Double Bright Surface Laminated Aluminum Foil for PU Foam Thermal Insulation

1. Product Introduction

Developed exclusively for polyurethane (PU) foam lamination and composite processing, this double-sided mirror bright aluminum foil is crafted from premium 8011-O and 1235-O aluminum alloys. Manufactured via precision rolling and full annealing processes, it delivers ultra-smooth double mirror surfaces, consistent thickness and superior flatness. The material integrates outstanding thermal insulation, vapor resistance, waterproofing and anti-corrosion capabilities, serving as a reliable functional layer for PU foam composites.

It boasts excellent adhesive compatibility with various PU foam substrates. After lamination, the foil stays firmly bonded without delamination, cracking or blistering. Its physical performance remains stable across a wide temperature range. The sleek double bright surface features strong oxidation resistance and facilitates follow-up cutting, slitting and forming work, making it an optimal core material for all types of PU foam thermal insulation products.

6. Frequently Asked Questions

1. Q: What are the advantages of double bright surface aluminum foil?

   A: Different from single-sided bright foil, both sides present uniform mirror finish with high smoothness. It features better oxidation resistance and superior thermal reflection performance, while delivering a more attractive appearance.

2. Q: Can I customize the thickness and width?

   A: Yes. We provide personalized customization on thickness, width, roll length and roll weight to fit your PU foam lamination requirements.

3. Q: Is it applicable for long-term outdoor use?

   A: Absolutely. The foil has good anti-oxidation, UV resistance and corrosion resistance, and can maintain stable performance for outdoor insulation applications.

4. Q: Which lamination processes is the foil compatible with?

   A: It works perfectly with dry lamination, hot press lamination and glue coating processes for PU foam materials.

5. Q: Is the double bright surface easy to get scratched?

   A: We apply dedicated surface protection and professional packaging. The foil will not be scratched under normal lamination and construction operations.

6. Q: What is the minimum order quantity?

   A: Regular sizes are available for small trial orders. The MOQ for customized specifications can be negotiated.
