Product Description
Expanded vermiculite insulating boards are manufactured from carefully selected, high-quality natural vermiculite ore. The raw material undergoes strict grading, high-temperature exfoliation, and advanced dry-pressing processes to ensure consistent quality and reliable performance. This precise production method results in a lightweight yet durable board with a uniform structure and excellent mechanical strength.
These boards provide outstanding thermal insulation performance, effectively reducing heat loss and improving energy efficiency in high-temperature environments. In addition, they offer excellent fire resistance, low thermal conductivity, and strong resistance to thermal shock, making them suitable for continuous operation under demanding conditions. Their dimensional stability ensures minimal deformation even when exposed to extreme temperatures.
With a completely inorganic composition, expanded vermiculite boards are non-toxic, non-combustible, and free from any volatile emissions. This makes them an environmentally friendly and safe solution, particularly suitable for applications with strict hygiene and safety requirements.
Thanks to these advantages, expanded vermiculite insulating boards are widely used as backing insulation materials in food processing machinery, aluminum electrolytic cells, industrial furnaces, kilns, and other high-temperature industrial equipment. They help enhance operational efficiency, extend equipment service life, and reduce overall energy consumption, making them a reliable and cost-effective choice for modern industrial insulation applications.
Product Advantages
- Ultra-Lightweight: With a density of only 430-480 kg/m³, it significantly reduces the overall structural load on the furnace.
- Excellent Thermal Stability: Exhibits extremely low shrinkage at high temperatures, possesses superior thermal shock resistance, and is highly resistant to cracking.
- Chemical Neutrality: Asbestos-free; it emits no harmful gases when heated, thereby complying with modern environmental protection and occupational health standards.
- Ease of Processing: On-site installation is remarkably simple; it can be precisely shaped-including sawing, drilling, and planing-using standard woodworking tools.
