In the realm of modern construction, sandwich panel machines have revolutionized the production of composite boards. These machines utilize various core materials, each offering unique properties and advantages. This article delves into the primary sandwich materials used in these machines, highlighting their characteristics and applications.

Diverse Range of Core Materials:

Expanded Polystyrene (EPS): EPS foam boards are created from expandable polystyrene particles. These particles, resembling white pearls, are heated and molded to form closed-cell structure sheets. EPS is known for its lightweight and insulation properties.

Polyurethane (PU): Renowned for its high energy-saving performance, PU offers excellent fire-proof and thermal insulation qualities. Typically, the bulk density of PU used in composite panels ranges from 30 to 40 kg/m³.

Rock Wool Board: Produced from basalt, rock wool is formed through high-temperature melting and high-speed centrifugal processes. It’s a non-combustible material with excellent fire resistance.

Glass Wool: A material characterized by its lightness, heat resistance, and elasticity, glass wool serves as an ideal thermal insulation, fire-proof, and sound-absorbing material in various industries.

Flame-Retardant Paper Honeycomb Panel: This material boasts superior flame retardancy and compressive strength. It carbonizes without burning and releases no toxic substances, making it an eco-friendly alternative to traditional core materials.

Advantages of Using Advanced Sandwich Materials:

The use of these materials in sandwich panel machines leads to the production of panels with exceptional qualities like enhanced insulation, fire resistance, and structural strength.

These materials contribute to the creation of lightweight yet sturdy panels, suitable for a wide range of applications in construction, automotive, and aerospace industries.

Conclusion:
The choice of core material in sandwich panel machines is pivotal in determining the panel’s properties and suitability for various applications. From EPS to flame-retardant paper honeycomb panels, each material offers distinct advantages, making them indispensable in the production of high-quality sandwich panels.
