The characteristics of waterproof polypropylene non-woven fabrics, why thin waterproof polypropylene non-woven fabrics can be waterproof, I believe that my friends have a lot of questions, the following editor tells you the reasons, first look at the characteristics of waterproof polypropylene:

1. Three-layer(SMS Polypropylene Fabric Factory) structure with enhanced surface

2. The core layer-the main waterproof layer uses linear low-density polyethylene (LLDPE) with a higher branch ratio (more macromolecular side chains), which has extensibility, impermeability, flexibility, puncture resistance, and low temperature resistance Performance is better.

3. The surface is made of polypropylene non-woven fabric, which solves the problem of large linear expansion coefficient of polyethylene by compounding with the core layer. The surface roughness of the product is increased, the friction coefficient of the product is improved, and the bonding problem of the composite coil is solved, and cement bonding is realized.

Structural characteristics of waterproof polypropylene non-woven fabric(Nonwoven SMS Wholesale):

It has strong impermeability, high tensile strength, good low temperature flexibility, low linear expansion coefficient, easy bonding, large friction coefficient, good stability, non-toxic, strong deformation adaptability, wide temperature range, long service life, etc. The comprehensive technical performance. Polyethylene and polypropylene (polypropylene) are chemically stable, resistant to corrosion, mildew, and ozone, while polypropylene has good mechanical properties.

Features of waterproof polypropylene non-woven fabric(Medical SMMS Material Manufacturer):

1. Polymer waterproofing membrane belongs to the series of synthetic polymer waterproofing membranes. In addition to fully having all the advantages of synthetic polymer membranes, its own outstanding feature lies in the network structure on its surface, which gives it its own Unique performance-cement bonding.

2. Because the polymer composite coil can be directly bonded with cement, it will not be affected by the moisture content of the base layer during the construction process. It can be constructed as long as there is no clear water. This is not available in other waterproof membranes.

3. Due to the rough surface of the polymer composite coil and the large friction coefficient, it can be directly buried in sand and has sufficient stability when used in water conservancy projects.

4. Since the polymer composite coil can be directly bonded to the cement material during the solidification process, it can be directly designed in the structure of the cement material.
