Expanded perlite is a lightweight, versatile, and eco-friendly material that has gained popularity in various industries due to its exceptional properties. It offers a low apparent density, excellent thermal insulation, strong chemical stability, and can withstand a wide range of temperatures. Additionally, it has low moisture absorption, is non-toxic, odorless, fire-resistant, and provides good sound insulation. These features make it ideal for use in construction, industrial applications, and more.

The expanded perlite fireproof board is an innovative core filling material used in fireproof doors. It is manufactured using expanded perlite as the main component, combined with a pre-embedded skeleton and a suitable adhesive as a binder. This combination enhances structural integrity while maintaining fire resistance and thermal performance.

**Basic Manufacturing Process:**

1. **Material Selection:** High-quality expanded perlite is chosen as the primary material, along with a suitable skeleton and a binder that meets all required testing standards. 2. **Mixing:** The binder is added to the perlite, and the mixture is thoroughly blended using a specialized mixer to ensure uniformity. 3. **Pressurization:** The mixed material is placed into molds or door cores and then subjected to pressure to shape it properly. 4. **Curing & Packaging:** After molding, the product is left to dry naturally, and once fully cured, it is packaged as a finished product ready for distribution.

Currently, expanded perlite fireproof boards are available in several quality grades, catering to different application needs. Whether for commercial buildings, residential structures, or industrial facilities, these boards offer reliable fire protection and insulation solutions.
