Abstract:
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 100oC. 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.
