Product Specifications

Product Structure

Front and back: both are 30-micron-thick white flame-retardant polypropylene, providing excellent flame retardancy and a degree of physical protection.
Adhesive: A flame-retardant bonding adhesive is used, which not only securely bonds the layers together but also further enhances the product’s flame-retardant properties.
Reinforcing ribs: A three-directional glass fiber mesh is employed, with a longitudinal specification of 20/100 mm and an oblique specification of 16/100 mm, which enhances the product’s tensile strength and tear resistance, thereby improving overall structural stability.

Physical Properties

Weight: The weight is 65 grams per square meter, making it relatively lightweight and easy to install and handle.
Water vapor transmission rate: only 5.5 ng/N·s (tested according to ASTM E96 Procedure A), demonstrating excellent moisture-barrier performance and effectively preventing water vapor penetration.
Puncture resistance: ≥350 N (tested in accordance with Appendix A of JC/T 2028-2018), demonstrating excellent resistance to external puncture and compressive forces.
Tensile strength: the longitudinal tensile strength is 7.8 kN/m, and the transverse tensile strength is 7.6 kN/m (as determined by ASTM C1136 testing), demonstrating that the product exhibits excellent tensile performance in both directions.
Thickness: 0.16 mm, making it a relatively thin yet high-strength material.
Fire resistance rating: Meets the B1 grade specified in GB 8624-2012, exhibiting excellent flame-retardant performance; combustion performance complies with JC/T 2028-2018, classifying it as a water-resistant, flame-retardant FFR.

Scope of Application

Architecture field
Roof and wall insulation systems: Thanks to their excellent moisture resistance, they can serve as a facing material for insulation, preventing water vapor from penetrating the insulation layer and compromising its thermal performance. Moreover, their flame-retardant properties enhance the fire safety of buildings, making them suitable for applications such as insulation in steel-framed roofs and walls.
Basement Moisture Protection: Given the humid conditions in basements, this product can be applied to basement walls and floors to prevent moisture from damaging the building structure and interior belongings.
Industrial sector
Cold-Storage Insulation and Moisture Barrier: In cold-storage construction, it is essential to address both thermal insulation and moisture control. This product effectively prevents external moisture from entering the cold storage, thereby maintaining a stable low-temperature environment. Additionally, its flame-retardant properties meet the safety requirements of industrial settings.
Equipment Protection: For certain industrial equipment that requires moisture and fire resistance, this product can be used for protective packaging to safeguard the equipment against moisture and fire hazards.
Other Fields
Warehousing and Logistics: In warehouses, it is used for moisture-proof packaging of goods, particularly for storing humidity-sensitive products such as electronics, food, and pharmaceuticals; its flame-retardant properties also enhance fire safety in the warehouse.
Vehicle and Vessel Interior Decoration: In the interior decoration of ships and vehicles, this material can be used in moisture-proof and fire-resistant applications, such as interior paneling for passenger car compartments and moisture- and fire-resistant treatments for ship cabins.
