(Polymer Modified Asphalt Roofing)

EFG SBE-PMAR (Styrene Butadiene Elastomer-Modified Asphalt Roofing) is a high quality engineered elastomer designed to mitigate the most challenging problems in polymer modified asphalt roofing applications.

EFG engineered elastomers are manufactured from post consumer and post industrial waste rubber. EFG certifies at least 85% reactivated content. EFG SBE-PMAR builds on the styrene butadiene backbone for elastomeric modification while also delivering the benefits of reinforcing carbon black, antioxidants and antiozonants.

Customers have established that up to 100% of SBS or SEBS can be replaced with EFG SBE-PMAR dramatically improving thermomechanical stability, UV protection, viscosity stabilization and delivering profitability and sustainability.
