986A is a compressed EPDM Aramid reinforced Fiber sheet. The combination of aramid fibers and EPDM creates a sheet material that withstands the effect of aggressive acid and alkalies including white, green and black liquor – with a minimum of weight loss. In addition, the EPDM handles steam up to 400F. These characteristics make 986A well suited in the pulp & paper industry.
In addition, 986A can be used in such demanding chemicals as caustics, dilute acids, brake fluids, silicone fluids, ketones, and phosphate esters. This sheet gasket also provides high resistance to weathering, oxygen, and ozone, and is compatible with animal and vegetable oils.
986A is off white in color and and is made with EPDM/Aramid Fiber.
986A is made with an EPDM binder giving it the ability to be used in the more severe compressed sheet applications.

Note: ASTM properties based on 1/16″ sheet thickness except ASTM F38, which is based on 1/32″ sheet thickness. This is a general guide only and should not be the sole means of accepting or rejecting this material. The data listed here falls within the normal range of product properties but should not be used to establish specification limits nor used alone as the basis of design.
Can be used in steam, alkalis, brake fluids, phosphate esters, dilute acids, animal and vegetable oils.
