In selecting waterproof sealants, cushioning materials, and packing materials, there are surprisingly few materials that meet the three elements of "water-stopping ability," "flame resistance," and "weather resistance" at a high level. The reality is that common sponges often have trade-offs, such as "stops water but is flammable" or "flame-resistant but has weak weather resistance." In response to these challenges, the chloroprene rubber (CR) sponge "Gum Sponge C-4305," manufactured by Inoac Corporation, has been chosen as a standard in the industry for many years. In this article, based on the manufacturer's official technical documentation and product characteristics, we will thoroughly explain why C-4305 has gained such trust from many engineers and designers who say, "You can rely on C-4305 for now." We will delve into the secrets of its core performance, including its "closed-cell structure" and "flame-retardant CR formulation," specific applications, and the "processing technology" that allows this material to be shaped flexibly to meet on-site needs. *For detailed content of the column, you can view it through the related links.

In plant and building piping systems, "corrosion" is the greatest risk factor that shortens the lifespan of equipment and can lead to serious accidents. Among these, "galvanic corrosion" (dissimilar metal contact corrosion) that occurs when different metals are connected progresses rapidly and is a phenomenon for which countermeasures are essential. The standard method to prevent this galvanic corrosion is the use of "insulation kits" (insulation bolts and gaskets). Among these, the "insulation lining bolt," which has the bolt shaft coated with fluororesin, is particularly excellent in terms of workability and reliability, and can resolve installation issues on-site (such as interference with gaskets). This article will thoroughly explain the mechanism of why "galvanic corrosion" occurs, why insulation lining bolts are supported on-site, their structural advantages and specifications, and the appropriate selection methods tailored to on-site standards. *For detailed content of the column, please refer to the related links.

The challenges of "cutting processing" in manufacturing sites always lie in balancing "cost," "delivery time," and "accuracy." While dedicated mold presses offer high precision, they come with high initial costs and long lead times. On the other hand, hand cutting and cutting plotters have no initial costs, but they tend to have longer takt times during mass production, resulting in higher unit prices. A suitable solution to this dilemma is the long-established technique known as "Thompson processing (die cutting)." This article will thoroughly explain the basics of Thompson processing, why Daiko is committed to "in-house mold production," its technical advantages, and its ability to handle a wide variety of materials such as joint sheets, rubber, sponge, and PTFE. *For detailed content of the column, you can view it through the related links.

In manufacturing environments where "hygiene management" is the top priority, such as in food, beverages, pharmaceuticals, and cosmetics, the selection of rubber components (gaskets, seals) used is extremely important. This is because it is not only about preventing leaks but also about ensuring safety for the human body (compliance with regulations) and significantly reducing the risk of foreign material contamination. A suitable solution to meet such stringent requirements is the "EP-5165-W" developed by Iruma River Rubber Co., Ltd. This is a special grade of white (white) EPDM (ethylene propylene rubber) that is compliant with food hygiene laws and excels in weather resistance and chemical resistance.

In the manufacturing environment of products that enter the human mouth, such as food, beverages, pharmaceuticals, and cosmetics, the safety of "rubber packings" and "gaskets" used in equipment is as important, if not more so, than the safety of the products themselves. If harmful substances were to leach from the rubber and contaminate the products, the trust in the company would collapse instantly. Not an ambiguous "food grade," but truly safe silicone rubber based on "solid evidence" from a public testing organization. That is the "Silicone Rubber Sheet SN-50" from Osaka Rubber Co., Ltd. In this article, we will thoroughly explain why SN-50 has gained absolute trust in the food and medical fields, based on the test report (No. 452-21-A-0055) issued by the Chemical Substance Evaluation and Research Institute (CERI), detailing its legal basis and test results. *For detailed content of the column, please refer to the related links.

In the manufacturing fields of food, pharmaceuticals, and cosmetics, achieving a balance between "safety (compliance with the Food Sanitation Act)" and "durability (heat and chemical resistance)" is an eternal challenge. While silicone rubber and EPDM are safe and easy to use, they may not withstand high-temperature oils, certain chemicals, or high-pressure steam. This is where "Food Sanitation Act-compliant fluorine rubber IF-900," proudly offered by Iruma River Rubber Co., Ltd., comes into play. IF-900 is a high-grade product that maintains the inherent heat and oil resistance of fluorine rubber while complying with the Food Sanitation Act (Ministry of Health and Welfare Notification No. 370).

The "sheet gasket," which is the most familiar sealing material on site, is widely used due to its convenience of being processed with scissors or cutters, such as joint sheets and fluororesin sheets. However, when it comes to its "thickness," are you not deciding it based on a vague feeling? In fact, the belief that "thicker is stronger and safer" for sheet gaskets is a significant misconception. On the contrary, it is not uncommon for overly thick selections of sheet gaskets to cause critical leakage problems precisely because they are sheet gaskets. In this article, we will thoroughly explain why "thin" is recommended for sheet gaskets, as well as the situations where "thick" is necessary, and the criteria for selection. *For detailed content of the column, please refer to the related links. For more information, feel free to download the PDF or contact us.*

"A leak occurred from a flange that was supposed to be tightened to the specified torque a few months later." "After performing a re-tightening (hot bolting), the gasket was damaged." Such troubles are not uncommon in the maintenance of plants and piping systems. The main cause cited is the physical phenomenon specific to gaskets known as "stress relaxation." This article will explain the mechanism of stress relaxation, the differences in behavior depending on the material, and appropriate management methods to maintain long-term sealing performance. *For detailed content of the column, you can view it through the related link. For more information, please download the PDF or feel free to contact us.*

Have you ever been troubled by such inexplicable minor leaks at the piping site? It may not be "interface leakage" that leaks from the gap between the gasket and the flange, but rather "permeation leakage," which leaks through the material of the gasket itself. In particular, when using "sheet gaskets" such as joint sheets, the risk of this permeation leakage is always present. The most effective countermeasure for this is to "make the gasket thinner." In this article, we will explain the often-overlooked mechanism of "permeation leakage" and the physical reasons why thick gaskets can lead to leaks. *For more detailed information, you can view the related links. For further details, please download the PDF or feel free to contact us.*

"Even after tightening, it keeps dripping from the gap between the flange and the gasket." "When I reused old piping, even though I put in a new packing, it won't stop." "There is rust and scratches on the flange surface, but there is no budget for replacement." The most frequently encountered trouble in piping maintenance is "Interface Leakage." Unlike "permeation leakage," which passes through the material of the gasket itself, this phenomenon occurs when fluid escapes through the "gap" between the gasket and the flange surface. The key to stopping interface leakage is "familiarity." In this article, we will explain why interface leakage occurs and how to approach rough flanges to stop the leakage. *For more detailed content of the column, please refer to the related link. For more information, feel free to download the PDF or contact us.

In the field of plant maintenance, issues with steam line leaks are never-ending. Many of these problems stem from a "selection mistake" where "joint sheets for general piping (water and oil)" were carelessly used in steam piping. "I thought it would be fine because the catalog said it was heat-resistant up to 150°C." This complacency can be fatal. There are clear physical reasons why only "steam-specific" materials should be used for steam piping. This article will explain the mechanism of "thermal degradation (hardening)" that occurs when the wrong gasket is used, as well as the risks of "re-tightening," which should absolutely be avoided, based on technical materials from Nichias. *For detailed content of the column, please refer to the related links.
