Innovative fire resistance technology at Shuanghong

Polyester yarns have been subjected to several flame retardant treatments. In our quest for safety and environmental sustainability, we have adopted numerous cutting-edge technologies. The following are just some of the most important innovations that distinguish us:

Utilization of Modern Materials

ZIFs (Zeolitic Imidazolate Frameworks): ZIFs are a combination of traditional zeolites and Metal-Organic Frameworks (MOFs). They are derived from transition metals together with imidazole-containing organic ligands which self-assemble into ZIF crystals. Synthesis is simplified in ZIF materials besides being stable with high catalytic activity. These materials can greatly improve the flame-resistance ability of polyester yarns while preserving their mechanical properties.

POSS (Polyhedral Oligomeric Silsesquioxanes): POSS is a special silicon-based flame retardant that has both organic as well as inorganic hybrid structures. Apart from improving fire retardancy, it also enhances the processing and mechanical characteristics of these fibers. As an additive for increasing polyesters’ thermal stability and fire retardancy; these polymers feature unique cage-like or nanostructures composed of POSS.

Graphene (GNS): Graphene and its related forms like graphene oxide (GO) are two-dimensional nanomaterials possessing good flame-retardation ability.

Alkyl phosphate salts are present in the mixture of flame retardants while possessing high thermal stability and good flame retardant effect. They are also considered expensive and may not always provide ideal mechanical properties even when used alone. So, to combine this with other addictive such as nanomaterials or inorganic flame retardants, we have created synergistic systems that include alkyl phosphinate salts. For example, a combination of AlPi and TGIC (tris(glycidyl isocyanurate)) in polyamide 6 (PA6) has been shown to achieve UL-94 V-0 rating with an LOI (Limiting Oxygen Index) of 30.3% when the total addition is 11% and the ratio of AlPi to TGIC is 97:3.

Ammonium Polyphosphate (APP), Aluminum Hypophosphite (AHP), and Melamine Cyanurate (MCA): We also employ APP, AHP, and MCA as a synergistic system for PP. This means that its effectiveness increases if more than one agents are used together instead of using them single-handedly. With ratios m(APP):m(AHP):m(MCA) = 4:1:1, total addition equals 30%. The LOI obtained from this combination was around 33% and a UL-94 V-0 rating was observed.

Macromolecular Flame Retardants

DOPO-PCP (6-[4-(N-Phenylamino-DOPO-Methylene)Phenoxy]Cyclotriphosphazene): This is a novel inorganic-organic hybrid macromolecular flame retardant prepared using chemical reactions. It contains high contents of flame retardant elements and has good compatibility with high molecular weight materials. DOPO-PCP has been used successfully to flame retard DGEBA (diglycidyl ether of bisphenol A).

HAPN (Hybrid Aromatic Phosphorus Nitrogen): It is a type of new macromolecular intumescent flame-retardant that can quench free radicals. Its combination with APP allows improved fire resistance properties to be achieved in polypropylene (PP).

Environmental Considerations

Non-Toxic and Eco-Friendly Materials: Shuanghong uses only non-toxic flame retardants that do not emit toxic fumes during processing or the life cycle of the product, making them safe for both users and the environment.

Sustainable Practices: Our manufacturing processes are designed in such a way as to minimize waste generation as well as reduce energy consumption. We make sure that treated yarns are recyclable thereby reducing their environmental impact even more.

Impact on Yarn Performance

Improved Safety: The introduction of fire-resistant chemicals through this treatment has significantly reduced flammability levels hence making them suitable for different applications including those whose safety regulations are very strict.

Enhanced Performance: However, this does not affect the strength or hand feel of the yarns thereby maintaining high quality and performance in the final product.

Wider Application: Our treated yarns can be used in a broader range of applications, including public spaces, transportation, and industrial settings, due to improved safety and performance.

Shuanghong Company’s innovative flame retardant technologies are a testament to our commitment to safety, quality, and environmental responsibility. We make sure that our polyester yarns remain not only flame retardant but also maintain their mechanical and performance properties through the application of advanced materials as well as synergistic systems. Further, our emphasis on eco-friendly resources and sustainable procedures cements our leadership in the market.

Comparison between traditional flame retardants and environmentally friendly flame retardants

Traditional flame retardants, especially halogen flame retardants, are highly efficient and require low dosage in flame retardant treatments, but they pose significant environmental and safety issues. During combustion, a large amount of toxic and corrosive gases, such as hydrogen halides, are released, which not only pollute the environment but also pose a potential threat to human health. In addition, traditional flame retardants produce a large amount of smoke when burning, which aggravates the hazards of fire, has a great impact on the mechanical properties of the material, and has poor thermal stability. Although its initial cost is low, in the long run, the costs brought about by environmental governance and health issues are high, and it is restricted by regulations in many countries, making market access difficult.

In contrast, environmentally friendly flame retardants show significant advantages in many aspects. During the flame retardant treatment process, the environmentally friendly flame retardant is non-toxic and harmless, and does not produce harmful gases when burned, which meets environmental protection requirements. They are low in smoke and toxicity, safer when burned, and suitable for fields with high safety requirements such as electronic appliances.

Environmentally friendly flame retardants have little effect on the mechanical properties of materials and good thermal stability while maintaining good flame retardant effects. Although the initial cost is high, the long-term use cost is low, and the product value and competitiveness are high. Environmentally friendly flame retardants have a wide range of applications, covering multiple industries such as construction, electronics, and automobiles. They comply with strict environmental regulations and are easier to obtain market access and certification.

in conclusion

In summary, environmentally friendly flame retardants are superior to traditional flame retardants in terms of environmental protection, safety, performance and economy. Especially in modern society, where environmental protection and sustainable development are of great concern, environmentally friendly flame retardants are widely used. The application prospects are broad. By adopting advanced environmentally friendly flame retardant technology, Shuanghong Company has not only improved the safety and performance of its products, but also established a good environmental image in the industry.
