Product Spotlight: Redco ULTEM

High performance plastics face extra challenges other materials do not. Because of the prevalence of consumer grade plastic, unfortunately plastic with much of the public has become synonymous with “cheap” – low price and low quality. Unfortunately, this is a complete myth for the three grades of plastics (engineering/industrial, high performance, and imidized) that are above consumer grade plastics. In fact, at the higher tiers of quality plastics widely outperform metal and other traditional materials in most applications. And this does come with a subsequent increase in product cost (though usually a lower “lifecycle cost”). But for your money you get quality in a phenomenal material.

ULTEM (polyetherimide – “PEI”) in its virgin form has an interesting amber/translucent color. It handles hot water and air well, up to 332 Fahrenheit in continuous operation. Its resistance to repeated steam sterilization makes it a prized material for medical tools and devices. ULTEM is also very useful to the electronics industry due to its dielectric constant and arc resistance. It is also resistant to gamma radiation and does not absorb water. ULTEM is considered a dimensionally stable plastic with high strength and rigidity allowing it to be machined precisely to tighter tolerances than other plastics would allow. It is also available in 10, 20, and 30% glass filled grades to offer even higher dimensional stability.

If you have a high heat application requiring a precisely machined part ULTEM may be the optimal plastic for you. To discuss this or other plastics please contact us.
