Common Specifications
*Density: 48–80 kg/m³
*Thickness: 25–100 mm
*Inner diameter: 15–1200 mm (can be customized)
*Length: 1000 mm or 1200 mm
*Facings: Aluminum foil, fiberglass cloth, etc.
Key Advantages:
* Perfect for pipe insulation – fits tightly around pipes of different diameters
* Low thermal conductivity – reduces heat loss and energy costs
* Good fire resistance – protects pipes and surrounding areas
* Water repellent – prevents moisture absorption
* Easy to install – can be cut and wrapped quickly
