FAQ

Q1: What is the difference between molded sheet and skived sheet? How do I choose between them?
A: Molded sheets are formed under high temperature and pressure in a mold, resulting in a dense internal structure. They are ideal for thicker specifications (typically above 10mm) or applications requiring high material uniformity. Skived sheets are produced by continuously peeling a molded billet, offering excellent surface finish and tight thickness tolerances. They are best suited for thin sheets in the 1-10mm range and large dimensions. Choose molded sheet for thick sections or higher mechanical strength; choose skived sheet for thin walls, large formats, and superior surface flatness.

Q2: What thickness range is available? Can nonstandard thicknesses be customized?
A: Standard thickness ranges from 1mm to 100mm. The molded process primarily covers medium to thick sheets of 10-100mm, while the skived process focuses on thin sheets of 1-10mm. We support custom thicknesses based on customer drawings, and post machining can achieve thickness tolerances within ±0.05mm.

Q3: Can PTFE sheets be filled or reinforced to improve performance? What fillers are available?
A: Yes. Virgin PTFE is suitable for basic applications requiring corrosion resistance or insulation. To enhance wear resistance, creep resistance, or thermal conductivity, we offer filled modifications. Common fillers include glass fiber, carbon fiber, graphite, molybdenum disulfide, bronze powder, and polyimide. We can recommend the optimal formulation based on your operating conditions.

Q4: What is your post machining capability? Can you supply finished parts with holes, slots, or custom shapes?
A: We are equipped with CNC machining centers, milling machines, and precision cutting equipment. We can perform cutting, drilling, slotting, turning, chamfering, and other processes to deliver finished parts directly, eliminating secondary processing for our customers while ensuring tight dimensional accuracy and short lead times.

Q5: What is the temperature range of PTFE sheets? Can they be used in high temperature steam environments over long periods?
A: PTFE typically operates from -180°C to +260°C and remains stable in harsh conditions such as high temperature steam, strong acids, and alkalis. However, material degradation may occur above 260°C. Additionally, skived sheets may exhibit slightly lower dimensional stability under prolonged hightemperature exposure compared to molded sheets. We can evaluate your specific application to provide technical recommendations.

Q6: What flatness and tolerance levels can be achieved?
A: Skived sheets offer excellent surface flatness with thickness tolerances typically within ±0.05-0.10mm. Molded sheets, due to their greater thickness, generally have tolerances of ±5-10% of the nominal thickness. We can perform precision machining on critical dimensions to achieve flatness and parallelism suitable for precision assembly requirements.

Q7: Does virgin PTFE meet food contact or medical grade requirements?
A: Virgin PTFE is inherently biocompatible and nontoxic. It complies with FDA and RoHS standards. For applications in the food, pharmaceutical, or medical industries, we can provide material certifications and thirdparty test reports to confirm raw material purity and regulatory compliance.

Q8: What are the maximum sheet dimensions available? Are there length or width limitations?
A: Skived sheets, produced by continuous peeling, can reach widths up to 1200mm with customizable lengths of several meters. Molded sheets are typically limited to individual mold sizes, commonly within 500×500mm, but larger dimensions can be achieved by custom molds or joining techniques to meet specific requirements.

Q9: What is the minimum order quantity? What is the typical lead time for customized products?
A: There is no minimum order quantity for standard thickness sheets; small trial quantities are welcome. For custom thicknesses or machined parts, the MOQ is flexible based on the specific requirements. Standard sheet production typically takes 3-7 days, while machined parts require about 7-15 days depending on complexity. Rush orders can be accommodated with priority scheduling.

Q10: How do you ensure batchtobatch quality consistency? What test reports are provided?
A: We implement a full inspection process from raw material receiving to final product shipment. Key parameters such as density, tensile strength, and elongation at break are recorded for each batch. We can supply factory test reports, material certificates, RoHS/REACH declarations, and arrange thirdparty testing upon request to ensure consistent quality.
