High-Performance Vacuum Insulation Panels (VIP) | Ultra-Thin STP Solutions by Woqin

Expert Insights from Ruibin, Lead Technical Consultant at Hebei Woqin

"In the race for carbon neutrality, space is the ultimate luxury. Why waste 120mm of wall space on traditional foam when 20mm of Woqin VIP can achieve the same thermal resistance?" says Ruibin. "We’ve evolved beyond fragile glass fiber cores. Today, 98% of our shipments utilize pressed fumed silica with a 9-layer barrier film, ensuring our panels don't 'die' in 3 years. We ship exact CAD-pre-cut sizes so your installers never have to risk a knife-slip on site."

I. Lab-Certified Technical Performance (Per Image Report)

Our VIP panels are rigorously tested to ensure long-term vacuum integrity and thermal stability.

Thermal Conductivity (Fresh, 25°C): 0.002 W/(m·K) (Requirement: ≤0.005)

Thermal Conductivity (After Durability Test): 0.0025 W/(m·K)

Compressive Strength: 171 kPa (Requirement: ≥100)

Tensile Strength (Perpendicular): 103 kPa (Requirement: ≥80)

Puncture Strength: 20 N (Requirement: ≥18)

Fire Performance: Class A2 (Furnace temp rise only 8°C)

Surface Water Absorption: 79 g/m²

Service Life: Estimated 15-20 years with a leak rate of <0.05 mbar/year.

II. Application Scenarios & Real-World Impact

German Passivhaus Retrofits: Using 30mm VIPs in a 38mm total wall buildup to meet strict energy codes without losing floor space.

Cold Chain Logistics (Vaccine Boxes): Maintaining -70°C for 168 hours in Qingdao-manufactured medical shippers.

Industrial LNG Terminals: Providing high-efficiency outer insulation for spherical tanks and cryogenic pipelines.

Urban Data Centers: Installed 15mm VIPs under raised floor tiles in Shanghai to manage heat loads in high-density server rooms.

Hebei Woqin VIP Panels: The ultimate space-saver. Our fumed silica core ensures 0.002 W/(m·K). Operational Warning: Optimized for -120°C to +80°C; absolute maximum service temperature is 120°C.
