Frequently Asked Questions
-
Q: What is the maximum operating temperature of this sleeve?
A: The PTFE material can withstand continuous temperatures from -200°C to +260°C, making it suitable for both cryogenic and high-heat environments. -
Q: Can I get custom lengths or inner diameters?
A: Yes, we offer customization. Inner diameters from 0.5mm to 50mm are available, and lengths can be supplied in spools or cut to specific dimensions. Please contact us with your requirements. -
Q: Is this sleeve suitable for outdoor use?
A: PTFE has excellent UV resistance and weatherability, so it can be used outdoors. However, for prolonged exposure to direct sunlight, additional protection may be considered. We recommend testing for your specific application. -
Q: Does the sleeve have any certifications?
A: Our product is RoHS compliant. For other certifications (e.g., UL, VDE), they are available upon request depending on the specific order quantity and testing requirements. Please inquire for details. -
Q: How is the breakdown voltage measured?
A: Breakdown voltage is tested per ASTM D149 standards using a 1mm thick sample under controlled conditions. The 1.5kV rating is the minimum guaranteed value for the 0.2mm wall thickness. -
Q: Can the sleeve be used with high-frequency signals?
A: Yes, PTFE has low dielectric constant and low dissipation factor, making it suitable for high-frequency applications such as antenna cables and RF equipment. -
Q: What is the minimum order quantity (MOQ)?
A: For standard sizes, MOQ is typically 100 meters. For custom sizes, MOQ may vary. Small sample orders are welcome for testing. -
Q: How long does shipping take?
A: Lead time depends on order quantity. Standard orders are usually shipped within 7–15 working days. Express shipping (DHL, FedEx) is available for urgent samples.
