DUPLAS AP is a high quality polymer-rich APP modified bituminous torch-on membrane with a reinforcement core of spun-bond woven polyester mat, used as a capping layer in waterproofing system.
The DUPLAS range belongs to the plastoproof group of membranes produced using a special grade of bitumen modified with Virgin APP polymer. The polymer-rich mixture is used to saturate and coat both sides of the polyester mat to the required thickness of the membranes.
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.
High 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 wide range of reinforcements, thickness and surface finishes for use in variety of application.
DUPLAS AP membranes exceed the requirements of ASTM D6222, UEAtc and other relevant international standards.
