Suppressing contaminant residue! Introduction of thermal fusion [PFA beadless welding technology].
For medical applications such as dialysis tubing, catheters, and endoscopes. For your medical device concerns, leave it to Yowa, specializing in fluoropolymer processing.
PFA welding is a joining method that differs from welding techniques, as it integrates the objects by heating and melting the joining surfaces and applying pressure. The joint area achieves strength equivalent to that of the base material, similar to welding methods. 【Characteristics of Fluoropolymer: "C-F Bond"】 Fluoropolymers have a strong bond between carbon (C) and fluorine (F) atoms known as the "C-F bond," which results in high bond energy and a chemically inert and stable molecular structure. This "C-F bond" provides characteristics such as heat resistance, chemical resistance, and non-stick properties, demonstrating excellent properties for medical device applications! ■ Cleanliness ■ Chemical resistance ■ Heat resistance ■ Non-stick ■ Elasticity 【Solving These Concerns!】 ■ Concerned about impurities leaching from the welded area / contamination residue... → Solved with PFA welding technology that "joins" using only heat and pressure without adhesives or solvents! ■ Want to reduce costs... → Possible to reduce the number of parts and significantly decrease piping installation effort and cleaning time. ■ Want to improve liquid leakage... → Solved with "PFA welding" that smooths the welded area! *For more details, please refer to the PDF document or feel free to contact us.

basic information
■Weldable Size Corresponding wall thickness for the welded part (1mm to 3mm) For parts used in semiconductor manufacturing equipment, we recommend low ion elution grade materials such as Mitsui DuPont Fluorochemicals Co., Ltd.'s Teflon PFA 440HP-J and Daikin Industries, Ltd.'s PFA AP-211SH. ■Customer Benefits Since bonding is achieved through heat and pressure without the use of adhesives or solvents, there is no concern about impurity elution from the welded parts. It allows for the compactification of piping components. It significantly reduces the number of parts and the labor involved in piping installation, enabling cost reduction.
