Plastim Ultem

Ultem

Overview

Ultem is a high performance engineering plastic offering high mechanical and electrical properties as well as excellent flame and heat resistance. It is UL94 VO rated (self-extinguishing) and USP Class VI compliant. Capable of withstanding repeated autoclaving cycles. Maximum continuous operating temperature is 170°C.

Benefits:

Resistance to high temperature.
Flame resistance: self-extinguishing, low oxygen index.
High tensile stress, flexural strength, E.modulus.
Good chemical resistance.
Excellent electrical properties.
Physiologically inert, therefore FDA compliant.


Weaknesses:

The cost is higher than conventional engineering plastics.
Lower shock resistance.
Unsuitable coolants used during machining can lead to subsequent stress cracking.

Applications:

Structural probes.
Insulators.
Radomes.
Manifolds in pharmaceutical process equipment.
Clamps to connect circuit boards.
Sight glasses and in aircraft instrumentation.
