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.

SPECIAL FEATURES
