Essential Technical Properties and Trade Terminology for ptfe stopper

Key Technical Properties of PTFE Stoppers

Understanding the technical specifications of PTFE stoppers is crucial for B2B buyers, particularly in industries requiring precision and reliability. Below are some essential properties that should be considered:

• Material Grade: PTFE (Polytetrafluoroethylene) is available in various grades, such as virgin PTFE and filled PTFE (e.g., glass-filled, carbon-filled). The choice of material grade affects the stopper’s chemical resistance, thermal stability, and mechanical strength. For instance, virgin PTFE is ideal for applications requiring high purity, while filled PTFE grades offer enhanced mechanical properties for demanding environments.

• Tolerance: This refers to the allowable variation in dimensions of the PTFE stopper. Tolerances are critical in applications where precise fit and sealing are necessary. For example, a tolerance of ±0.05 mm may be suitable for general applications, but tighter tolerances (±0.01 mm) might be required in high-precision industries like pharmaceuticals or aerospace.

• Temperature Resistance: PTFE can withstand temperatures ranging from -200°C to +260°C. Understanding the temperature range in which the stopper will operate is vital for ensuring longevity and performance. Buyers should evaluate the operating conditions of their applications to select stoppers that can maintain integrity under extreme temperatures.
