Nylon For Specialty Applications

Nylon is a family of plastics with several different additives that make them suitable for applications where natural-grade nylon isn’t optimal or won’t be successful. There are three grades of nylon specifically that should be highlighted for their properties in applications with unique demands.

Firstly Redco SL which offers a low coefficient of friction with excellent wear resistance. It was developed for applications where external lubrication is either very difficult or impossible. Redco SL performs better than other nylons and many plastic where the part is rarely accessed for maintenance.

Secondly, Redco glass-filled nylon serves very well for prototypes. The glass filling results in a very dimensionally stable part which can be held to tighter tolerances. This part also has the lowest “cold flow” of any nylon. If you’re looking for a “proof of concept” part than Redco glass filled nylon is an excellent choice.

Lastly, Redco blue is a grade of nylon for high-heat applications, able to withstand up to 250 degrees Fahrenheit ongoing in application. This alone isn’t especially unique, as several plastics such as PTFE handle temperatures just as high. However, Redco blue nylon is the best “bang for your buck” for a heat-tolerant plastic. The alternatives such as the aforementioned PTFE, PEEK, ULTEM, etc. are all much more expensive. If you’re having trouble finding a heat-tolerant plastic and you know your application is 250 degrees F or less, then Redco blue may be an excellent choice for your application.

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.
