High-Polymer Modified Bitumen Waterproofing Coil Membrane
High-Polymer Modified Bitumen Waterproofing Coil Membrane
Product Overview
 High-Polymer Modified Bitumen Waterproofing Membrane is a rollable sheet waterproof material made with synthetic polymer modified bitumen as the coating layer, fiber fabric or felt as the carrier, and powder, granule, sheet, or film materials as the facing layer. It combines the characteristics of traditional bitumen waterproof membranes and polymer waterproof membranes, overcoming the disadvantages of poor temperature stability and low elongation of conventional bitumen membranes. This high-performance waterproof material is widely used in waterproofing projects for industrial and civil buildings, including roofs, basements, and bathrooms, as well as in civil engineering applications such as bridges, roads, and tunnels for waterproofing and moisture-proofing.


Polymer Modified Bitumen Waterproof Membrane Specifications:
Membrane Thickness: 4.5mm
Width: 1m, 2m, 2.2m
Length: 10m
Other specifications to be agreed upon by both parties.

Product Feature
Good Weather Resistance: Through polymer modification, the membrane exhibits better high and low-temperature performance, maintaining stable properties across a wide temperature range. It does not flow or stick at high temperatures and does not become brittle at low temperatures, making it suitable for various climatic conditions.

High Tensile Strength: Compared to ordinary bitumen waterproof membranes, its tensile strength is significantly increased, allowing it to withstand substantial pulling and deformation without tearing. It maintains the integrity of the waterproof layer even when the substrate undergoes some deformation.

High Elongation Rate: With a high elongation rate, it can accommodate the expansion and contraction of the substrate and prevent damage to the waterproof layer caused by substrate deformation, enhancing the reliability and durability of the waterproofing project.

Strong Tear Resistance: The membrane has a high tear strength, enabling it to resist damage from external factors such as sharp objects and mechanical damage during construction, thereby reducing the likelihood of damage to the waterproof layer.

Easy to Install: It can be applied using various methods, including hot melt and cold adhesive techniques, making the operation simple and construction fast. Particularly, the hot melt method does not require adhesives; instead, it uses heat to melt the adhesive at the bottom of the membrane, ensuring a strong bond with the substrate and minimizing the risk of hollow spots.

Excellent Waterproof Performance: The addition of polymers enhances the waterproofing properties of the bitumen, resulting in improved waterproofing effectiveness that effectively prevents moisture penetration, providing reliable waterproof protection for projects.
