Kingflex
Engineered for extreme temperature ranges, structural integrity, and maximum fire propagation resistance
Understanding the Critical Nature of BS 476 Compliance in Commercial Infrastructure Projects
Our products undergo rigorous testing according to British Standards (BS 476 Parts 6 & 7), which limit heat propagation, flame spreading, and hazardous smoke emission. Essential for building safety approval.
The highly consistent closed-cell configuration prevents moisture absorption, ensuring long-term thermal conductivity and anti-condensation characteristics on high-humidity pipes.
Exporting to over 66 countries. Our 5 fully automated assembly lines yield over 600,000 cubic meters annually, fulfilling extreme-volume construction demands within deadlines.
British Standard 476 (BS 476) dictates the fire safety testing criteria for building materials and structures. Compliance with Part 6 (Fire Propagation) and Part 7 (Surface Spread of Flame) ensures the elastomeric foam insulation actively impedes flame extension and lowers heat discharge, providing key margins of safety for occupants and structural protection inside high-occupancy environments.
Over 40 Years of Innovation in Energy-Saving Thermal Insulation Materials
Kingflex Insulation Co., Ltd. is a professional manufacturing and trading combo for thermal insulation products. Kingflex research development and production department is located in the well-known capital of green-building materials in Dacheng, China. It is an energy-saving environmentally friendly enterprise concentrating on research, development, production, and sales.
In operation, Kingflex takes energy saving and consumption reduction as the core concept. We provide solutions regarding insulation by means of consultation, research and development production, installation guidance, and post-sale service to lead the development of the global building materials industry.
Kingflex was established by the Jinwei Group, which holds more than a 40-year history. Jinwei Group, established in 1979, was the first manufacturer of thermal insulation materials north of the Yangtze River. Decades of specialized focus have cemented our authority in elastomeric rubber engineering.
Our employees are amazing in their own right, but together they are what makes Kingflex such a fun and rewarding place to work. The Kingflex team is a tight-knit, talented group with a shared vision of giving consistently first-class service for our clients.
Our robust operational team includes: 8 professional engineers in the R&D Department, 6 professional international sales managers, and 230 skilled production technicians.
Equipped with advanced lab apparatuses, we test every batch for thermal conductivity, water vapor permeance, shrinkage, and flammability parameters prior to dispatch.
Modern assembly line processing guaranteeing quality at scale
Kingflex is a designated production enterprise appointed by the Ministry of Energy, the Ministry of Electric Power, and the Ministry of Chemical Industry in China. This proves our critical role in structural and thermal projects globally.
We provide full-system solutions covering mechanical insulation, acoustic control, and high-performance cryogenic systems for HVAC, building envelopes, oil & gas processing, and marine facilities.
Through intensive research, our R&D team optimizes foam cell consistency to lower thermal conductivity and minimize environmental footprint, matching the target requirements of modern green building certifications.
Validated safety performance to satisfy the strictest international codes
Our thermal insulation products are engineered to conform with ASTM, BS 476, CE, REACH, RoHS, UL94, and other international requirements. This ensures that the material can be safely specified for use in airports, hospitals, residential complexes, and deep chemical processing pipelines.

Providing technical information gain to support modern mechanical specifications
Architectural regulations worldwide are placing strict emphasis on fire safety requirements. The integration of high-density mechanical rooms, data centers, and skyscrapers demands structural materials that mitigate combustion. The British Standard BS 476 is recognized across the UK, Middle East, Southeast Asia, and Africa as a key performance indicator.
Specifically, BS 476 Part 7 classifies materials into Class 1 (lowest flame spread) through Class 4 (highest flame spread). Class 0 represents the premier level. It is met only when a material achieves Class 1 in Part 7 and records low thermal propagation in Part 6. By offering Class 0 compliant NBR/PVC elastomeric foam, Kingflex helps procurement agents minimize engineering risks and secure building inspector approvals.
There is an increasing market preference for Halogen-Free Flame Retardant (HFFR) materials. In fire conditions, traditional halogenated fire-retarding elements release toxic smoke and acid gases, which can damage lungs and microelectronics. Kingflex has developed advanced halogen-free alternatives to meet strict toxicological limits. These formulas are designed for cleanrooms, subway systems, and data center facilities.
Modern procurement strategies focus on: Traceability of raw chemical materials, thermal performance longevity, and environmental lifecycle metrics.
Providing engineered answers for challenging operating environments
Minimizes heat gain and loss on large duct systems. The BS 476 Class 0 fire classification allows installation in return-air plenums where smoke controls are highly restrictive. Closed-cell geometry inhibits ambient vapor transmission to prevent mold growth.
Designed for industrial processes, LNG pipelines, and gas liquefaction plants. The material remains flexible and retains thermal insulation properties at low operating temperatures, preventing structural thermal shock.
Designed for mechanical rooms, heavy manufacturing centers, and shipboard engine quarters. The elastomeric composition absorbs sound waves and dampens structural mechanical noise in transmission lines.
Frequently asked questions concerning elastomeric properties, certifications, and compliance
A1: Elastomeric rubber foam insulation is primarily utilized to limit energy loss and prevent condensation on HVAC ductwork, refrigeration piping, chilled water lines, industrial process pipelines, and thermal/acoustic installations within building shells.
A2: Yes, our elastomeric compounds are fire-retardant. They are tested under British Standard 476 Parts 6 and 7 to achieve Class 0 and Class 1 ratings. This ensures safety compliance on demanding commercial projects.
