Our Rhombus Reinforced Aluminum Foil sets a new standard in thermal insulation with its triple-layer composite structure, optimized for maximum efficiency, durability, and versatility:

1st Layer: VMPET (Metallized PET) – Heat Reflection
Ultra-thin (12μm) metallized PET film with 99% pure aluminum coating for superior infrared heat reflection (＞95%, ASTM E2592).
Excellent moisture and oxygen barrier (MVTR ≤0.05g/m²·24h, ASTM E96).

2nd Layer: High-Strength Fiber Mesh – Reinforcement
Rhombus-pattern polymer fiber mesh provides 300% greater tear resistance vs. traditional aluminum foils.
Withstands 25N/cm² compression without deformation, ideal for rugged industrial applications.

3rd Layer: VMPET (Metallized PET) – Seamless Protection
Secondary metallized layer enhances heat reflection and prevents condensation-induced corrosion.
Electromagnetic shielding capabilities (up to 60dB attenuation).

Key Benefits & Technical Superiority

Unmatched Thermal Efficiency
Reflects 95% radiant heat, reducing HVAC energy costs by 30%+.
Stable performance in extreme temperatures (-70°C to 200°C, IEC 60068-2-14 certified).

Ultra-Durable & Lightweight
40% lighter than fiberglass insulation, reducing shipping costs.
Resists punctures, abrasion, and delamination (tested per ASTM D882).

Eco-Friendly & Safe
RoHS & REACH compliant with 30% recycled aluminum content.
Fire-retardant (UL94 V-0 rated) for construction and EV battery applications.
