Ultem Machined Parts
Ultem is a popular high strength plastic resin, ideal for parts that require strength and excellent thermal and dielectric properties. It has an extremely high resistance to heat and moisture and can withstand multiple cycles in hot water or steam. Ultem also has one of the highest dielectric strengths of any thermoplastic, making it suitable for applications in the aerospace and electronics industries.
Ultem has a machining cost factor of 0.7 when compared to steel 12L14/
