The natural aging process of asphalt is affected by three components: heat, oxygen, and UV rays. The process of oxidation uses heat and oxygen to mimic the natural aging of raw flux asphalt, raising the softening point so it can withstand the heat on a roof. Oxidation creates a more rigid shingle and is the traditional asphalt used in making shingles.
Polymer modified asphalt combines a blend of polymers with raw flux asphalt as another way to raise the softening point of the asphalt used in shingles. This process creates a more flexible shingle with superior granule adhesion and impact resistance.
ADDED FLEXIBILITY IMPROVES A SHINGLE'S RESPONSE TO STRESS.
NEX™ Polymer Modified Asphalt
Raw asphalt must be altered for use in roofing materials, but traditional methods to alter asphalt diminish its natural, rubber-like characteristics. For over 30 years, Malarkey has been engineering and manufacturing a specially formulated blend of polymers and mixing them with raw asphalt at each of our facilities to produce our resilient polymer modified asphalt.
Over the years, Malarkey has continually advanced the development of polymer modified asphalt using new technologies to refine the physical characteristics desired for quality shingle performance. NEX™, a blend of asphalt with polymers from repurposed materials, is the result. The use of polymers from repurposed materials is the next step in the ongoing effort from Malarkey to promote sustainable roofing materials while maintaining a high level of quality. This progressive approach improves asphalt flexibility, granule adhesion, cold weather installation, and impact resistance while promoting sustainable product design.
