Core Performance of PIR Pre-insulated Ducting Foam Panel
1. Waterproof, Moisture-proof and Corrosion Resistance
The ultra-high closed-cell structure has its own waterproof and moisture-proof properties, with an extremely low absorption rate, preventing the failure of the insulation layer due to water absorption. It is resistant to acid and alkali, does not mold, does not breed bacteria, and the surface protective layer is resistant to corrosion and aging, not afraid of damp basements, underground pipe galleries, food factories, etc., with a service life of over 20 years, and basically requires no later maintenance.
2. Environmental and Health Attributes
The product does not contain harmful substances such as formaldehyde, Freon, benzene, etc., no dust shedding, no odor, the chemical properties of the material are stable, recyclable, and in line with green building environmental standards, suitable for places with high air cleanliness requirements such as hospitals, laboratories, clean rooms, etc.
