High Barrier Aluminum Foil (0.03–0.12mm) for Building & Automotive PU Foam

1. Product Overview

This high-quality aluminum foil is professionally engineered for lamination and composite bonding with polyurethane (PU) foam. Manufactured from premium aluminum ingots via precision rolling and full annealing processes, it delivers balanced mechanical performance and outstanding comprehensive functionality. Featuring high tensile strength and superior flexibility, the foil achieves tight, stable bonding with PU foam substrates. It will not delaminate, crack or warp after long-term use. With excellent heat insulation, waterproof and anti-corrosion properties, it maintains stable physical performance across a wide temperature range. It is a reliable core material for thermal insulation, ventilation, construction and automotive PU foam composite products.
