Kingflex is established by Jinwei Group with more than 45 years history. Established in 1979 as the first manufacturer of thermal insulation materials north of the Yangtze River.
A tight-knit, talented group with a shared vision of giving consistently first-class service with 8 professional R&D engineers, international sales, and expert production crew.
Equipped with 5 large automatic assembly lines, producing over 600,000 m³ annually, designated by energy and chemical ministries.
Navigating high-temperature resilience, energy transition, and semantic market demands in modern engineering.
In the contemporary landscape of industrial manufacturing, petrochemical processing, and commercial construction, thermal efficiency dictates operational profitability and environmental compliance. While elastomeric foam excels in cold insulation and HVAC anti-condensation, Mineral Wool Insulation remains the undisputed backbone for extreme high-temperature environments, fire-rated assemblies, and heavy industrial piping systems. Across North America, Europe, and emerging Asia-Pacific markets, stringent building codes and net-zero carbon initiatives mandate high-performance insulation that simultaneously optimizes thermal resistance (R-value) and provides Class A fire protection.
Modern engineering projects require integrated solutions combining thermal insulation, cold insulation, and noise reduction. Our manufacturing paradigm bridges traditional craftsmanship with advanced automation. By implementing computerized fiber-spinning controls, binder distribution algorithms, and eco-curing ovens, we achieve superior tensile strength and low shot content in mineral wool products. This technological roadmap guarantees long-term dimensional stability under thermal shock, preventing sag or compression in vertical wall applications and extensive industrial boiler ducting.
Industrial deployment spans multiple demanding sectors:
Expert answers regarding elastomeric and mineral wool insulation selection, compliance, and application.
A1: It is mainly used for HVAC ducts, air conditioning pipes, building thermal insulation, industrial pipeline cold insulation, and sound insulation due to its excellent closed-cell moisture resistance.
A2: Yes, our rubber foam insulation products are fire retardant, meeting stringent safety standards for modern building and industrial projects.
A3: Rubber foam is flexible, closed-cell, and moisture-proof, ideal for HVAC and cold/chilled water systems. Rock wool is high-temperature resistant and fireproof, designed for industrial high-temperature pipelines and extreme heat.
A4: Yes, we fully support OEM and ODM services to meet diverse project specifications and specialized dimensions.
A5: Our products have successfully passed BS 476, CE, REACH, ROHS, UL94, ASTM, and other major international compliance certifications.
A6: Yes, all batches undergo strict quality control with complete manufacturing traceability.
A7: We produce thickness ranges from 6mm up to 50mm to match varied engineering insulation requirements.
A8: Under standard operational conditions and proper installation, the expected service life is approximately 10 to 15 years.
