DESCRIPTION: N3505 is a blend of reinforcing materials with nitrile
latex, produced by the wet process. N3505 offers excellent torque
retention, resistance to crush extrusion and sealability. N3505
is recommended for use in solid core and perforated core head gasket
applications. Because of its strong thermal properties and sealability,
N3505 is also recommended for use in high temperature soft gasket
and exhaust applications.
