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: Is this PTFE rod truly FDA-compliant for food contact?
A1: Yes. The pure PTFE (unfilled) grade meets FDA 21 CFR 177.1550 requirements and can be directly used for food-processing equipment spare parts such as seals, guide rings, wear pads, rollers, and bushings. Please note that if fillers (e.g., glass fiber, carbon) are added on request, the filled version is no longer FDA-compliant and is limited to industrial use.
Q2: You offer both molded and extruded processes. What is the difference, and which should I choose?
A2: Extruded rods suit standard diameters from 5 to 350 mm with continuous length, lower cost, and are ideal for most food-processing spare parts. Molded rods are better for large diameters, thick walls, or applications requiring higher density and creep resistance, with better dimensional stability. If unsure, we can recommend the right process based on your part shape and load conditions.
Q3: Can all diameters from 5 to 350 mm be customized in length? What is the minimum order quantity?
A3: Yes, length is fully customizable. Standard lengths can be 1000 mm, 2000 mm, or longer, and we can cut short segments per your part size. MOQ is flexible, typically starting from 5-10 kg per size, depending on diameter.
Q4: What does "filler reinforcement on request" mean? Can filled material still be used for food contact?
A4: We can add glass fiber, carbon fiber, graphite, MoS2, etc., to improve compressive strength, rigidity, wear resistance, or thermal conductivity. However, filled materials do not meet FDA food-contact requirements and are only for non-food industrial parts. If you need food-grade, please choose the pure unfilled PTFE grade.
Q5: Is this rod easy to machine? Can you turn, mill, or drill it according to my drawings?
A5: Both pure and filled PTFE offer excellent machinability. We accept PDF/CAD 2D drawings and IGES/STEP 3D models for turning, milling, drilling, tapping, and slotting, delivering finished spare parts directly to reduce your processing steps.
Q6: What is chemical resistance? Which food media can it contact?
A6: Pure PTFE resists virtually all strong acids, bases, organic solvents, and food media, including oils, water, dairy, beverages, and cleaning agents. It does not leach contaminants into food, making it ideal for corrosive or high-temperature environments in food processing.
Q7: What spare parts in food-processing equipment are typically made from this rod?
A7: Common applications include pump and valve seal rings, valve seats, guide sleeves, bearings, rollers, wear strips, gaskets, diaphragm supports, and conveyor line bushings. It can also be machined into custom shapes to replace metal parts, avoiding contamination and corrosion.
Q8: How do you ensure consistent dimensions and performance for each batch of rod?
A8: We use controlled resin raw materials and standardized molding or extrusion processes. Each batch is tested for density, hardness, tensile strength, and critical dimensions. Retained samples and lot traceability records ensure reliable long-term operation of food-processing equipment.
Q9: If I need to make non-standard parts, can you provide technical advice?
A9: Yes. Our engineering team can assist with wall thickness, tolerances, filler selection, and machining feasibility to help optimize your part design, avoid cracking or deformation, and shorten development time.
