1.Core Product Positioning

Fire Retardant Expandable Graphite, which is made with natural flake graphite as its base material through a big data-optimized chemical intercalation modification process, has a core function of quickly expanding when heated to form a flame-retardant barrier. It addresses the industry pain points of high smoke toxicity and poor compatibility of traditional flame retardants, and is an environmentally friendly flame retardant ranking among the Top 3 in terms of growth rate (with a 12.8% annual growth rate, Data Source: 2025 Global Flame Retardant Materials Report) in the global flame retardant material market.

2. Core Features (Big Data-Verified Advantages)

High-Efficiency Flame Retardancy:Fire Retardant Expandable Graphite, according to data from over 1,200 combustion tests, expands 200-300 times within 10 seconds when heated to 200-300℃ (matching the decomposition temperature of most base materials), forming a dense porous carbon layer that blocks heat and oxygen transfer. This raises the flame retardant grade of the base material to UL94 V0 class and reduces the fire spread rate by over 60%.

Low Smoke and Low Toxicity: Big data monitoring shows that its combustion smoke density (Dm) is ≤50 (per GB/T 8627 standard), and the emission of toxic gases (CO, NOx) is 75% lower than that of traditional brominated flame retardants, complying with environmental regulations such as the EU REACH and China's GB 24408;

High Compatibility: Through adaptation tests with over 300 types of base materials, its dispersibility score with plastics, rubber, coatings and other base materials is ≥9.2 (on a 10-point scale), with no agglomeration and no impact on the mechanical properties of the base material (tensile strength retention rate ≥90%);

Long-Term Stability: After 8,000 hours of aging tests (60℃/95% humidity), the attenuation of expansion ratio is ≤5%, making it suitable for long-life application scenarios such as electronics and building materials (big data shows that the demand for this feature accounts for 68%).
