Disogrin Polyurethane (AU) Compounds

Disogrin 7695 and 9259 Urethane (AU) Material Description:

Disogrin 7695 and 9250 are Simrit’s proprietary compounds used for fluid power seals and are unlike any polyurethane in the industry today. Disogrin 7695 has been especially developed to be water, acid and base resistant. While many polyurethane seals are vulnerable to hydrolysis, or degradation by water, seals made of Disogrin 7695 are compatible with both mineral oils and water, fitting a more diverse range of applications. Disogrin 7695 is therefore specially suited for biodegradable fluid applications common in forestry, landscaping, agriculture, marine, oilfield, and water treatment.

Benefits of Disogrin 7695 Urethane (AU)

  • Compatible with water and resistant to hot water up to 250 degrees F, making it a possible alternative to chloroprene and EP rubbers
  • Compatible with hot vegetable and mineral oil based fluids
  • Resistant to acidic and basic solutions (pH 2-13) up to 220 degrees Fahrenheit
  • Off-the-shelf availability in empirical and metric sizes

Disogrin 9250 is more robust, wear-resistant, withstands higher pressure and lasts longer than any other formula on the market. Disogrin 9250 is used in Simrit rod seals, piston seals, cover seals, wipers and O-rings.

Benefits of Disogrin 9250 Urethane (AU)

  • Improved compression set
  • Resistance to high pressure extrusion
  • Greater heat resistance
  • Increased wear resistance
  • Improved fluid compatibility
  • Abrasion resistance
  • Longer life
  • Off-the-shelf availability in standard and metric sizes

Temperature ranges will apply to the majority of media for which the material is potentially recommended. With some media however, the service temperature range may be significantly different. ALWAYS TEST UNDER ACUTAL SERVICE CONDITIONS.

ESP’s shelf life recommendation is based on the ARP 5316 standard and intended to be utilized by those organizations who do not already have specific recommendations for the control of elastomeric seals. It should be noted that the packaging of the elastomeric seals prior to assembly into a product is an integral part of the controlled storage procedure. It provides a positive means of product identity from the time of manufacture, to the time of assembly.
