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 paste extrusion / ram extrusion, and how does it differ from traditional PTFE hose processes?
A1: Paste extrusion mixes PTFE fine powder with a lubricant, then forces the mixture through a ram extruder under high pressure, followed by drying and sintering. Compared to skiving or molding, ram-extruded hoses have smoother inner walls, higher density, continuous length, and seamless construction.
Q2: Can the hose length be customized? What is the maximum continuous length?
A2: The paste extrusion process allows continuous production. A single hose can exceed 100 meters, depending on diameter and wall thickness. Cut-to-length services (e.g., 1 m, 5 m, 10 m) are also available.
Q3: What is the continuous operating temperature range of the hose?
A3: The continuous working temperature range is -200°C to +260°C. Short-term exposure to higher temperatures (e.g., 300°C) is possible but should be evaluated per application.
Q4: Is the hose food-grade certified? Can it be used for drinking water or food transfer?
A4: Yes. The PTFE material complies with FDA 21 CFR 177.1550 and can also meet NSF or RoHS requirements. It is suitable for food sauces, beverages, drinking water, and pharmaceutical purified water systems.
Q5: Is the inner surface smooth? Does it adsorb or retain media?
A5: The paste extrusion process creates a mirror-smooth inner surface with an extremely low friction coefficient. Media hardly adheres or remains, making it ideal for high-purity or crystallizing media and easy to clean.
Q6: Can this hose be used for steam tracing lines or high-temperature condensate drainage?
A7: Yes. PTFE is heat-resistant and non-hydrolyzing, suitable as a liner for steam tracing lines or for short-distance high-temperature condensate transfer.
Q7: What is the bending radius of the hose? How flexible is it?
A8: Pure PTFE ram-extruded hose has moderate flexibility. The minimum bending radius is typically 10-15 times the outer diameter. For higher flexibility, a convoluted or spiral-reinforced structure can be considered.
Q8: Is the hose electrically insulating? Can it be used as a protective electrical sleeve?
A9: PTFE offers excellent dielectric strength and volume resistivity, making it an outstanding electrical insulator. It can be used as a wire or cable jacket in high-temperature environments.
