Polystyrene foam board, often referred to as EPS board or simply foam board, serves as an indispensable protective layer for waterproofing applications. Crafted meticulously from expandable polystyrene beads, each containing a unique volatile liquid foaming agent, this foam is transformed through a pre-expansion heating process into a pristine white solid featuring a sophisticated, fine closed-cell structure.
SOHO presents its premier line of polystyrene insulation boards, featuring both standard and graphite-enhanced variations. These insulation marvels are crafted using cutting-edge equipment imported from South Korea, combined with state-of-the-art European technology and premium imported raw materials. Notably free from chlorofluorocarbons or hydrochlorofluorocarbons, these boards are designed to not only prolong the insulation life of buildings but also significantly diminish CO2 emissions, offering an eco-friendly solution without compromising on performance.
Main Applications: Our EPS SIP panel and EPS sandwich panel stand as the ideal solution for building wall and roof insulation, as well as serving as the insulation layer in composite insulation boards. Additionally, they are utilized as insulation materials for a diverse range of applications including vehicles, ships, refrigeration systems, and cold storage facilities. Beyond functional applications, they also offer creative versatility for decorating and sculpting a variety of models.
