Low Temperature Flexible Crack-proof App Modified Asphalt Membrane
Product Advantages
1. Excellent high temperature resistance: Adopting APP atactic polypropylene modified formula, the membrane features outstanding thermal stability. It keeps no flowing or slipping at 130℃, suitable for high-temperature and strong sunlight exposure environments such as southern regions and exposed roofs, effectively avoiding water leakage risks under high temperature.
2. Superior weathering and aging resistance: It has excellent resistance to UV radiation, ozone and climatic aging. It is not easy to powder, crack or peel off during long-term outdoor service, greatly extending the service life of the waterproof layer and reducing later maintenance costs.
3. Excellent mechanical properties: The polyester-reinforced membrane owns high tensile strength, tear resistance and puncture resistance with high elongation rate. It can effectively adapt to slight settlement, expansion and cracking deformation of building substrates and prevent failure of the waterproof layer.
4. Outstanding corrosion resistance: Resistant to acid, alkali, salt spray, groundwater and various industrial medium corrosion. It maintains stable long-term performance in humid and corrosive working conditions such as basements, tunnels and industrial workshops.
5. Good dimensional stability: It has extremely low deformation rate under alternating cold and hot temperatures, avoiding blistering, edge warping and cracking caused by temperature changes, ensuring high flatness and tight sealing of the waterproof layer.
6. Wide construction adaptability: Adopting mature hot-melt construction technology with firm bonding and excellent sealing performance. It is applicable to new and reconstruction projects as well as low and high temperature construction environments.
7. Diverse optional specifications: Three surface types are available: PE film finish, fine sand finish and aluminum foil finish. The sand surface can be used as a direct protective layer, while the aluminum foil surface reflects sunlight and reduces roof temperature, meeting both exposed and non-exposed waterproofing requirements.
8. High cost performance: Glass fiber reinforced membrane features stable dimension and cost effectiveness; polyester reinforced membrane has strong toughness and deformation resistance. Double substrate options cater to different project budgets and working conditions.
9. Environmentally friendly and non-toxic: No harmful additives are used in production, no VOC volatilization during construction. It is eco-friendly and complies with national environmental acceptance standards for residential and public buildings.
10. Reliable waterproof sealing performance: The membrane features dense and uniform material structure. The hot-melt overlapping joints form an integral seamless structure with strong water pressure resistance, effectively blocking permeating water and ensuring long-lasting waterproof effect.
