PA-1000 Polymer Modified Mopping Asphalt
Siplast PA-1000 is an elastomeric, interply mopping asphalt designed for use with guaranteed Siplast roof systems. PA-1000 is a modified bitumen material blending heat resistant polymers with chemically matched asphalt to meet the high performance requirements for Siplast SBS-modified bitumen roof applications. The heat resistant polymeric design of PA-1000 lends demonstrably higher performance characteristics than any standard ASTM D 312 product. PA-1000 meets or exceeds ASTM D 6152 requirements.
