Key Applications (By Industry)
Highlight these scenarios in your product listing to match buyer pain points:
1. HVAC & Refrigeration Industry
Pipes & Ducts: Insulates cold/hot water pipes, air conditioning ducts, and refrigeration pipelines (e.g., supermarkets, cold storage). Prevents condensation (WVTR ≤0.1 g/(m²·24h)) and reduces energy loss (thermal conductivity ≤0.033 W/(m·K)).
Equipment: Wraps air conditioner compressors and heat exchangers—resists high temperatures (up to 105℃) and reduces noise (sound absorption coefficient ≥0.3 at 500Hz).
2. Construction Industry
Indoor Insulation: Used for wall, ceiling, and floor insulation in residential buildings, hospitals, and schools. Low formaldehyde emission (≤0.1 mg/m³) and flame resistance (ASTM E84 FSI ≤25) ensure indoor safety.
Outdoor Insulation: Applied to external walls and roof ducts—waterproof (water absorption ≤0.5%) and UV-resistant (optional UV coating for 5-year outdoor service life).
3. Industrial & Transportation
Industrial Equipment: Insulates oil pipelines (nitrile material resists oil corrosion) and chemical tanks (acid/alkali resistance).
Marine & Automotive: Marine cabin insulation (meets IMO SOLAS standards) and automotive HVAC systems (lightweight, density 40-60 kg/m³, reduces vehicle load).
4. Cold Chain Logistics
Insulates refrigerated trucks, shipping containers, and freezer warehouses—maintains stable low temperatures (-50℃ ~ +5℃) and prevents condensation (closed-cell structure).
