Padespahan Laboratory

Sepahan Rubber Industries Company Laboratory

The Sepahan Rubber Industries Company Laboratory was established in 2017 with the aim of improving the quality of products, establishing a research and development unit in cooperation with universities, defining joint research projects, and improving the skills and efficiency of employees. This laboratory, having received the necessary consultations to achieve ISO/IEC 17025 certification, has now fully implemented all the managerial and technical clauses of the 17025 standard.

Laboratory activities include:

• Quality control at various stages of production and final approval of all company products, including compounds, parts, roller coatings, etc.
• Quality control and review of the properties of materials entering the company
• Determining appropriate production conditions, including pressure, temperature, time, mold design, etc.
• Providing forms for recording control parameters according to parameters important to the customer and product quality control labels
• Designing the necessary formulations according to customer needs
• Providing product property certificates
• Consulting in the field of designing the required properties according to customer technical information
• Performing tests to measure the physical and mechanical properties of rubber according to the latest standards
• Providing test reports based on the field of activities defined in the 17025 standard
