By selecting the material for the polyurethane rollers used with hand pallets in our factory, we can achieve a longer lifespan. Standard polyurethane can break down or deteriorate within 2 to 3 years due to hydrolysis and load-bearing issues. However, we can select materials that excel in hydrolysis resistance and load-bearing capacity. Features: - At Somal Rubber, we can analyze existing materials to some extent determine the characteristics of the polyurethane you are currently using. - Various selections are possible, whether prioritizing cost performance, increasing strength, or enhancing load-bearing performance. - We can produce small-scale prototypes from just one piece, regardless of shape. *For more details, please refer to the related links or feel free to contact us.

By changing the caster wheels made of urethane used in the factory to an anti-static type, it is possible to prevent dust accumulation. Regular urethane generates static electricity due to friction, causing dust and dirt to collect. However, by using anti-static urethane, static electricity is dissipated, preventing the adhesion of dust and dirt. This is mainly used in clean rooms and factory floors. Features: - Somar Rubber can convert existing urethane to an anti-static type, allowing for static electricity prevention without changing usability. - Prototyping in small quantities, starting from one piece, is possible in any shape. *For more details, please refer to the related links or feel free to contact us.

By replacing the cushioning material of pallets that transport automotive parts from rubber and resin (such as plastic and nylon) to urethane, wear resistance is improved, allowing for a longer lifespan. Rubber has excellent grip and cushioning properties, while resin excels in load-bearing capacity and strength. Urethane offers grip and is superior in wear resistance and load-bearing capacity, making it a material that combines the best of both. 【Features】 ■ Somal rubber urethane has high wear resistance, and a longer lifespan is expected compared to rubber and resin. ■ Prototyping in small quantities, starting from one piece, is possible for any shape. *For more details, please refer to the related links or feel free to contact us.

On our website, we introduce our achievements in solving the challenges faced by theme parks. The wheels of high-speed roller coasters, which operate at speeds of 140 km/h and experience gravitational forces of 4G to 6G, inevitably suffer from internal damage due to heat buildup when made from standard polyurethane, leading to delamination or a decrease in surface hardness, resulting in a sticky state. Therefore, by adopting "VULKOLLAN," we developed wheels with extremely high load-bearing capacity, wear resistance, and heat resistance that can withstand high-speed rotation and heavy loads. Please take a look at our website. [Overview of Achievements] ■Challenges - There are no materials that can withstand high-speed roller coasters. ■Solutions - Developed wheels that can withstand high-speed rotation and heavy loads by adopting VULKOLLAN. - Implemented curing to the core material through injection molding, resulting in safer wheels. *For more details, please refer to the PDF materials or feel free to contact us.

On this homepage, we introduce our achievements in solving the challenges of multi-story parking garages. The rotating table has poor dynamic load balance, which places a significant burden on the tire section. As a result, nylon wheels are commonly used; however, due to their very hard material, they produce a "clattering" noise that resonates in the surrounding area, leading to noise issues. By adopting high-rebound elastic polyurethane, we have managed to reduce the noise even for rotating tables with heavy loads. Please take a look at our company website. 【Overview of Achievements】 ■Challenges - The noise from the rotating table is loud. ■Solutions - The noise has been reduced even for rotating tables with heavy loads. - The rotating table can now be operated at night. *For more details, please refer to the PDF materials or feel free to contact us.

On this homepage, we introduce our achievements in solving the challenges faced by copier manufacturers. When using general synthetic rubber for the paper feed rollers of copiers, the evaporation of oil causes changes in the coefficient of friction (μ), making it impossible to achieve consistent paper feeding. Therefore, by using foam urethane produced through our unique method called "independent bubble foaming," we have ensured that there is no change in μ even after long-term use, maintaining feeding accuracy. Please take a look at our company website. 【Overview of Achievements】 ■Challenges - Changes in the coefficient of friction (μ) ■Solutions - By using foam urethane, feeding accuracy is maintained even after long-term use - Developed rollers made of Somar urethane that do not decrease in wear resistance along with feeding accuracy *For more details, please refer to the PDF materials or feel free to contact us.

On this homepage, we introduce our achievements in solving the challenges faced by hospitals. When hospitals introduced MRI machines, they encountered issues with the casters rolling poorly during transport to the installation site, leaving black marks on the floor. This was a concern even during maintenance, which occurred every few years. To address this, we adopted a polyurethane material that is wear-resistant and has high resilience for the casters. This allows for smooth movement even with a few relocations each year, and the polyurethane prevents marks from being left on the floor. 【Overview of Achievements】 ■Challenges - The casters of the MRI leave black marks on the floor. ■Solutions - We used wear-resistant and high-resilience polyurethane for the casters, eliminating flat spots. - Smooth movement is achieved even with a few relocations each year, and no marks are left on the floor. - Due to the specialized nature of the MRI casters, we conducted small-lot production. *For more details, please refer to the PDF document or feel free to contact us.
