Kingflex
Explore our leading collection of thermal insulation rolls, pipes, sheets, and low-density closed-cell elastomers engineered for heavy commercial and industrial piping environments.
Understanding the strict micro-technical and macro-financial standards required by procurement specialists across Europe, Latin America, North America, and ASEAN markets.
Global infrastructure developments prioritize ultra-low thermal conductivity (K-value) and ecological certifications. Our NBR/PVC closed-cell elastomeric rubber foams minimize continuous heating and cooling loss, helping projects qualify for strict LEED and BREEAM certifications.
For operations involving chilled water or cryogenic processes, condensation represents structural failure risks, including corrosion under insulation (CUI). A high moisture resistance factor (μ ≥ 10,000) acts as an integrated vapor barrier, protecting the pipe envelope permanently.
Sourcing directly from China's green building materials hub in Dacheng guarantees large-scale production limits. Enterprises maximize ROI through reliable global logistics, standard bulk packaging, and customization protocols for specialized thicknesses (up to 50mm).
In thermal design engineering, "Insulacion de Tuberias" refers to complex thermodynamic boundaries required to prevent thermal transfer. Elastomeric cellular foam achieves this through stable nitrogen micro-bubbles locked in a polymer grid. Our closed-cell percentage exceeding 98% prevents water absorption even under extreme humidity levels.
| Property | Standard Reference | Technical Value / Range |
|---|---|---|
| Thermal Conductivity (λ) | ASTM C518 / ISO 8301 | ≤ 0.034 W/(m·K) at 0 °C |
| Moisture Vapor Permeability | ASTM E96 / BS EN 12086 | μ-value ≥ 10,000 (Water vapor resistance index) |
| Density Range | ASTM D1622 | 40 - 55 kg/m³ |
| Operating Temperature range | EN 14706 / ASTM C411 | -40 °C to +105 °C (Special cryogenic formulations down to -200 °C) |
| Fire Performance Rating | BS 476 Part 6 & 7 / UL 94 | Class 0 / Class 1 / V-0 self-extinguishing |
Custom-engineered thermodynamic solutions matching the operational constraints of global vertical markets.
Condensation forms instantly on modern high-efficiency HVAC equipment. Our elastomeric rubber foam pipes insulate cold lines below ambient temperature, ensuring the exterior air temperature does not fall below the dew point, eliminating water damage in commercial complexes.
Industrial piping networks carry fluids under variable temperatures. Our high-density NBR insulation jackets resist mild acids, oils, and physical wear. Combined with our industrial Rock Wool lines, we cover applications up to high-temperature limits.
Transporting liquid nitrogen, oxygen, or liquefied gases requires specialized insulation systems to prevent extreme cold leakage. Our low-temperature synthetic cryogenic rubber sheets remain flexible at low temperatures, minimizing contraction-induced fractures.

The manufacturing process behind Kingflex closed-cell elastomeric rubber foam.
The process begins with high-grade Nitrile Butadiene Rubber (NBR) and Polyvinyl Chloride (PVC) resins. These materials are combined with flame retardant elements, blowing agents, and chemical stabilizers in a high-shear internal mixer.
Our automated extruders force the compound through specialized dies to yield tubes of precise inner diameters and thickness configurations. Sheets are extruded using wide-mouth die plates to maintain density consistency across the cross-section.
Extruded materials pass through multi-zone vulcanization tunnels. Heat activates the chemical blowing agents, generating millions of microscopic, non-communicating cells filled with inert nitrogen gas. This achieves the target insulation rating.
