BUR

(Built Up Roofing)

EFG Elastomers can replace up to 100% of virgin polymers in BUR applications. Where EFG SBE-PMAR is used in combination with virgin polymers, EFG elastomer stabilizes thermomechanical properties of SEBS and SBS, while enhancing UV protection and viscosity stabilization.

​EFG SBE-PMAR is designed to improve the roofing product performance and longevity, while improving profitability and sustainability.
