Technical Information and Specifications

Restoreplus Reference Fluid ISO IRM-901 is prepared based on the reference and the common technical values of equivalents replacing products in this segment are as follows:

• High Paraffinic Content: IRM-901 is a highly refined paraffinic oil. This structure creates a Low Swelling effect on rubber materials, allowing testing of material oil resistance under the toughest conditions.

• ASTM D5964 Compliance: This standard defines the chemical limits of oils used to measure changes in the physical properties of elastomers. IRM-901 is essential for Official Test Protocols.

• Narrow Specification Range: Unlike standard motor or industrial oils, the aniline point and viscosity values of these fluids are kept within a very narrow tolerance range. This ensures Repeatable Test Results in laboratories worldwide.

• Elastomer Interaction: Used to measure volume change, hardness loss, and tensile strength changes especially in sealing elements such as Nitrile (NBR), Fluorocarbon (FKM), and EPDM.

• Thermal Stability: Due to prolonged exposure at high temperatures like 70°C, 100°C, or 150°C during test processes, oxidation resistance is very high.

• Aniline Point Control: The aniline point, which identifies the aromatic content of the oil, directly affects the swelling of materials. The high aniline point of IRM-901 proves it to be a Non-Aggressive test oil.

Application Area: This product is safely used in the production of automotive sealing elements, hose and belt test laboratories, aerospace materials research and development centers, and rubber compound quality control units.
