IRM 901 Oil is a high-quality reference oil specifically formulated for evaluating the compatibility of rubber and elastomeric materials with petroleum-based oils. Formerly known as ASTM Oil No. 1, this oil is recommended in the ASTM D471 standard for immersion tests to determine the effect of liquids on rubber properties. IRM 901 Oil is essential for laboratories and industries aiming to ensure the durability and performance of rubber components in various applications.
