Aluminium + LDPE laminate for thermal insulation
Aluminium + LDPE laminate for thermal insulation
Aluminium + LDPE laminate is a multi-layer material engineered to provide efficient thermal insulation, moisture protection, and mechanical durability. It combines the reflective properties of aluminium foil with the flexibility and sealing strength of Low-Density Polyethylene (LDPE), creating a versatile barrier material widely used in insulation and packaging industries.
The aluminium layer plays a crucial role in reflecting radiant heat. Aluminium has excellent thermal reflectivity, which helps reduce heat transfer by reflecting a large portion of infrared radiation. This property makes the laminate highly effective for maintaining temperature stability in insulation systems such as HVAC ducts, building insulation, and industrial thermal protection.
The LDPE layer adds flexibility, toughness, and strong bonding capability to the laminate. LDPE acts as a protective coating that enhances tear resistance and prevents damage during handling or installation. It also creates an effective moisture and vapor barrier, preventing water vapor penetration that can reduce insulation efficiency.
