Basic Knowledge of Styrofoam

Basic Knowledge of Styrofoam

Versatile for various uses! Utilizing its cushioning properties, it protects important items from shocks and gently wraps them.

Expanded polystyrene is a material that also shuts out heat and moisture, taking the environment into consideration. Utilizing its cushioning property, it effectively protects precision instruments, home appliances, and delicate fruits, safeguarding valuable items from impact and gently enveloping them. With functions that block heat and moisture, it is widely used in the fields of construction and civil engineering as insulation and moisture-proof materials for floors, walls, and ceilings. Since 98% of its composition is air, it is very lightweight and has significant buoyancy, which is one of its advantages. Additionally, it excels in water resistance, making it effective in various work environments that handle water. 【Features】 ■ Packaging and protection ■ Blocks heat and moisture ■ Lightweight and water-resistant ■ Easy to process ■ Environmentally friendly *For more details, please refer to the external link page or feel free to contact us.

Properties of Styrofoam

Properties of Styrofoam

Because it is made of a single material, it is easy to sort and collect, making it highly recyclable.

"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 being approximately 1mm in diameter. It consists of 98% air by volume. As a result, it has excellent characteristics that are not found in other materials. 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 contributes to its excellent moldability. 【Features】 ■ Outstanding thermal insulation and cooling properties ■ Resistant to water and moisture (Note: 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.

Environmentally friendly expanded polystyrene

Environmentally friendly expanded polystyrene

98% air! It is resource-efficient and does not produce dioxins when burned!

"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 butane and pentane are used as the blowing agents. By 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.
