Achieving the perfect hardness of 55 degrees! We are continuously researching to keep the rubber hardness within ±2 degrees!
Here is an example of the production of a "male downward feeding roller." Due to the urethane rubber hardness of 55 degrees, we aimed for that hardness and carried out urethane rubber casting. Achieving a urethane rubber formulation that targets 55 degrees is quite challenging, but with our experience in liquid casting urethane rubber, we were able to precisely achieve the desired hardness of 55 degrees while considering the isocyanate of the urethane rubber raw materials. [Case Overview] ■ Product Name: Male Downward Feeding Roller 55 Degrees Φ72.7×Φ63×30W ■ Processing: Urethane Rubber Casting (General Type) + Grinding and Polishing ■ Production Period: 5 Days (5 Units) *For more details, please refer to the PDF document or feel free to contact us.

Company information
Ritsusei Chemical Industry Co., Ltd. conducts a consistent process from casting to polishing of urethane products. We handle urethane rubber hardness ranging from low hardness (25-30 degrees) to high hardness (95-100 degrees). Generally, casting urethane is done at atmospheric pressure, and for simple shapes, it can be produced without using molds.
