DynaWeld 250 S

Product Long Description

Features

DynaWeld 250 S

Features

Meets the requirements of ASTM D 6164, Type II, Grade S

Fine Mineral Parting Agent: Nonblocking surface for use as a base sheet or ply sheet.

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.

Heavy Duty Polyester-Reinforcement Mat: Provides excellent tensile strength, toughness and puncture resistance, and it can accommodate stresses created by typical rooftop expansion and contraction forces.

Polyolefin Burn-Off Film: Promotes ease of heat welding.
