Ultra-Pure Containers & Gas Cylinders for Integrated Circuit Manufacturing
Overcoming critical industry bottlenecks with proprietary ultra-pure austenitic stainless steel technology. Engineered for zero-contamination, ultra-high purity (6N) electronic gas and chemical logistics.
Ultra-Pure Austenitic Stainless Steel
Manufactured using breakthrough proprietary raw materials that match or surpass leading international standards, effectively replacing imported packaging for electronic-grade chemicals.
Electropolished Surface Inner Finish
Advanced inner wall electropolishing ensures a roughness Ra ≤ 0.25 μm, eliminating particle outgassing and micro-contamination during volatile gas and liquid delivery.
Global Safety & Pressure Certifications
Fully compliant with US DOT, EU TPED, ASME Section VIII, and China TS special equipment licenses, ensuring seamless worldwide transport of hazardous chemical bulk.
Validated & Adopted by Global Semiconductor Giants
Kunshi's ultra-pure chemical packaging has successfully passed rigorous audit protocols and entered the global supply chains of leading integrated circuit foundries.
