*PolySeal
Polymer Modified Bitumen Binder for Spray Sealing Applications
This binder is a composite product manufactured from blends of bitumen, polyethylene and elastomeric polymers. PolySeal is a PMB which derives unique properties resulting in performance benefits contributed by each polymeric additive. In addition to the "toughness" imparted by the polyethylene, the elastomers increase the binders elasticity and promotes superior adhesion with the aggregate. The combination of great toughness and excellent adhesion make the polyethylene composite PolySeal, a superior sealing binder which does not significantly compromise intrinsic elastic properties or temperature susceptibility.
Features and benefits
