Explore our main lines of elastomeric rubber foam insulation sheets and tubes designed for HVAC and industrial piping systems.
Thermal insulation in refrigeration, cryogenic, and HVAC engineering is heavily influenced by the second law of thermodynamics. Moisture naturally flows from the warm external environment toward cold pipe surfaces. If the insulation barrier lacks sufficient water vapor diffusion resistance (μ value), moisture permeates, leading to condensation, dramatic reduction in thermal resistance, mold growth, and under-insulation corrosion.
As a leading China LT insulation tube manufacturer, Kingflex implements highly optimized closed-cell chemical processing technology. With an even distribution of air cells and a closed-cell rate exceeding 98%, our NBR/PVC elastomer insulation stops moisture infiltration. Kingflex materials guarantee a low thermal conductivity coefficient (λ ≤ 0.034 W/(m·K) at 0°C) and robust physical performance within the range of -40℃ to 105℃.
A trusted global supplier of advanced thermal insulation systems with over 40 years of manufacturing history.
Kingflex Insulation Co., Ltd. is a professional manufacturing and trading combo for thermal insulation products. Kingflex's research development and production departments are located in Dacheng, China, a widely recognized hub for green building materials.
