DynaLastic 180 S is used as a polyester-reinforced base or ply sheet in a variety of multi-ply roofing systems.
High-Quality SBS Rubber and Asphalt Blend: Lends elasticity and flexibility to the sheet. The elongation and recovery properties allow the product to easily accommodate the continual expansion and contraction experienced on all roofs.
Polyester Reinforcement Mat: Polyester mat with bidirectional glass-scrim reinforcement offers robust tear strength and puncture resistance, allowing for high wind performance and an excellent hail rating. The sheet also exhibits strong dimensional stability and enhanced elongation.
Surfacing: A fine material parting agent is applied to both sides of the product.
