Honeycomb rubber is a porous material with holes throughout its entire structure, characterized by its low density, good elasticity, and strong flexural strength, and it also offers shock absorption, noise insulation, and heat insulation properties. Its pore structures 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 made through a vulcanization process with the addition of 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, surfwear, beach shoes, and sports mats.
