■Difference Between Teflon and Fluoropolymer Teflon is a trademark of Chemours and is a brand name for fluoropolymers. Fluoropolymers include various types such as PTFE, FEP, PFA, and ETFE, but Teflon is a trademark for some of these. Teflon is a registered trademark of DuPont, represented by the 'R mark', while Chemours uses the 'TM mark'. Teflon-coated frying pans have popularized the term "Teflon coating" in society. Nowadays, the name Teflon is more well-known than the term fluoropolymer. Other chemical manufacturers also produce fluoropolymers, which are marketed under different product names. Industrial Teflon processing can be done at factories that have entered into licensing agreements with Chemours (DuPont). Yoshida SKT signed a contract with DuPont in January 1968 to become a Licensed Industrial Applicator (designated factory for industrial coatings).

This is an introduction to a coating case for cutting tools used to dispose of packages with adhesive. ■ Background of Surface Treatment Consideration In the device that extracts products from packages, a mechanism was needed to automatically cut adhesive packages into smaller pieces for disposal. ■ What We Wanted to Achieve The device operates unmanned, and human intervention is only required when the dust box is full of finely cut packages. Therefore, it was necessary to prevent the adhesive from adhering to the cutting blade and to operate without maintenance. ■ Conditions for Choosing Treatment Initially, tests were conducted using fluororesin coating, which is effective in preventing adhesive adhesion. However, due to the film thickness of about 30μm, the sharpness of the cutting tool was reduced. As a solution, we polished the coating only on the cutting edge and performed retesting, but this resulted in the cutting edge being uncoated, leading to adhesive adhesion. Continuous cutting of packages became impossible. ■ Adopted Coating 'MRS Coating' 【Free Samples Available】 　▼ We are currently offering free samples of improvement cases for the cutting process and trial sets! ▼

■Chemical Resistance of Teflon / Fluororesin Teflon resin has high chemical resistance and does not dissolve, swell, or react with most acids, alkalis, and organic solvents. ■Reasons for the Excellent Chemical Resistance of Teflon / Fluororesin A major reason for the excellent chemical resistance of Teflon resin and fluororesin is its stable molecular structure. Teflon resin and fluororesin have a molecular structure where carbon atoms and fluorine atoms are connected in a linear chain. The bond energy of the carbon-fluorine (C-F) bond is very strong among chemical bonds, and furthermore, the C-C bond between carbon atoms is completely covered by fluorine atoms in a helical manner. Therefore, even when in contact with chemicals or solvents, they remain inert and do not degrade or dissolve as a resin, which means they have excellent chemical resistance. ■Products Utilizing the Chemical Resistance of Teflon / Fluororesin The chemical resistance of Teflon resin and fluororesin is used in various products in the chemical industry, semiconductor field, and medical and pharmaceutical sectors, such as: - Various gaskets - Packing materials - Pipes and hoses - Storage tanks - Reaction vessels - Heat exchangers *For more details, please download the materials or refer to the link below.*

■What is a release agent? In the industrial field, a release agent is known as a substance applied to improve the separation of molded products from molds. In a broader sense, substances like the flour used to prevent soba noodles from sticking during preparation can also be referred to as release agents. ■Silicone (Silicon) Release Agents Release agents used for molds include silicone and fluorine, depending on the material and conditions. In addition to facilitating mold release, release agents must also have properties that make them resistant to degradation from heat during molding and minimize contamination of the mold. Silicone has high heat resistance and is less likely to degrade with repeated heating during molding. Additionally, due to its low surface tension, it has good wettability on molds, allowing it to reach every corner of the shape, which is one reason it is commonly used as a release agent. ■Release Agents and Coatings In addition to release agents, coatings can also provide release effects. While release agents are an easy means of achieving mold release, they can impose burdens on the working environment, complicate mold cleaning, and lead to variations in the amount applied by workers, potentially negatively affecting the final product. In such cases, release coatings may offer solutions to these challenges. ▼For more details, please see here.

■Reasons why fluoropolymer (PTFE) excels in heat and cold resistance The molecular structure of PTFE consists of carbon-carbon (C-C) bonds surrounded completely by fluorine atoms (F). The breaking of C-C bonds or C-F bonds at high temperatures is one aspect of "PTFE degradation." The C-C bonds are less likely to break because they are protected by the fluorine atoms (F). The bond strength of C-F bonds within PTFE molecules is significantly greater than that of bonds between other atoms. Additionally, the high bond energy of C-F bonds is another reason for its excellent heat and cold resistance. ■Applications utilizing the heat and cold resistance of fluoropolymers In the case of fluoropolymer coatings, for example, baking molds utilize the non-stick properties provided by the coating to prevent baked goods from sticking to the mold. Furthermore, since it also possesses heat resistance, it can be safely used in applications such as baking in an oven. Additionally, in household irons, the heat plate is coated with fluoropolymer to take advantage of its smoothness and heat-resistant properties.

The "MRS Coating" (Mold Release Silicone) is a non-stick, release agent coating that possesses characteristics not found in conventional silicone coatings. In particular, MRS-014 is a thin film with a hardness of 9H, making it hard and excellent in non-stick and release properties. "MRS-014" - Non-stick (release) + Film hardness (9H) It is used to prevent sticking in cutting blades of automatic packaging machines, achieving improved production efficiency and reduced defect rates. [Other Series Features] - Non-stick (release) + Solvent resistance → MRS-102 - Non-stick (release) + Heat resistance (300°C) → MRS-004 - Non-stick (release) + Slipperiness → MRS-003 - Non-stick (release) + Low-temperature processability → MRS-200 Each series has various features, but the standard MRS coating has a smooth surface that makes it easy to wipe off dirt. Additionally, there are grades that show little change in release properties even when cleaned with solvents. *Based on our tests For more details, please download the PDF or contact us.

The purpose of surface treatment for molding dies is as follows: ■ Improvement of Wear Resistance Molding dies experience wear due to friction with materials such as resin and metal during the molding process. If the surface of the die becomes rough due to wear, it can affect the finish of the molded products and shorten the lifespan of the die. ■ Improvement of Corrosion Resistance Molding dies may be subject to corrosion depending on the usage environment. If the die deteriorates due to corrosion, it can affect the finish of the molded products and shorten the lifespan of the die. ■ Improvement of Release Properties Molded products need to be removed from the die after molding. Poor release properties can cause the molded products to stick to the die, making them difficult to remove, or can damage the surface of the die. Surface treatment of molding dies must be selected appropriately according to the type of die and usage conditions. Bicoat, which excels in wear resistance, corrosion resistance, and is expected to improve release properties, is recommended. Bicoat offers many types tailored to specific purposes.
