Yanxatech System Industries Limited (hereinafter referred to as YANXA) is a premier, rapidly expanding supplier specializing in advanced chemical compounds, industrial gases, and micro-powder alloys in China. Initiated as a fledgling, focus-driven small business unit in 2008, YANXA was powered by a vision to develop highly stable international supply chains in the chemical and mechanical sectors.
Through our team’s dedicated and persistent manufacturing optimization, as well as the deep support of our global partners, YANXA has evolved into an ISO9001:2008 certified enterprise. We deliver flawless specialty products that meet strict technical, commercial, and environmental requirements.
"Cooperating with China's leading research institutes, YANXA continuously redefines purity boundaries for specialty gases like Carbon Tetrafluoride (R 14), advanced liquid rubbers, and complex metallic powders."
Achieving 99.999% (5N) to 99.9999% (6N) purity levels in R-14 (Carbon Tetrafluoride) through multi-stage low-temperature distillation. This eliminates trace nitrogen, oxygen, and moisture, preventing wafer contamination in semiconductor dry etching.
Developing new catalytic systems to synthesize CF4/R 14 directly from fluorine alternatives, lowering direct greenhouse gas emission during manufacturing by over 35% and improving raw material atom economy.
Implementing smart, telemetry-enabled chemical packaging solutions that monitor internal pressure, temperature, and leakage in real-time, ensuring safe ocean logistics for global electronics manufacturers.
Our ultra-pure R-14 (Carbon Tetrafluoride) serves as the primary plasma etchant for silicon dioxide and silicon nitride thin films. Its chemical stability ensures atomic-scale precision in the latest sub-7nm node technologies, enabling high-performance chip production.
Through our premium Atomized Spherical Aluminum Magnesium Alloy Powder and Flake Zn-Al coatings, we supply automotive and aerospace sectors with high-durability, corrosion-resistant, lightweight metal additives necessary for high-stress applications.
Supplying specialized liquid rubbers (HTBS, MLPB, L-XNBR) to global industrial elastomer producers. These compounds provide exceptional impact resistance, low-temperature flexibility, and critical adhesion improvements for heavy-duty sealing profiles.
Our manufacturing centers employ the latest Industry 4.0 automated control loops. In our chemical synthesis plants, temperature, pressure, and catalyst feeding are monitored by cloud-linked DCS systems to eliminate human error.
By coupling advanced manufacturing plants with reliable logistics networks at coastal shipping ports, we offer a highly resilient supply chain that handles volatile market shifts smoothly. This ensures that wholesale orders of R 14, nitrates, and metal powders are fulfilled on time, regardless of global trade conditions.

All hazardous chemicals are registered and shipped with fully compliant Global Harmonized System (GHS) Safety Data Sheets (SDS). We also provide REACH documentation for European markets, eliminating clearance bottlenecks.
We work with international logistics providers certified in handling Class 2 (Gases), Class 4 (Flammable Solids), and Class 9 (Miscellaneous Dangerous Goods). Every container uses certified pressure vessels or multi-layered drums.
Our dedicated regulatory department handles complex customs protocols. We prepare certificates of origin, chemical analysis sheets (COA), export licenses, and customs documentation for seamless arrival at your port.
Product Characteristics: Formaldehyde is a colorless liquid, easily polymerized, and readily soluble in water, alcohol, and ether. It is rapidly oxidized to formic acid in air, acting as a strong reducing agent. Its boiling point is -19°C, freezing point -118°C, and relative density to air is 1.067. Commercially, it is supplied in liquid form as formalin, a 37-50% formaldehyde solution with a small amount of methanol added as a polymerization inhibitor. The solution is milky white and has a foul odor. Formalin readily vaporizes, releasing formaldehyde gas. Its boiling point is 96°C, relative density is 0.815/-20°C, and flash point is 55°C.
Product Overview: Hexamethylenetetramine, also known as hexamine or HMTA, is a white crystalline powder produced by the condensation reaction of formaldehyde and ammonia. It is a versatile organic chemical intermediate widely used in industrial manufacturing, pharmaceutical synthesis, rubber processing, and analytical chemistry.
Product Features: A white powdery solid with a flammable odor of formaldehyde. It is a linear polymer of formaldehyde with no fixed melting point.

Confirm the purity grade required. Electronic Grade R 14 (purity ≥99.999%) is mandatory for semiconductor wafer dry-etching. Industrial/Refrigerant grade R-14 (purity ≥99.9%) is suitable for metal treatment, polymer blowing, or ultra-low temperature HVAC applications.
Always request a comprehensive Certificate of Analysis (COA) containing detailed gas chromatography data. For R 14, trace carbon monoxide (CO), carbon dioxide (CO2), moisture (H2O), and sulfur compounds must be lower than 1 ppm in electronic manufacturing.
Identify local pressure vessel regulatory markings (such as DOT-3AA for the United States, TC-3ASM for Canada, or EN/ISO cylinder markings for the European Union) and valve thread patterns (like CGA 580 or DISS 632) to prevent connection issues.
