Product Overview
This high-purity PTFE sheet, measuring 3.18mm (0.125in) in thickness, delivers unmatched chemical resistance and thermal stability, making it indispensable for demanding laboratory environments. Engineered from virgin PTFE, it maintains structural integrity across a wide temperature range (-200°C to +260°C) without degradation. The non-stick surface prevents contamination, ensuring reliable performance in corrosive or adhesive-sensitive applications. Its low friction coefficient reduces wear in mechanical setups, while the inert nature eliminates reactivity with acids, solvents, or bases. The 300x300mm dimensions provide ample coverage for custom fabrication into gaskets, liners, or insulation panels. Unlike lower-grade alternatives, this sheet resists UV exposure and aging, guaranteeing long-term durability. The material’s dielectric properties also make it suitable for electrical insulation in high-voltage applications. Free from plasticizers or fillers, it meets stringent lab purity standards.
FAQs
1. Can this PTFE sheet be used for food-grade applications?
This sheet is manufactured from virgin PTFE, which is inherently food-safe and FDA-compliant for non-direct contact applications. However, verify specific regulatory requirements for your use case, as additional certifications may be needed for direct food contact.
2. What is the maximum continuous operating temperature for this sheet?
The sheet maintains its properties at continuous temperatures up to 260°C. Short-term exposure to higher temperatures (up to 300°C) is possible, but prolonged use above 260°C may accelerate degradation over time.
3. How does this compare to UHMW-PE sheets in terms of chemical resistance?
PTFE offers superior chemical resistance compared to UHMW-PE, particularly against strong acids, bases, and organic solvents. UHMW-PE may degrade or swell in harsh chemicals, whereas PTFE remains inert in nearly all laboratory reagents.
4. Is this sheet compatible with autoclaving or steam sterilization?
Yes, the sheet can withstand autoclaving at standard 121°C cycles without losing its physical or chemical properties. Ensure the sheet is dry before reuse to prevent moisture absorption in layered applications.
5. What cutting tools are recommended for fabricating custom shapes from this sheet?
Use sharp carbide-tipped blades or laser cutting for clean edges. Avoid high-speed steel tools, as PTFE’s low friction can cause clogging. For precision work, waterjet cutting is ideal to prevent heat-induced warping.
