Honeycomb rubber is a porous structural material with holes throughout the entire material, featuring low density, good elasticity, and high flexibility. It also provides shock absorption, noise insulation, and heat insulation properties. Its hole structures can be classified 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 made into soft or hard rubber products. They are produced 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. It is utilized to manufacture seals, shock absorbers, noise barriers, wetsuits, surf suits, beach shoes, and sports mats, among other products.
