[Case Study] Coating that extends the lifespan of polypropylene heat-welded sheets by five times.

We will introduce examples of the use of non-stick coatings that last five times longer in release effect compared to fluoropolymer coatings.

■Concern In the heat plate welding of polypropylene sanitary products, thread pulling is likely to occur, making a non-stick (release) coating on the heat plate essential. The customer was using a PFA coating, but it deteriorated quickly, requiring the heat plate to be replaced in about a week. ■Background In this case, where repeated contact/release with components occurs at high temperatures, the effectiveness of the coating diminished rapidly. Replacing the heat plate and reprocessing the coating requires adjustments to the equipment and preparation of spare parts. A coating that excels in non-stick properties and lasts longer in high-temperature environments was needed. ■Adopted Coating FSR (Fluoro Super Release) HR-372AP ■Adoption Process and Effects Yoshida SKT prepared several samples, including the "FSR coating," which was developed with the concept of excellent release properties at high temperatures. Before the actual machine test, we confirmed the release properties of these samples at our company, and it was decided to conduct a practical test with the "FSR coating," which has a proven track record in high-temperature environments. The release effect lasted over five times longer compared to the previous PFA coating. The lifespan of the coating was excellent, and it was adopted.

basic information

■FSR (Fluoro Super Release) This is a fluorine-based release coating that combines release properties with "thermal hardness" (film hardness at high temperatures). Among fluororesins, PFA and FEP exhibit excellent release effects for molten resins, but as the usage temperature increases, the coating can become soft and may not be usable. Additionally, while PTFE has a low decrease in hardness when heated, it can be more difficult to release compared to PFA and FEP. FSR (Fluoro Super Release) achieves excellent thermal hardness that withstands use at temperatures above 200°C, in addition to release properties comparable to PFA and FEP. ■Features - Excellent release properties for molten resins - Release effect that does not diminish even under high-temperature conditions *For more details, please download the PDF or contact us.
