A method of making a glass mat includes providing an assembly of glass fibers, applying a binder composition to the assembly of glass fibers, wherein the binder includes an organic resin, and curing the binder composition while dimensionally constraining the assembly of glass fibers. Dimensional constraining includes directly contacting a first major surface and a second major surface of the assembly of glass fibers between two substantially parallel surfaces. Further provided is a glass mat that includes an assembly of glass fibers, wherein the assembly of glass fibers are substantially randomly oriented with a tensile anisotropy of less than about 6 in any two directions. The glass mat has a decreased surface roughness and a decreased caliper compared to an equivalent glass mat having an assembly of naturally packed glass fibers with an equivalent fiber diameter size.

A seal ring includes a weld and a thermoplastic material. The thermoplastic material has a weld elongation-at-break of at least 3%. The thermoplastic material can have a glass transition temperature of at least 100&#xb0; C. The thermoplastic material with the weld can have a weld elongation-at-break of at least 3%. The seal ring can have a circumference of at least 0.62 meters. The seal ring can have a coefficient of friction of not greater than 0.45.

A method of forming a seal ring includes heating an extruded rod to a temperature above a glass transition temperature. The extruded rod has first and second ends. The method further includes bending the extruded rod into a circular structure while the temperature is above the glass transition temperature, joining the first and second ends of the extruded rod to form a semi-finished ring, and annealing the semi-finished ring.
