Rubber Raw Materials
Based on extensive experience in compounding design with various natural and synthetic rubber materials including NR, NBR, H-NBR, CR (Neoprene), EPDM, CSM (Hypalon), IIR, and Fluoro rubber (Viton), we develop and supply optimal rubber compounds tailored to process-specific requirements such as wear resistance, oil resistance, chemical resistance, heat resistance, cold resistance, and ozone resistance. We possess the technology to formulate various rubber materials with chemical properties (acid resistance, wear resistance, chemical resistance, heat resistance, cold resistance, oil resistance, etc.) and physical properties (elasticity, tensile strength, compressive strength, etc.) suited to each customer's operating environment.
