Modified-Grade EPS for Fire-Retardant Applications
The same trusted EPS performance, formulated to meet flame-retardant (FR) requirements.
Epsilyte’s Modified-Grade EPS offers the same reliable performance as our standard EPS, with the added benefit of FR capability. This grade is used when building codes, safety standards, or end-use requirements specify materials that include fire retardant.
What is Modified-Grade EPS?
Modified-Grade EPS is expanded polystyrene that includes a flame-retardant (FR). Outside of FR content, it performs the same as standard EPS. The material maintains the familiar light weight, moldability, thermal performance, and strength characteristics that make Epsilyte’s EPS one of the most versatile materials in the world.
