Waterproofing membrane performance: 1. Water and water-resistance means that under the action of water infiltration and water after being unchanged the performance tpo waterproofing membrane, with no permeable polymer polyethylene fiber waterproofing membrane under the action of water pressure , commonly impermeability, water absorption index represents. 2. Temperature stability at high temperature stability refers not flowing, no blistering, no sliding, low temperature embrittlement of performance, that is the ability to maintain the original performance at a certain temperature. Common heat resistance, heat resistance and other indicators showing. Waterproofing membrane performance: 1, flexibility flexibility flexibility refers to maintaining performance at low temperatures. It is easy to ensure that construction does not rattle very important. 2, atmospheric stability atmospheric stability refers to the ability to resist erosion in the long term the combined effect of sunlight, heat, ozone and other chemically aggressive media and other factors. Common aging resistance, heat aging retention of other indicators showing.
