Technical Information and Features

Restoreplus Referance Fluid ISO IRM-902 is prepared with reference to and is a substitute for products in this segment with shared technical values as follows:

• Medium Aromatic Content: IRM-902 has a higher aromatic content than IRM-901 but lower than IRM-903. This structure creates a Medium Swelling effect on elastomers, simulating real use scenarios.

• ASTM D5964 and ISO 1817 Compliance: This product is fully compatible with International Test Standards that measure volume, mass, and hardness changes of vulcanized rubbers against oils.

• Precise Aniline Point: The aniline point, determining how much the oil will penetrate into the material, is fixed at a 93°C level with very narrow tolerance for test accuracy.

• Elastomer Performance Tests: It is a basic criteria for the Oil Resistance classification of sealing elements like NBR (Nitrile), HNBR, and ACM used especially in the automotive and machinery industry.

• Repeatability: The chemical analysis for each batch product from serial production is identical. This ensures that tests conducted at different times provide Comparable Results.

• Oxidation Stability: It possesses High Thermal Stability to prevent the deterioration of the oil's properties in long-term immersion tests (e.g. 70 or 166 hours at 100°C).

• Viscosity Control: The viscosity value, affecting the rate of penetration of the material's surface during the test, is carefully maintained within the ISO VG 20-32 range as required by standards.

Application: This product is safely used in the approval processes of automotive sealing parts, elastomer tests in the defense industry, and in the quality laboratories of hose and gasket manufacturing facilities.
