PO防水卷材綜合了EPDM和PVC的性能優(yōu)點(diǎn),具有前者的耐候能力、低溫柔度和后者的可焊接特性。這種材料與傳統(tǒng)的塑料不同,在常溫顯示出橡膠高彈性,在高溫下又能像塑料一樣成型。因此,這種材料具有良好的加工性能和力學(xué)性能,并且具有高強(qiáng)焊接性能。而在兩層TPO材料中間加設(shè)一層聚酯纖維織物后,可增強(qiáng)其物理性能、提高其斷裂強(qiáng)度、抗疲勞、抗穿刺能力。
在實(shí)際應(yīng)用中,該產(chǎn)品具有抗老化、拉伸強(qiáng)度高,伸長(zhǎng)率大、潮濕屋面可施工、外露無須保護(hù)層、施工方便、無污染等綜合特點(diǎn),十分適用于作為輕型節(jié)能屋面的防水層。
