Heat Resistant Aluminum Foil Tape 1235-O is specifically designed for HVAC duct sealing, industrial insulation, and reflective barrier applications where temperature resilience and durability are crucial. Made from aluminum alloy 1235 in fully annealed 1235-O temper, this tape combines flexibility, corrosion resistance, and heat endurance, making it an ideal solution for HVAC systems and thermal management applications.
The 1235-O alloy ensures that the tape can conform to curved or irregular surfaces while maintaining long-term adhesion and performance under elevated temperatures. Its reflective surface not only improves energy efficiency but also provides a protective layer against moisture, oxidation, and environmental exposure.
The HVAC, construction, and industrial insulation sectors increasingly rely on heat-resistant Aluminum Tape for efficient and durable duct sealing. With energy efficiency regulations tightening globally, HVAC systems require materials that maintain thermal integrity and prevent heat loss or gain. Aluminum Tape 1235-O fulfills these requirements by providing a reliable barrier that enhances insulation performance.
In construction and refrigeration systems, maintaining temperature stability and preventing air leakage is essential. Aluminum Tape 1235-O ensures airtight sealing of ducts, insulation panels, and thermal barriers, reducing energy consumption and operational costs.
Global market trends also indicate rising demand for recyclable and lightweight materials in industrial insulation and construction applications. Aluminum tape 1235-O addresses both, offering a cost-effective, environmentally friendly, and high-performance solution.
