R-EPS
Sustainable Recycled Expandable Polystyrene — High Performance from Recycled Materials
High-Performance EPS from Recycled Materials
Our R-EPS is an eco-friendly polymer material produced from recycled polystyrene foam and other waste materials via our advanced extrusion EPS process. Designed with circular-economy principles, R-EPS delivers the same mechanical properties and durability as virgin EPS while significantly reducing environmental impact.

How We Make It
Our R-EPS is engineered using an advanced process that transforms post-consumer and industrial polystyrene waste into premium-quality EPS beads.
Recycled Content
Supports 10–100 % recycled polystyrene (PS) content, efficiently reprocessing post-consumer and industrial waste.
Optimised Foaming Formula
Produces fine, uniformly distributed cells with intact walls, delivering excellent strength and thermal insulation.
Supercritical Mixing
Homogeneous blending of blowing agents and PS under supercritical conditions ensures consistently superior quality.
Continuous Pelletising
High-pressure pelletising process yields uniform EPS beads without pre-expansion, enhancing efficiency and consistency.
Benefits
