Flexible Styrofoam/Styrofoam 25mm

Lightweight: Because the material is composed of over 95% air, it is extremely lightweight, making it ideal for packaging and insulation where weight is a factor. ​Excellent Thermal Insulation: The trapped air pockets in the foam's structure make it a highly effective insulator. It resists heat transfer, which is why it's widely used in building insulation, coolers, and disposable hot beverage cups.
