Disogrin® 7695 and 9250 for Fluid Power Seals -Image

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.

The benefits of Disogrin® 7695 are:

· Compatible with water and resistant to hot water up to 250 degrees Fahrenheit, 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.

The benefits of Disogrin® 9250 are:

· 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 empirical and metric sizes
