What is PFA Tube? What is a high purity PFA tube?
PFA pipe is through the PFA resin raw material extrusion molding, injection molding of the pipe, in general, we are talking about extrusion molding of the pipe. It has excellent heat resistance, chemical resistance and electrical properties, and can be formed by various melting resin forming methods. Excellent heat resistance (mechanical strength maintained in a wide range of temperatures from -80 ° C to 260 ° C), excellent chemical resistance (almost inert to all chemicals);
Excellent electrical characteristics (low dielectric constant and low dielectric loss factor at high frequencies, insulation);
Very excellent flame retardancy (limiting oxygen index 95Vol%, UL94V-0).
PFA tubes produced by importing Japanese Daikin 231SH, American Chemours/ DuPont 451HP, DuPont 951HP and other brands of high purity pfa raw materials are generally called high purity PFA tubes.
What is SEMI F57 certification?
SEMI F57 Specification for polymer materials and components used in ultra-pure water and liquid chemical delivery systems. The standard specifies minimum performance requirements for ultra-high purity (UHP) polymer materials and components for transporting ultra-pure water (UPW) in UPW distribution systems. Mainly for the performance requirements and verification of polymer materials and components.
The International Semiconductor Industry Association (SEMI) provides a set of environmental, safety and health guidelines for semiconductor process equipment that apply to all equipment used in chip manufacturing, measurement, assembly and testing. The use of ultra-pure water and ultra-pure chemicals used in semiconductor advanced process technology is increasing, the selection of materials is becoming more and more important in semiconductor wet process, and the purity requirements for fluoropolymers are also getting higher and higher. SEMI F57 standard puts forward requirements and effective suggestions for the selection of high polymer materials and components, production process, product structure design and other aspects in UHP liquid chemical delivery system (LCDS).
SEMI F57 standard applies to products
1, semiconductor ultra-pure water. Polymer materials, components and process equipment for liquid chemical delivery systems
2, pipes, accessories, valves, filter housing, pressure sensor, flow meter, meter, calibrator.
