Yuzhimu Nonwoven Fabric-Carrier For Bitumen Membranes

Yuzhimu non-woven fabric is used as a carrier in bituminous membranes. The high tear strength of this non-woven fabric contributes to the dimensional stability of the bituminous membrane while providing elasticity, making the roof sturdy. It is also mentioned that by adjusting the weight, diameter, stretch rate, and density, the breathability and puncture resistance of non-woven fabrics can be customized to meet different application requirements. The main function of Yuzhimu non-woven fabric in bituminous membrane is to enhance structural strength, provide dimensional stability, improve asphalt adhesion, increase flexibility and durability.

Yuzhimu non-woven fabric mainly plays the following key roles in bituminous membrane：

Structural reinforcement and support：
As a supporting material for bituminous membranes, yuzhimu non-woven fabric provides mechanical support through its high-strength fibers, enhancing the tensile strength and puncture resistance of bituminous membranes while maintaining dimensional stability and preventing deformation caused by temperature changes or structural displacement.

Improve the adhesion and distribution of bituminous membranes：
The porous structure of non-woven fabric can fully absorb and evenly distribute asphalt, forming a stable composite layer and enhancing the overall integrity and waterproof performance of bituminous membranes. Its fiber properties can also enhance the adhesion between bituminous membranes and substrates, reducing the risk of delamination.

Enhance flexibility and durability：
The elastic properties of non-woven fabric enable asphalt film to have better ductility, adapt to slight displacement of the base layer, and delay the occurrence of cracks. At the same time, its chemical resistance and anti-aging properties help to extend the service life of bilateral membranes.

Environmental Protection and Economy：
Non woven fabric material is recyclable (PET), and lightweight design reduces waste and overall structural weight, in line with sustainable building trends.
