The main classifications of waterproof membranes are: SBS waterproof membrane, polypropylene waterproof membrane, EPDM waterproof membrane, PVC waterproof membrane, app waterproof membrane, TPO waterproof membrane.

1. Features of SBS waterproof membrane:
SBS modified asphalt waterproof coiled material is made of SBS rubber modified petroleum asphalt as an intrusive covering layer, made of polyester fiber nonwoven fabric, jute cloth, glass fiber felt, etc. as the tire base, and plastic film as anti-sticking isolation The layer is processed through the processes of material selection, ingredients, eutectic, infiltration, composite molding, and curling.

Performance characteristics: low temperature flexibility, no cracks at -25 ℃; high heat resistance, no flow at 90 ℃. Good elongation performance, long service life, easy construction and low pollution. The product is suitable for the waterproof engineering of Grade I and II buildings, especially for the waterproof engineering of buildings with low temperature and cold areas and frequent structural deformation.

Specification classification: According to physical indicators, it is divided into two categories: Ⅰ (-20 ℃) ​​and Ⅱ (-25 ℃);
According to the tire base, it can be divided into two categories: polyester tire and glass fiber tire; according to the cladding material, it can be divided into four categories: PE film (aluminum film), colored sand, shale sheet, fine sand, etc .; width: 1000mm, with lengths of 10m and 15m; thickness: polyester felt rolls 3Mm, 4mm, 5mm; glass fiber felt rolls 3Mm, 4mm; glass fiber reinforced polyester felt rolls 5mm.
Scope of application: Widely used in waterproofing and dampproofing of roofing, basement, toilets and other waterproofing projects in industrial and civil buildings and roof gardens, roads, bridges, tunnels, parking lots, swimming pools and other projects. For projects with large deformation, polyester tire products with excellent elongation properties are recommended, and other buildings should use relatively economical glass fiber tire products.

2. Features of polypropylene waterproof membrane:
1. Fully adhesive construction of polypropylene waterproof membrane can effectively avoid aging under the effect of protective layer, no drum, no horizontal channeling.
2. The polypropylene waterproof membrane and the base layer form an integral waterproof structure
3. The polypropylene waterproof membrane can be constructed in rainy days to ensure the progress of the project
4. Cement bonding is unique. The most prominent feature of polypropylene waterproof membrane is its rough and uniform surface, easy to bond, suitable for bonding with a variety of materials, can be directly bonded with cement materials during the setting process, and peeled off. The strength is 15N / cm, which is a performance that other waterproof materials do not have. Polypropylene waterproof coiled material can be stably attached to the vertical position, can be stably attached to the horizontal surface, and can be decorated on the outer surface (such as cement mortar plastering, pasting tiles or mosaics, etc.).
5. The waterproof of the full protection system realizes the longest waterproof life and achieves a good combination with the base of the building, so that the polypropylene waterproof membrane and the base are integrated.
6. Supporting node profiles, to prevent node leakage, key protection of node parts.
7. The product is thin and has poor puncture resistance, small elasticity and poor adaptability of the base layer (relative to the coating film), and the heat resistance is slightly poor (relative to the rigid waterproof).

3. Features of EPDM waterproof membrane:
EPDM waterproof membrane is a kind of polymer waterproof membrane. It is mainly composed of EPDM rubber, mixed with appropriate chemical additives and a certain amount of filling materials, after batching, mixing, mixing, and worrying. , Extrusion molding, vulcanization, inspection, sub-rolling, packaging and other processes made of high elastic rubber waterproof membrane.
1: High tensile strength: The tensile strength of EPDM waterproof membrane is high, which can meet the practical requirements of construction and application;
2: High elongation at break: The elongation at break of the EPDM waterproof membrane can be well adapted to the needs of expansion or cracking of the waterproof base of the construction project to ensure the waterproof quality;
3: Good resistance to high and low temperature, low temperature can reach -40 ℃, high temperature can reach 160 ℃, can be used in harsh environments for a long time. Therefore, the use of EPDM waterproof membrane in low temperature conditions can improve the durability of the waterproof layer and enhance the adaptability of the waterproof layer;
4: Strong corrosion resistance: The EPDM rubber waterproof membrane has strong ozone resistance, ultraviolet resistance, weather resistance and other capabilities, good aging resistance, and extended waterproof durability;
5: High construction technology requirements: need skilled workers to operate. It is difficult to completely bond with the base layer; there are many lap joints, which are easy to cause leakage problems due to poor joint bonding. Therefore, it should be combined with paint to enhance the integrity of the waterproof layer and improve the reliability of waterproofing.
6: Wide range of application: suitable for waterproof construction of building roofs and basements.

Fourth, the characteristics of PVC waterproof membrane:
1. High tensile strength, good elongation, and small change rate of thermal dimension.
2. It has good weldability, and the seam is integrated with the base material after hot air welding.
3. It has good water vapor diffusivity, the condensate is easy to be released, and the moisture and moisture left at the base are easy to be discharged.
4. It has good resistance to aging, ultraviolet radiation, chemical corrosion and root penetration.
5. It has good flexibility at low temperature (-20 ℃).
6. Long service life (25 years on the roof and 50 years on the ground), and no environmental pollution.
7. The surface of the color reflects ultraviolet radiation, the surface of the PVC waterproof membrane absorbs less heat, and the temperature is low.
8. Excellent flexibility and stretchability, high tensile strength, good dimensional stability, high mechanical strength, erosion resistance, root penetration resistance, weather resistance and UV resistance, and hail resistance.

5. Features of app waterproof membrane:
1. Strong impermeability
2. High tensile strength, large elongation, good dimensional stability, good adaptability to shrinkage and cracking of the base layer
3. Good resistance to high and low temperature, SBS is suitable for building waterproofing in lower temperature environment, APP is suitable for building waterproofing in higher temperature environment
4. Puncture resistance, puncture resistance, tear resistance, corrosion resistance, mildew resistance, good weather resistance

6. Features of TPO waterproof membrane:
1. High elasticity, high strength and high elongation;
2. Long-term weather resistance, aging resistance, low density;
3. Effectively resist the erosion of harmful chemical substances and industrial pollutants, wear and puncture resistance;
4. Anti-ultraviolet, in line with energy saving and environmental protection;
5. The joint is formed by welding thermoplastic, which is firm and reliable, and has long-term weldability;
6. Stable size and color, good plasticity, suitable for detailed treatment;
7. The wet base surface can be constructed, no protective layer is exposed, and the construction is convenient and pollution-free.
