From New Jersey to the far reaches of the Northeast, including New York, Washington DC, Connecticut, Massachusetts, and beyond, our EPS solutions such as Expanded Polystyrene products serve as integral components in construction projects. Placing trust in our EPS Geofoam, a lightweight fill serving as a versatile substitute for soil, guarantees reduced load, minimized settlements, heightened stability, and enduring reliability across industrial, commercial, and residential applications.

Poly Molding Team

Leadership with Irreverence for Convention

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.

To new heights and beyond

Many clients are intrigued to discover that Poly Molding’s origins trace back to crafting mannequin heads and beer coolers. While EPS Foam still serves these functions, our operations have evolved to contribute to a diverse range of larger construction projects. Our commitment to expansion remains steadfast, aiding builders across commercial and residential sectors in constructing dependable projects of varying kinds that stand resilient and enduring over time.

In a pivotal move, Adam and his father recognized the need for ownership continuity to uphold Poly Molding’s flourishing trajectory. In 2011, he took the reins entirely, solidifying his commitment. With years of tenacious experience under his belt, Adam has driven Poly Molding’s ascent, propelling it to the forefront as a premier EPS manufacturer.
