Notice of Participation in the 5th Sustainable Materials Exhibition (SUSMA) from November 12 (Wednesday) to November 14 (Friday), 2025.

A thermoplastic styrene elastomer that has rubber-like elasticity and can be molded with general-purpose injection molding machines! Contributes as a material for various product development with high transparency!

"Thermoplastic Styrene Elastomer (TPS)" is a highly versatile thermoplastic resin that offers great freedom in design and manufacturing. Compared to the time-consuming processing of rubber, it can be processed using methods employed for thermoplastic plastics, such as extrusion molding and injection molding. Our company is particularly focused on the development of low-hardness and highly elastic styrene elastomers among thermoplastic elastomers. Samples are available for distribution, but due to limited availability, there may be a delivery time of about one month after receiving your request. 【Features】 ■ Low hardness A0–A30 ■ High transparency ■ High elasticity (kickback property) ■ Proposals for custom orders that major manufacturers are hesitant to handle ■ Can be molded using general-purpose injection molding machines *For more details, please download the PDF or feel free to contact us.

We would like to connect with companies considering climate change mitigation businesses using SDGs, business, and biomass materials towards a decarbonized society.

Our company is capable of creating a wide range of cured material properties by combining resins, hardeners, and various additives. Since our products are liquid materials, we can blend liquid and powdered biomass materials to create new value. We also assist in obtaining biomass certification from third-party organizations.

High-strength adhesive that can be set without heating | Can be adjusted after bonding, sets in 4 hours, allowing for versatile usage! Kobayashi's room temperature curing technology!

We often hear concerns such as 'the smell is bothersome when using adhesive' and 'heating cannot be applied when curing the adhesive' in bonding and joining scenarios. Kobayashi's high-strength adhesive, utilizing room temperature curing technology, can be applied to the items to be bonded, allowing for a correction time, and achieves over 90% of its final strength within 24 hours. 【Features】 ◆ Capable of bonding the same materials as well as different materials such as metal and FRP ◆ Demonstrates stable bonding strength of over 20 MPa with typical metals (SPCC, SUS, etc.) and FRP ◆ Contains no volatile components such as organic solvents, resulting in low odor and excellent shelf life ◆ No heating required, making it suitable for bonding large items and on-site applications ◆ Resistant to water, oil, organic solvents, and high temperatures At Kobayashi, we are engaged in product development that leverages the flexibility of liquid resin products. We can also consult on controlling properties and working time before curing, as well as improving characteristic values and imparting functionality after curing. *For more details, please download the PDF or contact us directly.

We will contribute to the SDGs with adhesive!

Are you struggling with your recent efforts towards the SDGs? Do you want to contribute to the SDGs in any way? Our adhesives can help with that! For example, If you want to reduce utility costs... we can suggest adhesives that cure at room temperature as well as heat-cured ones! If you feel unwell due to solvent odors... we can propose solvent-free adhesives! To contribute as much as possible, we also offer "adhesives" made from biomass-derived materials and biomass materials tailored to your needs. Please take a look at our materials!

**Seminar Points** Improvement means changing standards for the better. There can be no improvement where there are no standards. If there are no standards, start by creating them. Standards are "rules." What to decide are "procedures," "methods," and "timing." This seminar is focused on determining "procedures" and creating "work instruction documents." **"Without standards, there is no improvement" — Learning from Toyota's teachings on documentation in the workplace** The source of Toyota's strength lies in the concepts of "improvement" and "standardization." At the core of this is a culture of making insights and skills visible in the workplace and documenting them. In other words, it is a system of knowledge transfer through documentation. Relying on the experience and intuition of veterans can be a strength in the workplace, but it also carries the risk that quality may change when people change. By ensuring that everyone performs tasks in the same way, we can achieve the same quality products (good products) in the same amount of time. First and foremost, the development of "work instruction documents" is essential. When presenting work instruction documents in video format, it is also a prerequisite that this "foundational document" is well established. *For more details, please download the PDF or contact us.*
