Premium aluminum foil tape with aggressive acrylic adhesive, high heat reflectivity, and exceptional durability for industrial HVAC, sealing, and thermal protection applications across extreme temperature ranges.
3M™ Aluminum Foil Tape 34383 is a premium general-purpose, durable acrylic adhesive tape engineered to protect heat-sensitive components from moisture, vapor, UV damage, harsh weather, and chemical exposure. This high-performance foil tape features aggressive acrylic adhesive technology that delivers excellent performance across a wide range of temperatures, from -40°F to 260°F (-40°C to 127°C). The tape's exceptional heat and light reflectivity provides superior thermal conductivity, making it ideal for heating and cooling efficiency applications while protecting components from UV degradation.
The malleable aluminum foil construction with 2.8 mil high-strength backing and 1.7 mil acrylic adhesive layer conforms perfectly to irregular shapes and surfaces, ensuring reliable adhesion on complex geometries. This versatile tape can be easily torn by hand without requiring any tools, providing fast and safe application for both interior and exterior seams, joints, HVAC ductwork, and sealing applications. The self-wound design eliminates the need for complex installation procedures while maintaining consistent performance.
Designed for industrial and occupational use, 3M™ Aluminum Foil Tape 34383 demonstrates exceptional resistance to flame, moisture, weather conditions, UV radiation, and most chemicals, ensuring long-lasting durability in demanding environments. With 11% elongation at break and 30 lb/in tensile strength, this professional-grade tape delivers dependable solutions for tough applications in aerospace, appliance manufacturing, construction, specialty vehicles, and transportation industries. Each case contains 36 rolls of 60-yard length, providing comprehensive coverage for large-scale projects.
