PES

PES is a transparent, high-performance polymer known for its dimensional stability at high temperatures. This high-temperature engineering thermoplastic has good transparency and flame resistance, and it is one of the lowest smoke-emitting materials available. The low flammability and smoke generation makes it a good candidate to meet FAA regulations for aircraft interior parts.

PES polymer offers high mechanical strength and rigidity, coupled with relatively low notch sensitivity. Polyethersulfone is an ideal choice for use in applications with tight tolerances and little dimensional change within a wide temperature range.
