High Dielectric & Thermal Performance
ULTEM 1000 combines outstanding flame retardancy (UL94 V-0) with exceptional electrical insulation and high dimensional repeatability across fluctuating thermal environments.
Machining & Stress Relief Protocol
Tooling: Uncoated micrograin carbide with high positive shear rake angles.
Thermal Annealing: Post-machining annealing at 200°C (392°F) is recommended for complex manifolds to relieve residual stress and prevent crazing.
Cooling: Water-soluble coolant or cold vortex air blast. Avoid chlorinated degreasers.
Frequently Asked Questions
Can ULTEM 1000 withstand repeated steam autoclave sterilization?
Yes, ULTEM retains its structural integrity and mechanical properties through thousands of high-temperature steam sterilization cycles.
How to prevent stress crazing in machined ULTEM manifolds?
Use sharp cutters with light finishing cuts and perform an oven thermal stress-relief cycle at 200°C before assembly.
