루핑 멤브레인, 조성물, 및 그의 제조 방법
루핑 멤브레인 및 그의 제조 방법이 제공된다. 루핑 멤브레인은 난연제 및 0.90 g/cm미만의 밀도를 갖는 제1 실란-가교된 폴리올레핀 엘라스토머를 갖는 상단 층; 스크림 층; 및 난연제 및 0.90 g/cm미만의 밀도를 갖는 제2 실란-가교된 폴리올레핀 엘라스토머를 갖는 저부 층을 포함한다. 루핑 멤브레인의 상단 및 저부 층은 둘 다, ASTM D 395 (70℃에서 22시간)에 따라 측정시, 약 5.0 % 내지 약 35.0 %의 압축 영구변형률을 나타낸다.
A roofing membrane and a method of making the same is provided. The roofing membrane includes a top layer having a flame retardant and a first silane-crosslinked polyolefin elastomer with a density less than 0.90 g/cm3; a scrim layer; and a bottom layer having a flame retardant and a second silane-crosslinked polyolefin elastomer with a density less than 0.90 g/cm3. The top and bottom layers of the roofing membrane both exhibit a compression set of from about 5.0% to about 35.0%, as measured according to ASTM D 395 (22 hrs @ 70° C.).
