We would like to introduce our "Rodent Repellent Rubber." It contains capsaicin, a component that rodents dislike, which helps suppress their chewing behavior. Additionally, there will be no need to store covers or rubber products, or to use rodent repellent agents. It is also possible to consider repellent rubber for other animals, birds, and insects (taste and hearing). 【Application Examples】 ■ Packing for hot water and water supply machines ■ Water hoses ■ Gas hoses *For more details, please refer to the PDF materials or feel free to contact us.

• Rubber

We would like to introduce the "heat-expandable rubber" that we handle. When exposed to high temperatures, the special additives inside the rubber become activated and expand. This helps control the spread of smoke and flames during a fire, ensuring people have enough time to evacuate and enhancing safety. Additionally, we can consider various rubber materials and expansion ratios. Please feel free to contact us when needed. 【Features】 ■ Special additives activate and expand ■ Blocks gaps and vents to suppress the spread of fire ■ Enhances safety by ensuring evacuation time *For more details, please refer to the PDF document or feel free to contact us.

• Rubber

We would like to introduce our "mold-inhibiting rubber" that we handle. It contains anti-mold ingredients that prevent the growth and reproduction of mold and fungi, thereby suppressing mold occurrence. In addition to mold prevention, it is also expected to have effects against moss, antibacterial properties, and virus inactivation. If you have any inquiries or requests, please feel free to contact us. 【Features】 ■ Suppresses mold occurrence due to the inclusion of anti-mold ingredients ■ Expected effects against moss, antibacterial properties, and virus inactivation ■ Possibility of obtaining the SIAA mark *For more details, please refer to the PDF document or feel free to contact us.

• Rubber

Introducing a soft yet strong rubber (low hardness) that feels like human skin. The typical hardness of rubber is above 30°, but this rubber has a soft hardness around 10°, similar to human skin. Generally, as hardness decreases, tensile strength tends to decrease as well; however, this low-hardness rubber possesses high tensile strength. Applications include vibration-damping rubber for precision instruments, shock absorption, and rubber mats for gyms. If you have any inquiries or requests, please feel free to contact us. 【Examples of Applications (Partial)】 ■ Vibration-damping rubber for precision instruments (such as optical disc drives) ■ Alternative to rubber sports (improved sealing) ■ Shock absorption (seismic mats, head protectors, etc.) ■ Creak prevention (automobiles, beds, etc.) ■ Rubber mats for gyms *For more details, please refer to the PDF document or feel free to contact us.

Rubber mixing is done using a mixing machine. Mixing machines include open rolls, pressure kneaders, internal mixers, and Banbury mixers, and it is important to select the appropriate product according to the type and amount of rubber material being mixed. Additionally, there are large-capacity mixing machines for rubber manufacturing in factories, as well as small open rolls and pressure kneaders at the lab level for research and prototyping, which are essential equipment for rubber manufacturing and research. 【Types of Mixing Machines】 ■ Open Roll ■ Pressure Kneader ■ Internal Mixer ■ Banbury Mixer *For more details, please refer to the PDF document or feel free to contact us.

The design of rubber products goes through the processes of "shape consideration - material consideration - structural analysis," after which prototypes are molded, created, and evaluated. If the evaluation of the prototypes indicates that countermeasures are necessary, the processes of shape consideration, material consideration, and structural analysis are repeated, aiming for mass production. Detailed information can be found through the related links.

There are various types of rubber measurements depending on the purpose. Please note that the shape of the test specimen sample varies depending on the measurement method and measuring equipment. Generally, a sheet with a thickness of 2mm is punched (or cut out) into a dumbbell shape suitable for testing to create the desired test specimen sample. You can check the detailed information from the related links. 【Main Measurement Methods for Rubber (Partial)】 ■ Hardness Measurement ■ Specific Gravity Measurement ■ Tensile Test ■ Compression Set Test ■ Curing Test ■ Tear Test *For detailed content of the column, you can view it from the related links.

To shape rubber into a product form, a mold is necessary. Molds are created to match the shape of the rubber parts, and molding is carried out. In this column, we introduce the types of rubber molds, molding methods, finishing techniques for the molded products, and know-how on defects commonly seen in rubber products and their countermeasures. Please take a look at the related links. 【Contents】 ■ Molding methods and mold structures for rubber ■ Finishing of rubber products ■ Defects observed in rubber products *For detailed information on the column, please refer to the related links.

"Nitrile rubber (NBR)" is a type of diene rubber that has excellent oil resistance due to its double bonds in the main chain. Because of its superior oil resistance, it is used in applications such as hoses, gaskets, and seals around oil. On the other hand, due to the presence of double bonds in its structure, it has poor heat resistance and weather resistance, and it is inferior in cold resistance. 【Material Properties】 <Advantages> ■ High oil resistance derived from the polarity of the nitrile group <Disadvantages> ■ Poor heat resistance and weather resistance due to the presence of double bonds in its structure ■ Inferior cold resistance *For more details, please refer to the related links or feel free to contact us.

Rubber can enhance its performance by mixing and kneading the polymer, which is the raw material, with compounding materials. This process of mixing and kneading rubber materials is called "rubber kneading." Kneading is the process of obtaining a compound by uniformly mixing and dispersing the polymer and compounding materials according to the formulation design, using kneading machines such as rollers and mixers. Kneading is a crucial step in the manufacturing line of rubber products that affects their quality, and any mistakes in the kneading process can have a significant impact on subsequent processes. Therefore, kneading is an important step that must incorporate various materials according to the rubber formulation. 【Rubber Kneading Process】 ■1. Pre-kneading process: Kneading only the polymer in the kneading machine ■2. Kneading process: Kneading various compounding materials into the pre-kneaded polymer ■3. Discharge process: Discharging the kneaded rubber material at the desired size *For more details, please refer to the related link page or feel free to contact us.
