Product Specifications

Product Structure

This facing material is composed of a flame-retardant polypropylene composite combined with a flame-retardant polyester film and a densely arranged reinforcement mesh. It typically features a multilayer structure, which may include an outer layer of flame-retardant metallized polypropylene film, a middle layer of flame-retardant polyester film, and an inner layer of reinforced, densely spaced mesh. The individual layers are bonded together using a specialized adhesive process, resulting in a unified facing material with excellent overall performance.

Material Properties

Flame-retardant polypropylene exhibits excellent chemical stability, mechanical properties, and flame-retardant performance, effectively inhibiting flame spread and meeting the relevant flame-retardant standards. Flame-retardant polyester film, on the other hand, boasts high heat resistance, moisture resistance, and good flexibility, thereby enhancing the overall performance of the laminated surface. The incorporation of reinforced stiffening ribs further improves the product’s tensile strength and tear resistance; under external forces such as pulling or impact, these ribs effectively distribute stress, preventing damage and cracking.

Physical Properties

It exhibits a low water vapor permeability, effectively preventing water vapor penetration and providing excellent moisture resistance, thereby protecting the internal insulation materials and other structural components from moisture-induced damage. Moreover, it boasts outstanding tensile strength and burst strength, ensuring structural integrity and stability across a wide range of service environments.

Product Features

It exhibits outstanding fire-resistant performance, meeting the relevant fire-rating requirements and effectively slowing the spread of fire in the event of a blaze, thereby buying valuable time for evacuation and firefighting operations. Moreover, thanks to its material properties and structural design, it boasts excellent durability and weather resistance, making it highly resistant to aging and degradation caused by external environmental factors.

Application Fields

It is primarily used for thermal insulation and moisture-proofing in the construction sector, such as roof and wall insulation systems, and can be paired with insulation materials like rock wool and glass wool. In addition, it holds broad application potential in industrial equipment and pipeline insulation that demand high levels of fire resistance and moisture protection, as well as in specialized environments such as refrigeration and freezing applications.
