DULAS AP is a high quality polymer-rich SBS modified bituminous torch-on membrane with a reinforcement core of spun-bound non-woven polyester mat, used as a capping layer in waterproofing system.
The DULAS range belongs to the Elastoproof group of membranes produced using a special grade of bitumen modified with virgin SBS polymer. The polymer-rich mixture is used to saturate and coat both sides of the polyester mat to the required thickness of the membranes. The top surface of the membrane is laminated with a high quality aluminum foil, which protects the membrane from weathering, UV rays and the bottom surface covered by torchable polyethylene foil.
FEATURES AND BENEFITS
High mechanical properties: good movement accommodation; resistant to tear and puncture
High resistance to hydraulic pressure: provides an impermeable and low absorption layer.
Wide temperature tolerance: stable in tropical climates; resistant to thermal ageing and shock.
High chemical resistance: withstands effects of salts and other corrosive agents in soil and water.
Versatile: available with a range of reinforcements, thickness and surface finishes for use in variety of applications.
DULAS AP membranes are tested in accordance with UEAtc(European union for technical agreement for construction industry) and can be tested as per ASTM D5147 (Standard Test Method), ASTM D6164 (Standard Specification) and other relevant international standards.
