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: Is your PTFE tube made from virgin material or recycled resin? How do you ensure purity?
A1: We use 100% virgin PTFE resin without any regrind or additives. Each batch comes with the original material data sheet, and third-party purity test reports are available upon request to guarantee batch-to-batch consistency.
Q2: Is this tube suitable for food or pharmaceutical applications? Can you provide FDA documentation?
A2: Yes. Our virgin PTFE complies with FDA 21 CFR 177.1550 for food contact and pharmaceutical use. Each batch is supplied with a FDA declaration of compliance, along with MSDS and ROHS/REACH certificates.
Q3: Can you machine non-circular sections (e.g., oval, square) or tubes with flanged ends?
A3: Standard tubes are round, but we can perform secondary machining based on your 2D drawings (PDF/CAD) or 3D models (IGES/STEP) to produce shaped tubes, stepped bores, flanged or flared ends - all without the need for dedicated molds.
Q4: Can the roundness and straightness meet automatic assembly line requirements?
A4: Yes. We can control roundness (typically ≤ 0.5% of OD) and straightness (≤ 0.5 mm per meter). For tight automated insertion, tighter custom standards can be set - please specify when ordering.
Q5: Do you support small-batch trial production, and what technical documents are needed?
A5: Yes, small-batch samples are welcome. Simply provide your required ID, OD, length, tolerance, and any special end finishing needs. For complex shapes, please supply CAD or STEP files.
Q6: Is this tube suitable for ultrapure water or electronic-grade chemicals? Is there any risk of ion leaching?
A6: Virgin PTFE is inherently pure with extremely low extractables, making it common in semiconductor and photovoltaic high-purity fluid transfer. However, we recommend performing leaching tests based on your specific fluid and temperature - we can supply compatibility reference data to assist.
