Our team is headed by Adam Corn. Adam invested three years of hard work in mastering Poly Molding LLC equipment and machinery after college. He launched the company’s sales department in the
mid-90s and spent the next decade and a half building an expansive customer base. Poly Molding’s gradual progression throughout the entire northeast region is the direct result of Adam’s hard work.
Many clients are surprised to learn that Poly Molding began by producing mannequin heads and beer coolers. While EPS foam still plays a role in those applications, our operations have since evolved to support a wide variety of large-scale construction projects. Today, we remain committed to growth—partnering with builders across the commercial and residential sectors to deliver dependable, high-performance solutions. From lightweight fill to thermal insulation, our EPS products help create structures that are resilient, efficient, and built to last.
Adam is the owner and driving force behind Poly Molding, a leading Expanded Polystyrene (EPS) foam manufacturer. Immersed in the family business from the age of thirteen, Adam developed hands-on expertise in EPS foam production, warehousing, and manufacturing operations. After earning a management degree in 1992, he joined the company full time, building a dedicated sales team and advancing product development. In 2011, Adam assumed full ownership, ensuring continuity and long-term growth. Under his leadership, Poly Molding has emerged as a top-tier provider of high-performance EPS foam insulation and custom-molded polystyrene solutions for construction and industrial applications.
Our timely service and excellent customer relations are the reason why Poly Molding supplies most major distributors and has made us the leader in the Expanded Polystyrene (EPS) Geofoam industry. Our factory is conveniently located in Northern New Jersey and we service clients through the East coast of the US.
