1. What is the thermal deflection temperature of PFA tube?
PFA (perfluoroalkoxy resin) tubing has a wide range of long-term service temperatures, and its heat deflection temperature is typically higher than that of most plastic tubing. The heat deflection temperature of PFA material is generally about 260 °C, below which the PFA tube can maintain stable physical properties and dimensional stability, and significant deformation may occur beyond this temperature.
2. What is the PFA hot melt temperature?
PFA has a higher melt or processing temperature, typically between 350 and 400, depending on the grade and manufacturer's process requirements. Within this temperature range, PFA materials can be efficiently melt processed, such as extrusion, injection molding, etc., but need to be tightly controlled to avoid material decomposition or degradation of properties.
3. Can PFA tubes be bent?
PFA tubing can be bent appropriately due to its excellent flexibility and ductility. Because PFA material has good low-temperature toughness and can still maintain a certain degree of flexibility at high temperature, in practical applications, PFA pipes can not only be cold-formed at room temperature, but also can be used to make bellows or pipe systems with a certain radius of curvature. PFA tubing is able to accommodate a wide range of complex layouts and space constraints during design and installation, as long as the bend radius is large enough to prevent internal stress concentrations and potential damage due to excessive bending.
However, despite the good bending properties of PFA tubing, the appropriate technical specifications should be followed during bending operations to ensure that the wall structure is not damaged, and to consider the environment in which it will be used after bending, such as the possibility of lasting deformation at high temperatures. For particularly complex wiring or connection needs, specialized tools or methods may be required to complete safe and efficient bending jobs. At the same time, PFA tubing may undergo greater elastic deformation when subjected to greater external pressure than metal tubing or other rigid materials, which also needs to be considered in the design.
