Asphalt compound made more water resistant and durable with the addition of polymers. Applied as a water resistant coating for types of roofing or as a preservative coating on wood.

a bitumen modified by one or more polymers, such as Atactic Polypropylene (APP) or Styrene Butadiene Styrene (SBS).

Bitumen modified by special processing, generally with the addition of SBS type rubber or atactic polypylenes (APP). Some are non-reinforced, while others are reinforced with polyester, polyvinyl acetate, fiberglass, polypropylene or aluminum foil.

Rolled roofing membrane with polymer modified asphalt and either polyester or fiberglass reinforcement.

A material consisting of asphalt which has been modified through the inclusion of one or more polymers and may contain stabilizers and other additives. Modified bitumen roofing membranes may also contain a reinforcing material.

a modified bitumen membrane roof system is typically composed of factory-fabricated composite sheet consisting of a copolymer modified bitumen which is typically reinforced and installed in one or more plies. The modified sheets are typically fully - adhered by heat welding (torching).

Prefabricated bitumen roofing membranes modified by elastomeric or polymeric compounds.

A bitumen modified by including one or more polymers (e.g., atactic polypropylene, styrene butadiene styrene, etc.). Also, composite sheets consisting of a polymer modified bitumen often reinforced with various types of mats or films and sometimes surfaced with films, foils or mineral granules.
