"Styrofoam" is made up of 98% air, making it highly resource-efficient. The raw material ratio is only 2% of the total. When burned, it does not produce dioxins, and if completely combusted, it turns into carbon dioxide (CO2) and water (H2O). Incomplete combustion produces black smoke, which is soot. No fluorocarbons are used at all, and the foaming gases used are butane and pentane. In 2010, we achieved a recycling rate of 88.0% for collected materials, demonstrating excellent recycling characteristics. [Features] ■ 98% air, making it highly resource-efficient ■ Does not produce dioxins when burned ■ No fluorocarbons used ■ Excellent recycling characteristics *For more details, please refer to the PDF document or feel free to contact us.

"Styrofoam" supports society in various ways and is something that is very close to us and indispensable. In agriculture and fisheries, its high thermal insulation and cooling properties help maintain the freshness of agricultural and marine products, supporting the industry. Its excellent cushioning protects fragile items and precision equipment from external impacts. Additionally, being a lightweight material, it also enhances transport efficiency, supporting logistics. Furthermore, it is used as insulation in residential walls, improving heating and cooling efficiency, thus supporting construction. [Features] - Supports agriculture and fisheries - Supports logistics - Supports construction *For more details, please refer to the PDF document or feel free to contact us.

"Styrofoam" is a foam material made by expanding small beads of polystyrene (PS), which is derived from petroleum, to about 50 times their original size, with the beads having a diameter of approximately 1mm. It consists of 98% air by volume. As a result, it has excellent characteristics that other materials do not possess. Being a single material, it is easy to sort and collect, making it not only highly recyclable but also versatile in terms of shape, hardness, and weight, which enhances its moldability. [Features] - Excellent thermal insulation and cooling properties - Resistant to water and moisture (this does not necessarily mean it does not absorb water) - Moderate cushioning and strength *For more details, please refer to the PDF document or feel free to contact us.
