<For customers in the Tokai area> We will evaluate whether the heat resistance is sufficient and if the material properties are stable! We will propose suitable materials.
Matsumoto Sangyo Co., Ltd. conducts "aging resistance tests." Rubber sheets in the shape of dumbbells are exposed at specified temperatures and times, and the tensile strength, elongation rate, and hardness before and after exposure are measured to evaluate heat resistance. The physical properties of rubber materials cannot be determined by appearance alone. However, even similar materials can have significantly different properties depending on the manufacturer. Our company evaluates whether the heat resistance is sufficient and whether the physical properties are stable, and we propose appropriate materials. A must-see for customers in the Tokai area, especially in Shizuoka, Aichi, and Yamanashi Prefectures! Feel free to contact us, even if it's just for an initial consultation. [Test Conditions] ■ Rubber Material: EPDM (NOK 70°, Company A 60°, Company B 70°, Company C 70°) ■ Sample Size: JIS K6251 No. 3 Dumbbell ■ Exposure Temperature: 120℃ ■ Exposure Time: 70 hours *For more details, please refer to the PDF document or feel free to contact us.

Company information
Matsumoto Sangyo Co., Ltd. was established as an agent for NOK Corporation, a top manufacturer of sealing products, and has since added LOCTITE products (now Henkel Japan), a global brand of liquid gaskets and adhesives, to its lineup, continuing to this day. Sealing products are used in various machinery and equipment, often in a discreet manner, to prevent oil and water leaks and to block the intrusion of external debris and foreign objects. These products are essential mechanical components found in everything around us, from automobiles and motorcycles to construction machinery, aircraft, ships, railway vehicles, agricultural machinery, oil plants, home appliances, household rubber goods, and plumbing systems. Sealing products exist in an almost infinite combination of shapes, dimensions, and materials tailored to specific applications, sealing fluids, environmental conditions, and temperatures, resulting in a wide variety of products. At Matsumoto Sangyo Co., Ltd., we leverage the expertise accumulated since our founding to comprehensively assess "quality," "price," "production capacity," and "supply system," regardless of domestic or international manufacturers, to propose products that meet our customers' needs.
