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: How to distinguish pure PTFE from filled PTFE sheets?
A: Pure PTFE is white without additives (labeled "Virgin PTFE"); filled types specify additives and may appear gray/off-white.
2. Q: Are the products certified with international standards ?
A: Pure PTFE complies with FDA . Filled types depend on formulations.
3. Q: Can I request samples?
A: Free 20×20cm samples are provided (shipping cost paid by buyer).
4. Q: What is the lead time for custom sizes/thickness?
A: Standard sizes ship in 7 days; custom orders take 15-30 days (based on complexity).
5. Q: How to verify chemical resistance data?
A: Third-party test reports.
6. Q: What is the packaging ?
A: With wooden crates, suitable for sea/air freight.
7. Q: Will harmful substances be released ?
A: Pure PTFE is stable up to 250ºC; filled types require additive verification.
8. Q: Can you deburr sheet edges or provide precision machining?
A: Standard sheets are rough-cut; CNC finishing (±0.1mm tolerance) is available at additional cost.
9. Q: What if the product fails performance tests after delivery?
A: Disputes within 15 days require third-party test reports. Confirmed issues trigger free replacement or refund.
