity, and strong flexibility. It also offers shock absorption, noise reduction, and thermal insulation properties. The pore structure can be classified into open-celled, closed-celled, mixed, and microcellular types. The raw materials include natural rubber, synthetic rubber, and rubber-plastic blends. It can be made into soft or hard rubber products, formed through vulcanization after adding foaming agents. This material is used in various fields such as automotive, construction, home appliances, clothing, footwear, dyeing and printing, fitness equipment, and ion exchange, to manufacture seals, shock absorbers, soundproofing layers, wetsuits, surfwear, beach shoes, and sports mats, among others.
