PEEK and ULTEM are both high-performance thermoplastics used when standard plastics cannot provide enough heat resistance, dimensional stability, mechanical performance, or electrical reliability. They can both be CNC milled, turned, drilled, reamed, and finished into precision parts, but they do not behave the same way during machining or in service. PEEK is a semi-crystalline polyetheretherketone…
UHMW vs ULTEM is not a simple ‘good versus better’ comparison. UHMW-PE is usually chosen when low friction, abrasion resistance, impact toughness, quiet sliding, and economical wear performance matter most. ULTEM is SABIC’s trade name for a family of polyetherimide (PEI) resins; PEI stock shapes are typically selected when stiffness, heat resistance, dielectric performance, and…
ULTEM machining is the CNC milling, turning, drilling and finishing of polyetherimide (PEI) stock into precision functional parts. ULTEM is SABIC’s trade name for a family of amorphous PEI resins; the family includes unfilled and reinforced grades that differ substantially in stiffness, tool wear, surface behavior and dimensional response. For buyers, the practical question is…
What Is Ultem 1000? Ultem 1000 is an unreinforced, amorphous polyetherimide (PEI) engineering thermoplastic from the ULTEM™ resin family. It is best known for combining elevated-temperature performance, inherent flame resistance, electrical insulation, mechanical strength and dimensional stability in one lightweight material. Natural stock is typically transparent to translucent amber, which also makes the material easy…
Ultem is the best-known trade name for polyetherimide (PEI), a high-performance amorphous thermoplastic used when ordinary plastics do not provide enough heat resistance, stiffness, flame performance or dimensional stability. In its natural unfilled form, PEI is typically translucent amber. Glass-reinforced and specialty grades are also available for applications that need higher stiffness, lower thermal expansion,…
UHMW-PE can be CNC milled, turned, drilled and routed successfully, but it does not behave like aluminum, steel or even a stiffer engineering plastic such as acetal. The main machining risks are elastic deflection, heat-related dimensional change, long stringy chips, burr or “fuzz” formation and post-machining movement. A reliable process therefore depends on sharp cutting…
Torlon® machining is a specialized form of high-performance polymer machining. Buyers usually reach this topic with a practical question: can a machine shop produce accurate Torlon PAI parts without creating distortion, burrs, damaged threads, dimensional drift, or avoidable material scrap? The answer is yes, but Torlon should not be treated like nylon, acetal, or a…
G10 machining looks straightforward until the cutting tool actually enters the material. Unlike aluminum or conventional engineering plastics, G10 is a glass-fabric-reinforced epoxy laminate. Its combination of woven glass reinforcement and thermoset resin gives the material useful mechanical strength, electrical insulation, moisture resistance and dimensional stability, but the same glass reinforcement that makes G10 useful…
Polycarbonate can be CNC milled, turned, drilled, routed, threaded, and polished with good results, but heat, chip evacuation, residual stress, clamping pressure, and chemical compatibility must be controlled. Sharp tools and a correct chip load are more important than copying one fixed RPM from the internet. Polycarbonate (PC) is a strong, transparent engineering thermoplastic that…
Nylon (polyamide, PA) is widely used for CNC-machined gears, bushings, rollers, wear pads, guides, insulators and other functional components because it combines low density, wear resistance, useful fatigue performance and relatively low friction. It is also easy to underestimate. Compared with metals, nylon has lower stiffness, lower thermal conductivity, much higher thermal expansion and a…
