Can you customize machining per drawings, such as cutting, flaring, or drilling?

Yes. We accept 2D (PDF/CAD) and 3D (IGES/STEP) drawings and can perform cutting, flaring, end finishing, drilling, and other secondary operations to meet precise assembly requirements for analytical instruments.

What compliance documents and batch traceability do you provide?

ROHS/REACH compliance statements, MSDS, and batch inspection reports are available. Please note that blue colored tubing is not FDA food-grade and is intended for laboratory industrial use only.

AI-Powered supplier vetting

SummaryZhenjiang Chunhuan Sealing Materials Co., Ltd. (Group) is identified as a manufacturer and trading company with its own export license, 186 employees, and more than 30 years of operating history. It produces PTFE sheets, rods, gaskets, and related plastic products, and reports ISO9001, MSDS, RoHS, REACH, and ASTM 3308 credentials. The supplier supports extensive customization and has documented inspection, corrective-action, complaint-handling, and traceability procedures. It reports inventory capability, one-month average lead times in both peak and off-season, and 20 years of export experience. However, it does not provide 3D software design services, has no available SDK, overseas warehouse, overseas showroom, overseas agent or branch, and has not participated in offline trade shows. No valid manufacturing-capacity contract with related subcontractors is reported. Financial information is referenced for 2020–2022, but the provided slices do not disclose sufficient financial results to assess...

Supplier typeThe supplier is explicitly described as both a manufacturer and trading company with its own export license. Its stated activities include manufacturing plastic products and processing machine elements and spare parts, supporting classification as a manufacturing-oriented supplier.

CertificationsThe supplier reports ISO9001, MSDS, RoHS, REACH, and ASTM 3308 credentials, while the sustainability-related certification is specified as ISO9001:2015. These stated certifications provide explicit evidence of certification holdings, although the slices do not verify their scope or current validity dates.

After-Sales capabilityThe supplier has clear procedures and followed records for handling customer complaints, as well as corrective and preventive actions. This directly supports an established after-sales issue-management process.

Production capacityThe supplier identifies itself as a manufacturer with 186 employees and established plastic-product production, reports in-stock capability, and states one-month average lead times in both peak and off-season. However, it also reports no valid manufacturing-capacity contract with related subcontractors, so the evidence demonstrates internal production capability but leaves outsourced-capacity controls as a limitation.

Customization capabilityThe supplier explicitly offers customization from samples, full customization, customization from designs, minor customization, and flexible customization. This is direct evidence of a broad customization service range.

Product Q&A

Q:Does blue PTFE capillary tubing differ in performance from natural PTFE? What does the blue color indicate?

The blue color comes from a color masterbatch, mainly for line identification - helping to quickly distinguish different fluid lines in analytical instruments and prevent misconnection. The masterbatch is added at a very low ratio and does not affect PTFE's chemical inertness, temperature range, or mechanical properties. Custom colors are available.

Q:What is the minimum inner diameter? Can it be used for micro-volume transfer?

Pressed tubes can have an ID as small as 0.1 mm, ideal for micro-liter fluid transfer; nano-liter requirements can be further discussed. Extruded and molded tubes suit larger-flow analytical lines. All dimensions are customizable.

Q:How is the chemical corrosion resistance? Which reagents can it contact?

The PTFE matrix resists almost all strong acids, strong alkalis, and organic solvents, and the blue color masterbatch does not affect its corrosion resistance. Not recommended for molten alkali metals, elemental fluor, or fluorinated media at high temperature and pressure.

Q:How do I choose among the three tube types for micro-fluid transfer?

Pressed tubes are thin-walled and supplied in rolls, best for capillary and microfluidic transfer. Extruded tubes are flexible, suitable for medium-to-long distance routing. Molded tubes are rigid, for large-diameter or high-pressure use. All dimensions can be customized.

Q:Will the tubing adsorb samples or cause cross-contamination?

The inner wall is smooth and non-porous with an extremely low friction coefficient, non-stick, and does not adsorb samples or release extractables. It is ideal for trace analysis and ultrapure liquid transfer, effectively preventing cross-contamination.
