FIELD: chemistry.
SUBSTANCE: roofing membrane contains 2 layers. The first layer comprises from approx. 20 to approx. 50 wt % of vulcanized EPDM rubber, from approx. 70 to approx. 100 wt parts of carbon black, from approx. 78 to approx. 103 wt parts of clay, from approx. 55 to approx. 95 wt parts of expander and at least 2 wt parts of thermally expanding graphite, with all wt parts designed per 100 wt parts of vulcanized EPDM rubber. The second layer comprises vulcanized EPDM rubber and is substantially free of thermally expanding graphite.
EFFECT: invention allows to improve the roofing membrane quality and increase its resistance to combustion.
