Building material processing: Expanded Polystyrene (EPS, prototype, modeling, decoration)

Building structures with expanded polystyrene... An idea no one had thought of has been realized through human wisdom and technology.

Decoform utilizes the characteristics of lightweight and elastic expanded polystyrene while also providing strength and resistance to aging, allowing for virtually limitless freedom in design and molding. It is already being used in a wide range of applications, from general architecture to commercial facilities such as hotels and restaurants, office buildings, and theme parks, including everything from small items to interior and exterior materials for buildings, three-dimensional sculptures, and signs. It is not an exaggeration to say that architectural design and industrial design have gained new freedom through Decoform; we are confident in this belief.

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.
