Machining ULTEM (PEI)

As we all know, PTFE (Teflon) has good insulation performance, high and low temperature resistance and wear resistance,However, PTFE is relatively soft and has low hardness, so Machining PTFE is easy to have burr.Machining PTFE is easy to deform.

So, is there a material with stronger hardness, good insulation and wear resistance? The answer is "yes." that's utlem, PEI for short.ULTEM ,The exterior is amber and translucent. It is better than PTFE (Teflon), has excellent machining performance, of course, the price will be more expensive.Generally, 10% or 30% glass fiber is added to increase hardness and wear resistance.

In the process of machining ULTEM, we found that it can be divided into three categories, ultem1000, ultem2100 and ultem2300.Ultem1000 is what we call ultem, ultem2100 is adding 10% glass fiber into ultem, and ultem2300 is adding 30% glass fiber into ultem.We call them: ultem1000 ,ultem2100 GF10%; ultem2300 GF30%.

Machining ULTEM parts, please see the picture,

It can be seen from the picture that the colors of the three parts are different. ULTEM is amber and transparent. ULTEM 2100 is close to yellow and translucent. Ultem2300 brown, opaque.In the process of machining UTLEM parts, the difficulty of machining them is,ULTEM2300>ULTEM2100>ULTEM1000.
