Explore our premium selection of industrial-grade insulation rolls, sheets, and tubes manufactured to global standards.
Kingflex Insulation Co., Ltd. is a professional manufacturing and trading combo for thermal insulation products. Our research development and production center is strategically situated in Dacheng, China—the capital of green-building materials. As an energy-saving and environmentally friendly enterprise, we concentrate on the research, development, production, and worldwide sales of advanced insulation solutions. By prioritizing consumption reduction, we provide expert structural advisory, R&D production, installation guidance, and dedicated post-sale service.
Established by the renowned Jinwei Group, which boasts more than 40 years of industrial history (founded in 1979), Kingflex inherits pioneering composite expertise. We stood as the first manufacturer of thermal insulation materials north of the Yangtze River, paving the way for today's high-tech sandwich panel manufacturing standards.
Our collaborative team is united by a shared vision to deliver first-class services. Kingflex houses 8 professional engineers in our dedicated R&D Department, supported by 6 international trade specialists, and a robust workforce of 230 skilled production employees operating our state-of-the-art facilities.
Analyzing the paradigm shift in heavy industrial, cold-chain transport, and architectural cladding sectors towards lightweight GRP structures.
Global architectural standards demand systems with low embodied carbon and superior R-values. GRP (Glass Reinforced Polyester) sandwich panels using PU, PIR, or modified elastomeric rubber cores prevent thermal bridges, drastically reducing HVAC operational emissions.
Unlike steel or aluminum sheets, GRP skins are inert to electrochemical oxidation, high salinity, and aggressive chemical cleaners. This renders them critical for high-hygiene food processing facilities and marine structures.
Recent developments integrate closed-cell elastomeric rubber foam and rock wool cores within GRP structural skins. This combines chemical impact resistance with elastomeric vibration damping and thermal properties.

Detailed technical and business answers concerning Kingflex products and custom panels.
What is elastomeric rubber foam insulation used for?
It is primarily used for commercial HVAC ducts, chilled/hot air conditioning pipes, high-efficiency building thermal insulation, industrial pipeline cold insulation, and acoustic sound isolation systems.
Is Kingflex rubber foam insulation fire resistant?
Yes. Our rubber foam insulation materials integrate flame-retardant additives, achieving self-extinguishing performance that complies with national and international fire safety codes (such as BS 476 Class 0 and UL94).
What is the difference between rubber foam and rock wool insulation?
Rubber foam features a highly flexible, closed-cell structure with built-in moisture protection, making it excellent for prevention of condensation on HVAC and cold pipelines. Rock wool is an open-fiber mineral product designed for high-temperature resistance and fire protection, and is frequently integrated as a core structural element for non-combustible partition walls.
Do you provide customized insulation products?
Yes, we support comprehensive OEM/ODM engineering services. We tailor density, thickness, thermal conductivity thresholds, and outer protective skins (such as GRP cladding layers) to match specific project specifications.
What certifications do your products have?
Our products have successfully passed rigorous evaluations for BS 476, CE, REACH, RoHS, UL94, and ASTM. This guarantees compliance with quality and safety regulations across Europe, North America, the Middle East, and Asia-Pacific markets.
Does Kingflex products have traceability?
Yes. Every batch manufactured is logged with a specific QR identifier and batch tracking code, linking the final product back to the raw chemical input processing metrics for quality assurance.
What thickness of Rubber foam insulation sheet roll can you produce?
Our automated extrusion lines produce continuous sheets ranging from 6mm up to 50mm in thickness.
What is the service life of rubber plastic pipe and board?
Under normal design parameters and standard operating conditions, Kingflex insulation components maintain their thermal efficiency and structural integrity for approximately 10 to 15 years.
High-performance industrial solutions for acoustic isolation, low-temperature systems, and specialized industrial piping.
