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 this white PTFE capillary tube meet FDA, ROHS, and REACH certifications? Can it be used for food or medical contact?
A:
It is made from pure PTFE (no fillers), compliant with FDA 21 CFR 177.1550 for food contact, and meets ROHS and REACH regulations. MSDS documentation is available. It is suitable for food processing, pharmaceutical, and laboratory precision fluid delivery. For medical-grade certification, please specify in advance so we can provide the appropriate compliance statement.
Q:I need a capillary tube with an extremely small inner diameter, such as 0.1 mm. Can you produce it?
A:
Yes. Our Press Tube series can produce capillary tubes with OD 0.2-25 mm and ID 0.1-23 mm, with a minimum ID of 0.1 mm, supplied in rolls. Dimensions are fully customizable to meet precision fluid control requirements.
Q:Among extruded, molded, and press tubes, how do I choose the right type for laboratory capillary applications?
A:
Press tubes are ideal for extremely small ID, thin-wall precision capillaries such as microfluidics or micro-sampling. Extruded tubes (OD 13-213 mm) suit medium diameters and longer lengths (500-4000 mm) for continuous delivery. Molded tubes (OD 30-1323 mm) are for large diameters, thick walls, or high-pressure situations. Choose based on flow rate, pressure, length, and installation space.
Q:Can it resist strong acids, bases, and organic solvents? Will it release extractables that contaminate reagents?
A:
PTFE resists almost all strong acids, strong bases, and organic solvents, with no extractables and non-stick properties. It is therefore ideal for corrosive liquid delivery in laboratories without contaminating reagents or samples.
Q:How smooth is the inner wall? Does it affect delivery precision and residual volume for micro-fluid handling?
A:
The inner wall is extremely smooth with a very low friction coefficient, so liquid does not easily adhere. For micro-fluid delivery, it effectively reduces wall cling and dead volume, improving metering accuracy. For even lower retention, custom inner-wall treatments are available.
