In fluororesin sheet lining processing, there are two methods: "adhesive lining," where sheets made of PTFE or PFA are processed to allow one side to be bonded using a special method and then adhered to the substrate with adhesive, and "loose lining," a processing method like lining pipes where the liner is not bonded to the substrate. Sheet lining can process thicker linings compared to many other fluororesin lining methods. This results in excellent corrosion resistance among various fluororesin linings. On the other hand, the adhesion strength with the substrate depends on the adhesive's bonding power, so it generally does not accommodate use in negative pressure environments. Negative pressure applications can be addressed with other methods such as baked lining or roto-lining. *You can download a document summarizing the details of the lining. Please make use of it. *For more information, please click on "PDF Download" or feel free to contact us.

PTFE lining is characterized by the use of pre-formed PTFE sheets and pipes, and it is also referred to as PTFE sheet lining. Since PTFE has non-stick properties, it cannot usually be adhered with adhesives. Lining sheets are used that have been processed to allow adhesion on one side during or after molding (adhesive lining). ■ Advantages of PTFE Lining By using molded sheets, it is possible to create thickness, making it suitable for use in more demanding environments. Additionally, it is characterized by excellent gas permeability. ■ Disadvantages of PTFE Lining PTFE lining is difficult with baked coatings, so the usable temperature depends on the heat resistance of the adhesive. Furthermore, its use in negative pressure environments is generally not recommended. Yoshida SKT offers lining sheet sales and lining construction services. *For more details on lining, please check the materials or feel free to contact us.

PFA lining offers a variety of construction methods compared to PTFE lining and is characterized by its ability to be processed into various substrate shapes. ■Advantages of PFA Lining PFA lining can be processed mainly through three methods: "sheet lining," "electrostatic coating (baked coating)," and "rotational molding (rotolining)." Therefore, it is possible to create linings that accommodate various substrate shapes. ■Disadvantages of PFA Lining In some usage conditions, the lifespan may be shorter compared to PTFE sheet lining. It is necessary to choose carefully, taking into account temperature conditions, pressure conditions, and the type and concentration of the contact chemicals. Please refer to the materials for the characteristics, advantages, and disadvantages of each processing method. *If you have any questions about fluoropolymer lining, please feel free to contact us.

ETFE lining is a type of fluoropolymer lining that is primarily processed using techniques such as powder coating and rotational molding (rotolining). ■ Advantages of ETFE Lining ETFE has a low melting point and excellent processability, allowing for thick film processing on various shapes of substrates. ■ Disadvantages of ETFE Lining On the other hand, because its molecular structure contains hydrogen (H), it has inferior heat resistance and chemical resistance compared to PTFE. The choice of materials and methods for lining needs to be tailored to the application, environment, and substrate shape. Yoshida SKT offers powder coating and rotational molding (rotolining) for ETFE lining. *Please feel free to contact us when considering lining options.

【Fluororesin Sheet Lining Processing】 Fluororesin sheet lining involves adhering a fluororesin sheet to a substrate using adhesives, and welding the seams with fluororesin to cover the substrate. (Adhesive lining) ■ Features of Fluororesin Sheet Lining Fluororesin is one of the resin materials that excels in chemical resistance and heat resistance. Fluororesin sheet lining is characterized by its ability to achieve thick lining processing, making it highly resistant to corrosion among various fluororesin lining methods. On the other hand, since the process includes welding the seams of the sheets, there may be steps on the lining surface. ■ Overview of Processing Fluororesin sheets, pre-cut to match the shape of the substrate, are adhered to the substrate, and the seams are welded. ■ Processing Thickness 2 to 4 mm *We have prepared materials summarizing comparisons and details of fluororesin lining. Please feel free to utilize them.

【Fluororesin Sheet Lining Processing Procedure】 ■ Acceptance The base material (cylinder body) is checked against the order form, drawings, specifications, etc., to confirm whether it has a suitable shape for lining. ■ Sandblasting The lining surface is sandblasted to remove rust, dirt, etc., and is roughened to a texture suitable for lining. ■ Sheet Cutting The lining sheet material is cut based on the welding development drawing. ■ Attachment Adhesive is applied to the lining area of the base material (cylinder body) and the back side of the lining material, and they are adhered together. ■ Edge Preparation The welding joint areas, left and right, and depth are evenly prepared, and excess adhesive in the gaps is removed. ■ Welding Butt welding Tape welding ■ Process Inspection A pinhole test is conducted after butt welding. A pinhole test is conducted after tape welding. *You can download materials summarizing the details of the lining. Please make use of them.

【Fluororesin Lining Processing Steps】 1. Acceptance We will inspect the substrate. If there are any issues that may affect the thick film processing, we may request corrections. 2. Degreasing Treatment [Preheating] The substrate is heated in a furnace to thermally decompose oils and dirt at a temperature higher than the firing temperature. 3. Surface Preparation [Blasting] The processing surface is blasted to remove rust, dirt, etc., and to create a rough surface. 4. Primer Coating A primer is applied to enhance the adhesion between the substrate and the fluororesin. 5. Firing The primer is cured in the furnace. 6. Coating [Powder Coating] Fluororesin powder is applied using electrostatic or special coating equipment. 7. Firing The fluororesin is heated to melt the resin and form a coating. *The size of the substrate that can be processed is determined by the size of the furnace. 8. Repetition Steps (6) to (7) are repeated to increase the coating thickness until the desired functionality is achieved. 9. Inspection We will inspect whether the processing meets the specifications and agreements. *The process is almost the same as fluororesin coating. *Please download the document summarizing the details of the lining for your reference.

■Concerns to be resolved and goals to be achieved We received an inquiry about wanting to apply an anti-static coating to thin aluminum parts used in semiconductor equipment. The conventional fluorine-based anti-static coatings required high firing temperatures, which raised concerns about distortion in the aluminum parts. We were looking for a coating that could provide anti-static properties and was less prone to distortion even for thin aluminum parts. ■Coating adopted Saflon LF+ ■Effects achieved Among the Saflon series, Saflon LF+ has a low minimum firing temperature of below 100°C, which is expected to reduce distortion caused by firing, so we proposed it. We confirmed the provision of anti-static properties and resolution of distortion issues through tests and prototypes, leading to its adoption for product coating. The newly developed Saflon LF+ is an anti-static fluororesin coating that can accommodate various environments and applications of our customers.

ETFE coating is a type of fluoropolymer coating that is primarily processed using techniques such as powder coating and rotational molding. ■ What is ETFE Coating? ETFE is a type of fluoropolymer, specifically a copolymer of tetrafluoroethylene and ethylene. It is mainly processed using powder coating technology and is considered a relatively thick coating among fluoropolymer coatings. Therefore, it is commonly referred to as ETFE lining. ■ Advantages of ETFE Coating ETFE has a low melting point and excellent processability, allowing for thick coatings on various substrate shapes. ■ Disadvantages of ETFE Coating On the other hand, because its molecular structure contains hydrogen (H), its heat resistance and chemical resistance are inferior compared to PTFE.
