Weifang Zhengtai Waterproof Material Co., Ltd. was established in 2001 year with the registered capital of 1 billion , covering area of 60000 square meter .
The upper surface protections of APP (Atactic Polypropylene) modified bitumen membranes actively improve functionality and extend lifespan.Here are the key surface protection types actively used for APP membranes:
– The membrane surface incorporates mineral granules, which actively enhance durability and aesthetic appeal, available in a range of colors.
– Benefits: Offers protection against UV rays, enhances visual appeal, and increases resistance to mechanical wear and environmental conditions.
–An aluminum foil layer is bonded to the membrane’s surface, actively reflecting UV rays and heat to improve energy efficiency and protect against degradation
– Benefits: Provides superior UV and heat reflectivity, minimizing heat absorption and extending the membrane’s lifespan.
3. Sand or Fine Mineral Particles:
–The membrane surface is coated with sand or fine mineral particles, actively enhancing slip resistance and providing additional protection against wear and UV damage.
–The benefits include, first, preventing the membrane from adhering during storage and handling. Moreover, it creates a non-slip surface, enhancing safety during installation.
–A thin layer of polyethylene film is applied to the membrane’s surface, actively providing a barrier against moisture, chemicals, and physical damage
–The benefits of this include, firstly, simplifying the unrolling process during installation. Additionally, it prevents self-adhesion of the membrane, ensuring smoother handling.
–A non-woven fabric layer is bonded to the membrane, actively reinforcing protection, boosting durability, and shielding against mechanical damage.
– Benefits: Improves walkability, provides extra mechanical protection, and serves as a foundation for subsequent coatings or surfacing materials.
–Reflective coatings or paints actively reflect sunlight, cut down heat absorption, boost energy efficiency, and protect the membrane from UV degradation.
– Benefits: Enhances UV resistance, decreases heat absorption, and prolongs the membrane’s durability.
