What This Machine Solves
Three production problems eliminated by this machine — with engineered, measurable solutions.
Standard white EPS thermal conductivity is 0.038 W/mK — premium energy-retrofit projects demand lower values for thinner insulation walls
Graphite (grey) EPS achieves 0.030-0.033 W/mK thermal conductivity — 15-20% better insulation = 15-20% thinner walls for same R-value.
Premium high-rise insulation contracts require both Class B1 fire rating + premium thermal performance — separate products are economically inefficient
Graphite-FR EPS combines both properties in one bead — single material specification simplifies project compliance.
Engineered Performance Advantages
Every advantage backed by measurable specs — no marketing claims without data.
15-20% better insulation = thinner walls = more usable floor area in building.
Includes FR additives for high-rise insulation compliance.
Premium pricing reflects premium thermal performance.
