About Product
Highlight
Methane Product Selling Points: Ultra-High Purity for High-Tech Industry 1. Semiconductor-Grade Purity Control (Up to 99.999%) We offer high-purity methane from 4N (99.99%) to 5N (99.999%), specifically for chemical vapor deposition (CVD) in semiconductor manufacturing and laboratory standard gas preparation. Through advanced multi-stage purification technology, we strictly control non-methane total hydrocarbons (NMHC) and moisture, ensuring high process yield. 2. Vertically Integrated Hardware Safety Methane is a flammable compressed gas. Leveraging our cylinder and valve manufacturing capabilities at our factory in mainland China, we provide specialized cylinders with passivated inner surfaces and high-tightness explosion-proof valves (such as CGA-350), eliminating the risk of secondary gas contamination and leakage from the container source. 3. Flexible International Supply Solutions Utilizing our presence in three major industrial hubs in Asia

FAQs
Can your cylinder connections be customized?
Yes. We can install valves that comply with global standards, such as CGA-350 (North American standard), DIN-477 No.1 (European standard), or BS-341 No.4. Please inform us of your pressure regulator connection type when requesting a quote.
Why choose to purchase from your multinational factories?
We have production bases in Taiwan, mainland China, and India. This not only mitigates potential logistics disruptions in specific regions but also allows you to choose the export country based on current trade policies, maximizing savings on logistics costs and customs duties.
How do you ensure the safe transportation of flammable gases?
Methane is a Class 2.1 hazardous material. We use high-pressure seamless steel cylinders that comply with DOT-3AA, TPED, or ISO 9809 standards. The packaging is reinforced with impact-resistant steel caps and thickened pallets, and we provide a complete **MSDS (Material Safety Data Sheet)** for safe handling instructions.
What grades of methane do you offer?
We primarily offer two grades:
4.0 Grade (99.99%): Used for industrial combustion testing, syngas production, and basic research and development.
5.0 Grade (99.999%): Ultra-high purity electronic grade, specifically for semiconductor CVD processes, silicon carbide (SiC) epitaxial growth, and precision instrument calibration.
