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.
1. Q: What engineering plastic materials do you mainly produce?
A: We specialize in high-performance engineering plastic products such as PTFE (Polytetrafluoroethylene), PEEK (Polyetheretherketone), Nylon, and UHMW-PE (Ultra-High Molecular Weight Polyethylene).
2. Q: What are the key advantages of PTFE material?
A: PTFE offers excellent chemical resistance, high and low temperature stability (-200°C to +260°C), an extremely low friction coefficient, and outstanding insulation properties.
3. Q: Can you provide customized sealing components?
A: Yes, we support customization of seals (e.g., O-rings, gaskets, sealing rings) in various shapes, sizes, and materials based on customer drawings or technical requirements.
4. Q: Which industries are your products suitable for?
A: Our products are widely used in industries such as chemical processing, semiconductors, automotive, medical, food machinery, aerospace, and power equipment.
5. Q: Do you comply with international certification standards?
A: Our production follows the ISO 9001 quality management system, and some products are certified by FDA, RoHS, REACH, etc., meeting diverse market requirements.
6. Q: What is the minimum order quantity (MOQ)?
A: MOQ for standard products is relatively low, while custom parts depend on specifications. We strive to accommodate trial orders and small-batch requests.
7. Q: What is the lead time for delivery?
A: Standard products typically take 7-15 days, while custom parts require 2-4 weeks depending on complexity (subject to confirmation after order placement).
8. Q: How do you ensure the pressure and temperature resistance of seals?
A: We optimize material selection, conduct simulation tests, and implement strict production process controls (e.g., sintering, machining) to ensure performance compliance.
9. Q: Do you offer technical support and samples?
A: Yes, we provide free technical consultation and can send samples based on project needs (some samples may incur a nominal cost fee).
10. Q: How are products packaged and shipped?
A: We use dust-proof and moisture-proof packaging, with options for vacuum bags or wooden cases. Global logistics (air/sea/express) are supported.
