Styrene-Butadiene Copolymer Description: Finaprene® 409 is a thermoplastic elastomer type radial styrene-butadiene block copolymer (SBS). Because of its high molecular weight, Finaprene® 409 provides excellent mechanical and elastic properties to the roofing sheet. Applications: Thanks to its high molecular weight Finaprene® 409 is designed for the roofing industry. Its high styrene content, along with the high molecular weight confer an excellent temperature range at a fairly low viscosity and an easy dispersion to the modified bitumen. Additional Notes: Oil Content: 5 phr; Finaprene 1010 Data provided provided by Total Petrochemicals. Total Petrochemicals includes former Fina and Atofina plastics product lines. |
