1、 What is PFA connector material?
PFA connector, which is a connecting device made of perfluoroalkoxy resin (PFA), is a member of the fluoroplastic connector family. PFA materials are known for their excellent chemical resistance, heat resistance, electrical insulation, and low friction coefficient, which endow PFA joints with stable and reliable performance in harsh environments.
2、 Do you know what types of PFA connectors there are?
Direct connector: The most basic connector form, with PFA pipe interfaces of the same size at both ends, suitable for simple straight connections.
Elbow joint: Change the direction of the pipeline, with angle specifications such as 90 degrees and 45 degrees, used for laying complex pipeline systems.
Three way connector: connects PFA pipes in three directions to achieve diversion or convergence, commonly used in diversion valves or sampling points.
Quick connector: equipped with a quick lock or buckle design, convenient for quick installation and disassembly, suitable for frequent connection and disconnection situations.
Flange joint: connected by a flange plate and bolts, suitable for connections with large diameters, high pressures, or requiring additional mechanical strength.
Welding joint: It is integrated with PFA pipes through hot melt or mechanical welding to provide stronger sealing.
3、 Why do semiconductors use PFA connectors?
Chemical corrosion resistance: The semiconductor manufacturing process involves a large amount of strong acids, bases, and special chemicals. The chemical inertness of PFA joints ensures that they are not corroded when in contact with these media, ensuring the long-term stability of pipeline systems.
High purity: Semiconductor production requires extremely high levels of cleanliness, and PFA connectors are strictly controlled for impurity content during the manufacturing process, without the precipitation of harmful substances, to avoid contaminating sensitive semiconductor wafers or chemicals.
High temperature resistance: PFA joints can maintain performance in high temperature environments up to 260 ℃, adapting to process conditions such as high-temperature cleaning and diffusion in semiconductor equipment.
Electrical insulation: In semiconductor manufacturing environments involving electrochemical processes or with electrostatic risks, the excellent electrical insulation performance of PFA joints ensures safe operation.
Low precipitation: PFA joints have almost no volatile component precipitation at high temperatures, avoiding potential impact on semiconductor device performance.
