Among Linkason Tech’s many technological achievements, two core products—LHX-999 and LHX-HB-01—have achieved remarkable breakthroughs, successfully replacing antimony trioxide (Sb₂O₃) and bringing revolutionary changes to the plastic flame retardant industry.

LHX-999, a new type of ultra-fine powder additive inorganic flame retardant synergist independently developed by Linkason Tech, is a mineral powder material jointly researched and developed by our R&D team, Tsinghua University and relevant national academicians. Sourced from silico-magnesite mined from depths of over 600 meters underground, it is processed through advanced high-tech surface treatment and nanomodification technologies. This product boasts excellent performance, with a whiteness level exceeding 98%, an average particle size of 1.1μm, and a thermal weight loss of only 0.5‰ below 400℃, demonstrating superior thermal stability. The most significant breakthrough of LHX-999 is its ability to replace 40% to 60% of antimony trioxide in the brominated flame retardant system of modified plastics while maintaining the same flame retardant effect. Compared with antimony trioxide, LHX-999 not only exhibits better compatibility and adhesion with plastics, significantly improving the processing fluidity of materials, increasing filling capacity and enhancing reinforcement, but also reduces production costs by two-thirds—thanks to its price being only one-third that of antimony trioxide. In addition, as an inorganic powder, LHX-999 is more eco-friendly, meets SONY environmental standards, and can improve product color, making it more conducive to product appearance and coloring. It is widely applicable to various modified plastics such as PA, PBT, PP, PET, ABS, PVC and PC+ABS alloys, and has been extensively promoted and applied in the plastic industry.

LHX-HB-01, a special high-efficiency, eco-friendly flame retardant for PVC independently developed by Linkason Tech, is a composite product of organosilicon compounds and phosphorus-halogen organic compounds formed through physical and chemical crosslinking. As a dedicated flame retardant for soft PVC materials, it can completely replace antimony trioxide as the main flame retardant. The product has passed SGS testing and certification, complying with EU RoHS directives, with flame retardant performance reaching UL-94 V-0 level and minimal impact on the mechanical properties of materials. The most prominent advantage of LHX-HB-01 is its excellent smoke suppression effect, which can reduce smoke emission by 20% to 30% compared with the sole use of antimony trioxide. It is an ultra-fine free-flowing powder with exceptional thermal stability and light stability, good compatibility with PVC resin, no blooming or precipitation after addition, and high flame retardant efficiency at a low addition amount. LHX-HB-01 is widely used in the flame retardation of PVC-based products such as hoses, cable compounds, artificial leather, wallpaper, films and industrial belts, providing a safe, eco-friendly and cost-effective flame retardant solution for the PVC industry.
