Aluminum Alloy 8079 Aluminum Foil for Car Heat Insulation Sheets (0.02–0.05 mm | Custom Width | Heat Reflective Coating)

Introduction

The 8079-O ultra-high-purity aluminum foil with automotive-grade heat-reflective coating (0.02–0.05 mm thickness, 600–1650 mm customizable width, nano-ceramic + IR-reflective + adhesive layer) is the global automotive industry’s No.1 material for firewall, roof, floor and battery thermal insulation sheets.

• Alloy 8079-O: purity > 99.99 %, pinhole ≤ 20 pcs/m², elongation > 13 %.

• Heat-reflective coating: infrared reflectivity ≥ 97 %, emissivity ≤ 0.03, withstands 200 °C continuous.

• Meets FMVSS 302, ECE R118, GB 8410 automotive fire standards.
  Result: insulation that cuts cabin temperature by up to 18 °C in summer sun, reduces HVAC load 30 %, and installs 70 % faster than traditional felt or foam.
