View PricelistIn modern commercial HVAC, district energy networks, and process industries, mechanical engineers face a persistent challenge: thermal bridging at pipe support locations. When standard metallic pipe securing brackets clamp directly onto bare metal pipes, they create a highly conductive thermal escape path. This results in localized energy loss and critical condensation risks.
Kingflex solves this challenge by developing structural insulation support inserts and brackets that interface seamlessly with NBR/PVC elastomeric rubber foam. Our systems feature high structural compressive strength, outstanding low thermal conductivity, and a moisture barrier that maintains continuous system integrity.
Based in Dacheng, the world-renowned green building material capital of China, Kingflex operates state-of-the-art automated manufacturing lines that deliver unparalleled capacity and absolute precision.
Established by the Jinwei Group (which carries a prestigious history dating back to 1979 as the pioneer manufacturer of thermal insulation materials north of the Yangtze River), Kingflex has continually invested in continuous-foaming automation.
By standardizing raw material formulation and mechanical extrusion processes, we ensure that every batch of NBR/PVC elastomeric foam and insulated pipe support brackets meets strict international engineering standards. This high production capability ensures fast turnaround times for bulk orders from international EPCs and major mechanical distributors.
Selecting the correct insert core material inside pipe securing brackets is vital to balance thermal resistance and structural load-bearing capacity.
| Performance Metrics | High-Density NBR/PVC Insert | Structural PIR / Polyurethane | Mineral Rock Wool (High Density) |
|---|---|---|---|
| Thermal Conductivity (λ at 0°C) | ≤ 0.034 W/(m·K) | ≤ 0.028 W/(m·K) | ≤ 0.040 W/(m·K) |
| Moisture Resistance (μ value) | ≥ 10,000 (Closed Cell) | ≥ 3,000 (Closed Cell) | 1 (Open Structure - Needs Vapor Barrier) |
| Working Temp. Range | -40°C to +105°C | -180°C to +120°C | Up to +650°C |
| Compressive Resistance | Moderate (Excellent cushioning) | Very High (Structural load bearing) | Moderate to High |
| Best Applications | HVAC, Chilled/Hot Water Lines | Heavy Load-bearing supports, Cryogenics | High Temp Steam, Industrial Boilers |
Our current R&D focuses heavily on zero-ODP (Ozone Depletion Potential) and zero-GWP (Global Warming Potential) blowing agents. Future product lines include pre-integrated IoT temperature sensors within high-density thermal pipe brackets to provide continuous real-time monitoring of thermal envelope integrity.
By coupling open-cell and closed-cell rubber technology, Kingflex brackets decouple acoustic vibrations originating from inline fluid pumping. This ensures noise suppression compliance in commercial spaces like hospitals, administrative complexes, and hotels.
