MIL-R-25988 Silicone

MIL-R-25988 silicone rubber from ElastaPro meets the requirements of a U.S. military specification for fluorosilicone elastomer rubber designed for oil and fuel resistance, particularly in aerospace applications. It covers materials used for O-rings, molded parts, sheets, strips, and extruded shapes. MIL-R-25988 was superseded by MIL-DTL-25988, which was superseded by AMSR25988.

Key Characteristics

  • Oil and fuel resistant: The addition of fluorine in the compound provides excellent resistance to petroleum-based fuels and oils.
  • Wide temperature range: It can operate in extreme temperatures.
  • Diverse forms: The material is available in a variety of forms, including O-rings, sheets, strips, molded parts, and extruded shapes.
  • Classifications: The specification classifies the materials into types, classes, and grades based on properties like hardness, tensile strength, and elongation.
    • Type 1: Primarily for O-rings.
    • Type 2: Used for sheets, strips, and extruded shapes.
    • Class 1: General-purpose use.
    • Class 2: High-strength compounds.

Applications

  • Seals and gaskets for military aircraft.
  • Hydraulic equipment O-rings.
  • Production machinery door seals.
  • O-rings, molded parts, and other components used in aerospace and aeronautical applications.
