Select from our industry-grade NBR/PVC closed-cell thermal solutions, factory-tested to meet global HVAC, plumbing, and cryogenic requirements.
In modern industrial architectural engineering, thermal insulation is no longer evaluated solely by static thermal resistance (R-value). Instead, total life-cycle performance, moisture-barrier protection, installation velocity, and fire resistance serve as the metrics of project cost-efficiency. High-density, self-adhesive elastomeric sheets are now critical components in large-scale infrastructure construction, HVAC manufacturing, cold-chain containment, and petrochemical piping installations.
"Integrating pressure-sensitive backing directly onto closed-cell elastomeric rubber foam decreases labor overhead by up to 45% while completely removing the reliance on VOC-heavy liquid contact adhesives in confined construction environments."
As green building codes like LEED, BREEAM, and DGNB dictate construction standards worldwide, raw materials must satisfy strict criteria for thermal conductivity (λ ≤ 0.034 W/m·K at 0℃) and indoor air safety. Our self-adhesive sheets utilize low-emissivity pressure-sensitive adhesives that emit minimal VOCs, complying with global environmental mandates.
Traditional elastomeric foam installations require manual application of solvent-borne adhesives. This approach is susceptible to human error, uneven coverage, and adhesive breakdown under extreme thermal cycling. Our factory-applied self-adhesive backings use a high-tack acrylic copolymer reinforced with a glass scrim mesh. This setup ensures strong structural adhesion across metal, PVC, and fiberglass substrates, preventing delamination over long-term operations.
Advanced Closed-Cell Foaming Production Line
Kingflex Insulation Co., Ltd. is a specialized manufacturing and trading combo for high-performance thermal insulation products. Our research, development, and primary production departments are situated in Dacheng, China—a hub for energy-saving, eco-friendly building materials. At Kingflex, we focus on energy conservation, providing full consulting, customized manufacturing, and field-installation guidance for projects worldwide.
Established under the Jinwei Group, which holds over 40 years of industrial history since its founding in 1979, Kingflex built its legacy on robust quality. We were the first manufacturer of thermal insulation materials north of the Yangtze River. Today, we operate 5 automated assembly lines, producing over 600,000 cubic meters annually.
Designed for durability and thermal efficiency, our NBR/PVC closed-cell structure delivers reliable performance in temperatures ranging from -40°C to +105°C.

Advanced continuous vulcanization ensures a closed-cell rate exceeding 98%. This minimizes convection currents inside the micro-cavities, keeping thermal conductivity stable over years of operation.
Instead of manual contact cementing, our sheets feature factory-applied pressure-sensitive adhesive. This backing is protected by a peel-off release liner, ensuring consistent adhesion even in high-humidity conditions.
Alumina trihydrate (ATH) and halogenated flame retardants are integrated directly into the polymer matrix. When exposed to fire, they release water vapor to cool the surface and form a protective char barrier.
Our self-adhesive thermal insulation sheets are engineered for diverse environments, offering excellent thermal management, moisture resistance, and acoustics:
Our materials undergo regular testing by independent labs to verify their physical, thermal, and fire performance against leading international safety codes.
Our success is built on collaboration. The Kingflex team brings together expert R&D engineers, quality assurance inspectors, and global logistics specialists to support your projects from planning through to delivery.
We work closely with contractors to provide custom thicknesses, tailored widths, and project-specific adhesive formulations designed to withstand unique local climates—from hot desert sites to humid tropical locations.
