Abstract
A lightweight dust control mat having enhanced resistance to oxidation and ozonation is provided. The mat includes a rubber backing sheet with a base rubber of NBR or SBR mixed with a polar polymer additive and a chemical blowing agent. The ratio of the base rubber to the polymer additive is between about 1.2 and 9. Following vulcanization, the rubber sheet has a specific gravity of less than about 0.98 and a Bayer ozone cracking incidence factor of 4 or less.
