Please try "Miyahara's sponge," known for high quality, a wide variety, and small lot production.
◆High Quality - Uniformity: When processing companies cut thickness, they compress the material slightly, which can result in sponges that lack uniformity due to varying hardness in certain areas. Even if cut evenly, when the material returns to its original state, the thickness will not be uniform, rendering it defective as a material. Based on our cultivated manufacturing technology, we can produce rubber sponges with uniformity by meticulously working on each piece, something that large competitors in the same industry do not offer. - Adhesiveness: Rubber sponge materials that have undergone adhesive processing by processing companies may lose their adhesive strength and become unusable after about three months. It is said that gases emitted from the rubber sponge can compromise the adhesive, but by adjusting the formulation according to the material, we can create rubber sponges that suppress gas generation and do not compromise the adhesive. ◆Variety of Products We have over 100 self-developed products based on natural rubber and various synthetic rubbers such as CR, EPDM, NBR, and NR/SBR. ◆Small Lot Production For stock items, you can purchase from a single sheet of raw material.

basic information
Rubber sponge is a material made using a highly specialized method that chemically synthesizes rubber raw materials with inorganic and organic rubber chemicals simultaneously during foaming. The manufacturing of rubber sponge varies depending on the type of rubber raw materials, leading to differences in formulation and processes. Additionally, due to seasonal variations in temperature and humidity, precise adjustments are necessary not only for the chemical formulation but also for kneading time, baking time, and other subtle factors. This adjustment affects the quality, making it a complex material. However, due to its excellent elasticity and heat resistance, which are not found in resin sponge, it has been used for a long time as a material for parts requiring high functionality such as soundproofing, waterproofing, dustproofing, and vibration damping. In the future, for components requiring lightweight materials in vehicles and aircraft, high-foaming sponges will be utilized, while environmentally friendly materials such as sulfur-free and low-VOC sponges will be used in low-voltage products. For sports-related products, sponges with unique rebound elasticity will also be manufactured, contributing to the production of high-value-added products.
