Our service
Chunhuan Group (Zhenjiang Chunhuan Sealing Group Co., Ltd.), established in 1985, is a leading manufacturer of fluoroplastic products, chemical semiconductor linings, and new energy sealing gaskets. The company primarily focuses on the research, development, and production of fluoroplastic series sealing products (for hydrogen energy and nuclear power applications) and chemical semiconductor linings. With subsidiaries in South Korea and Shanghai, the group has also established a joint venture with South Korea's Houcheng Group for semiconductor lining equipment. Main production: PTFE products, metal seals series, steel lining anti-corrosion series, engineering plastics series,rubber products series,it is the leading enterprise in the national fluoroplastics industry. The company supplies more than 300 varieties of PTFE composite modified materials,ranging from standard composite modified materials (bronze,glass fiber,carbon,graphite,etc.) to customized solutions to meet different production needs of customers.The company provides flexible quantity and fast delivery service. The engineers have 35 years working experience in the field of PTFE,serving customers in more than 30 countries.
Q1: What is the core difference between semiconductor-grade high-purity PTFE tube and ordinary industrial-grade PTFE tube?
A1: The key differences are extremely low metal ion extraction, ultra-low particle shedding, and strict cleanliness control. We use virgin resin with special purification processes, resulting in smooth inner surfaces and organic/inorganic contaminant levels far below SEMI standards, making it suitable for sensitive processes like wafer cleaning and chemical mechanical polishing.
Q2: Is this hard tube suitable for ultrapure water (UPW) and aggressive chemicals?
A2: Yes. Pure PTFE is completely inert to UPW, hydrofluoric acid, sulfuric acid, and other common semiconductor chemicals - introducing no ionic contamination or corrosion by-products. The rigid structure also supports fluid pressure safely.
Q3: What are the working temperature and pressure ranges?
A3: Continuous service temperature is -200°C to +260°C, with short-term peaks up to +300°C. Maximum working pressure at room temperature depends on wall thickness and diameter - typically 1.0-2.0 MPa (145-290 psi). We can provide pressure ratings for specific dimensions.
Q4: How does precision molding ensure dimensional consistency and roundness?
A4: We use advanced precision molds and controlled molding processes. Outer diameter tolerance can reach ±0.05 mm, inner diameter ±0.10 mm, and roundness within 0.05 mm. Each batch is verified by CMM to ensure perfect matching with fittings, valves, and flow meters.
Q5: Can you provide custom lengths and end finishes (square cut, chamfer, flare)?
A5: Yes. We offer cut-to-length service and end treatments such as chamfering, square-cut, flaring, or flanging to facilitate connections with ferrule, flare, or flange fittings - without additional machining.
Q6: What significance does FDA certification have for semiconductor use? Does it affect purity?
A6: FDA 21 CFR 177.1550 compliance proves the material is suitable for food contact, but more importantly, it verifies resin purity and additive-free status, which aligns with high-purity requirements. This certification helps demonstrate material cleanliness history to your end-customers and also supports any potential pharmaceutical or food-grade applications.
