DUSEAL PS 250 is a special SBS- modified self-adhesive protection membrane incorporating a surface reinforcement of tough, heavy-duty spun bond non–woven polyester mat. DUSEAL PS 250 is specially designed for use as protection sheet over other membrane in a wide variety of applications. The bottom surface is covered with siliconized release paper or foil. The DUSEAL range belongs to the Elastoseal group of membranes produced using a special grade of bitumen modified with virgin SBS polymer. The polymer-rich mixture is used to saturate and to coat both sides of glass fiber mat to the required thickness of the membrane.
Ease of application over existing membranes
Excellent bond to self adhesive and torch on membranes with foil finish
High tear strength and puncture resistance.
Conforms to difficult contours and shapes
High dimensional stability
Resistant to UV and to chemicals found in soil and ground water.
DUSEAL PS 250 membranes are tested to ASTM, UEAtc and other relevant international standards.
