High density cellular foams do not absorb water for the first 5-7 years (until UV breaks down the foam and they become absorbent), so any water that enters the roof through a breach in the membrane goes straight into the building. This is not a good consequence, since keeping the water out of the building is the purpose of waterproofing.2013 Technical Abstracts - SPIE - MAFIADOC.COMHigh density cellular foams do not absorb water for the first 5-7 years (until UV breaks down the foam and they become absorbent), so any water that enters the roof through a breach in the membrane goes straight into the building. This is not a good consequence, since keeping the water out of the building is the purpose of waterproofing.5 Lightweight Protective Materials Ceramics, PolymersWhile B 4 C and SiC ceramics require temperatures of 2150°C to 2200°C and, typically, applied pressure to carry out sintering to achieve to full density, alumina can be easily sintered into complex shapes to full density at 1500°C to 1600°C by pressureless sintering.
