Explore our primary selection of certified elastomeric materials, engineered to mitigate fire risk, minimize smoke toxicity, and deliver superior thermal barrier efficiency.
In modern commercial, industrial, and residential construction, fire safety standards are evolving rapidly. Conventional elastomeric insulation materials typically utilize halogenated fire retardants (containing chlorine or bromine) to satisfy fire classification standards. However, in the event of a fire, halogenated substances undergo thermal decomposition, releasing highly toxic, corrosive hydrogen halide gases (such as HCl and HBr) alongside dense, suffocating smoke.
Halogen-Free Insulation Sheet Rolls represent a vital chemical innovation. By replacing halogens with high-performance nitrogen-phosphorus or metal hydrate flame retardant systems (such as Aluminum Trihydroxide or Magnesium Hydroxide), these insulation rolls prevent the formation of acid gases during combustion. As a result, they yield exceptional low-smoke densities and conform strictly to global green building initiatives and rigorous safety codes, including RoHS, REACH, and the UL 94 V-0 standard.

China has become the epicenter of eco-friendly building insulation production. Our state-of-the-art facilities located in Dacheng—the celebrated capital of green-building materials—integrate chemical formulation, compounding, extrusion, and logistics.
Led by 8 dedicated chemical engineers in our R&D Department, we refine closed-cell compound formulations to yield thermal performance and fire barrier safety without halogenated additives.
Strict adherence to international validation rules, maintaining active certificates for BS 476, CE, REACH, RoHS, UL 94, and ASTM. This guarantees compliance for complex global bids.
As part of the Jinwei Group (founded in 1979), we benefit from over 40 years of continuous growth, robust raw material procurement power, and stable, cost-effective industrial manufacturing.
Our halogen-free rubber foam products are deployed across diverse sectors demanding structural safety, low toxicity, and thermal control.
High concentration of expensive electronic circuitry is highly vulnerable to corrosive acid fumes. Installing Halogen-Free insulation rolls prevents structural outgassing and guarantees that, in the event of an accidental fire, no toxic acid gases corrode delicate server hardware.
Halogen-Free insulation prevents airborne particles from circulating inside human-occupied environments. Highly chosen for public hospitals, shopping malls, airports, and luxury office buildings seeking points toward LEED green certifications.
Engineered for extreme environments, serving cryogenic setups reaching down to -200 °C, including LNG storage tanks and shipping vessels, preventing icing, structural condensation, and mechanical fatigue.
Multinational builders, EPC contractors, and HVAC distributors require continuous compliance proof when sourcing Halogen-Free insulation rolls. Our manufacturing operation satisfies these parameters through rigorous testing, factory inspections, and documentation protocols:
