Explore our top-tier NBR/PVC elastomeric products engineered for cold-chain, acoustics, and high-performance temperature control.
Traditional piping insulation is black, which works well for hidden systems but introduces operational complexities in modern plants and mechanical rooms. Red Rubber Foam Insulation Tubing provides a critical visual differentiation, signifying high-temperature lines, hot water distribution networks, fire protection mains, or bypass circuits. This helps prevent maintenance team errors, speeds up emergency shutdowns, and enhances compliance with global safety standards.
Engineered from high-density, closed-cell NBR (Nitrile Butadiene Rubber) and PVC blends, our red insulation tubes provide exceptional thermal resistance. The integrated color formulation ensures that the visual indicator will not fade, peel, or crack under high thermal loads or exposure to ultraviolet radiation in industrial environments.
By integrating visual management directly into the insulation layer, facilities eliminate the labor-intensive secondary step of color-coding pipes with plastic tapes or wraps. This directly lowers installation costs while maintaining superior thermal protection and flame-retardant safety.
Established as a cornerstone of national energy conservation projects, Kingflex Insulation represents the pinnacle of China's green-building material industry.
Kingflex Insulation Co., Ltd. is a professional manufacturing and trading combo for thermal insulation products. Our state-of-the-art research development and production department is situated in the well-known capital of green-building materials in Dacheng, China. As an energy-saving, environmentally friendly enterprise, we concentrate on the complete lifecycle of our products—from R&D and large-scale manufacturing to international sales, installation guidance, and post-sale service.
Kingflex is established by the Jinwei Group, which boasts a rich history of more than 40 years. Founded in 1979, the Jinwei Group was the first manufacturer of thermal insulation materials north of the Yangtze River. Decades of specialized focus have empowered us to supply the global building materials and petrochemical industries with high-performance insulation systems.
Our advanced production hubs deliver high quality, reliable supply chains, and cost efficiencies for commercial HVAC and industrial piping projects.
Operating five large automatic assembly lines allows us to produce over 600,000 cubic meters annually. This high-capacity output ensures rapid fulfillment of bulk global orders without compromising quality standards.
Our close proximity to raw chemical supply chains in China allows us to optimize NBR/PVC polymer formulations. This provides high closed-cell ratios (>98%) and consistent color quality across production batches.
Our products meet BS 476, CE, REACH, RoHS, UL94, and ASTM requirements. Every production run is fully traceable, guaranteeing compliance with local safety regulations across regional markets.
Our dedicated Research & Development department includes eight professional engineers focused on improving thermal performance, flame retardancy, and low-temperature durability.
Whether you require custom dimensions for large-diameter pipelines, specific density ratings (40-55 kg/m³), or specific red jacket formulations for outdoor UV resistance, our R&D team can develop custom formulations to meet your application demands.
Our red and black rubber foam insulation systems are engineered to perform under demanding conditions (-40℃ to 105℃).

The thermal conductivity of our elastomeric foam remains low and stable over time, thanks to the uniform micro-cellular structure. Our red rubber foam insulation tubes resist moisture penetration, eliminating the risk of Corrosion Under Insulation (CUI) on copper or carbon steel pipes.
Additionally, the material's compression resilience of over 80% ensures the tubes retain their thickness at joints, bends, and hangers, maintaining continuous thermal performance across the entire pipeline.
Our color-coded elastomeric insulation is designed for easy installation and reliable performance in diverse environments.
Perfect for commercial air-conditioning systems to prevent condensation on cold lines while distinguishing hot-water loop returns. Red foam makes it easy to identify fluid-carrying lines behind maintenance panels.
Used on hot water pipes connected to rooftop solar collector arrays. The red insulation is formulated with UV stabilizers, providing high resistance to environmental weathering.
Ideal for chemical plants and food production facilities to insulate steam lines, process water pipes, and condensate drains. The material helps protect personnel from burns and prevents corrosion in wet processing areas.
Our commitment to quality is backed by third-party testing and verified customer feedback.
We perform quality control checks at every stage, from raw NBR blending to final extrusion. Our products are certified by international organizations, ensuring they meet rigorous global building codes:
We work closely with global buyers, MEP contractors, and industrial distributors to deliver consistent quality and reliable lead times. Our customer support team handles container configurations and custom export packaging to ensure products arrive safely.
