2. Wide operating temperature range: standard models remain stable between -30°C and 80°C, while the premium F50 model operates between -40°C and 110°C and withstands momentary high temperatures. It is suitable for applications such as high-temperature exhaust ducts and the external cladding of industrial equipment.
1. The dense, non-porous aluminum foil structure ensures extremely low water vapor permeability. It effectively blocks outdoor moisture and rainwater from penetrating the insulation layer, fundamentally preventing issues such as condensation, dampness, mold growth, and insulation failure.
2. The aluminum foil surface is completely hydrophobic and offers basic water-seepage resistance; it performs reliably in high-humidity environments—such as roofs, basements, and outdoor exposed piping—thereby reducing costs associated with future maintenance and rework.
1. The finished product is classified as an A2-grade flame-retardant material; it does not produce open flames or molten droplets during combustion and emits low levels of smoke. When paired with A-grade insulation wool, it forms a comprehensive fire-resistant enclosure system that meets fire safety acceptance standards for industrial plants and energy storage stations.
2. Formulated with UV-resistant additives, the material resists chalking, cracking, and delamination even after 5 to 10 years of outdoor exposure, ensuring a long service life in sun-exposed settings such as coastal areas and rooftops.
1. It securely encapsulates the insulation board, locking in internal fibers to prevent the release of airborne particles (such as glass wool or rock wool dust) during installation; this improves the on-site working environment and ensures a neat, aesthetically pleasing finish for exposed piping and mechanical room surfaces.
2. Featuring an integrated fiberglass reinforcement layer, the material offers high toughness, tear resistance, and durability against abrasion and punctures. It is resistant to damage during handling and installation, effectively protecting the inner insulation core and extending the service life of the entire insulation system.
3. The material is lightweight, thin, and flexible, allowing it to be bent freely and fit snugly against curved pipe surfaces, beam/column corners, and irregularly shaped equipment bases, ensuring complete coverage even in complex installation scenarios.
The high-purity aluminum foil composite layer resists corrosion from weak acids, weak alkalis, and salt spray, and does not oxidize or rust. It maintains stable performance over the long term in chemical workshops, coastal plants with high salt-spray exposure, and mildly corrosive industrial environments, ensuring that its vapor-barrier and reflective properties remain intact despite exposure to corrosive agents.
1. The surface is smooth and glossy, eliminating the need for additional decorative cladding on exposed mechanical room components or ventilation ducts; the material provides a neat, finished look on its own, thereby reducing the need for secondary finishing steps. 2. It can be factory-laminated directly with glass wool, rock wool, or rubber-plastic insulation; on-site cutting, wrapping, and installation are simple, significantly shortening construction schedules for HVAC and steel structure insulation projects.
1. The aluminum foil surface has low hardness and is easily punctured by sharp, hard objects; moisture and heat can rapidly penetrate damaged areas, so protective measures are essential during installation and subsequent maintenance.
2. Seams between rolls must be completely sealed using specialized aluminum foil sealing tape; exposed gaps create pathways for moisture and heat flow, drastically reducing overall vapor barrier and thermal insulation performance.
3. It offers only mild resistance to acid and alkali corrosion; prolonged immersion in highly acidic or alkaline wastewater environments causes delamination and failure. In severely corrosive conditions, an additional specialized anti-corrosion protective layer is required.
