CNC Machined Ultem Parts

Furthermore, always providing exceptional CNC Machined Plastic Parts through 27 years of Experience in Plastic production. Most notably, having the ability to accomplish tight tolerances. Further, having a great depth of knowledge when, CNC Milling and Turning the huge variety of Plastic Materials available today. And, because Sentinel works solely with Plastic, we have a focus that gives us an edge over many of our competitors in the industry.

Where Is Ultem Used

Notably, being hydrolysis resistant and highly resistant to acidic solutions, and can tolerate repeated autoclaving cycles, such as with repeated steam sterilization of reusable medical devices. Thus, Ultem ® is widely used in electronics because of its good arc resistance and dielectric constant. Therefore, other typical applications include analytical instrumentation and structural Components that require high strength and rigidity at elevated temperatures.

Key Properties – Ultem
LONG-TERM HEAT RESISTANCE – Ultem

Importantly, Ultem has excellent stability of physical and mechanical properties, So, at elevated temperatures thanks to high Glass transition temperature of 217 °C. Also, available with relative thermal indices (RTI) up to 180 °C

STRENGTH AND STIFFNESS

Also, Ultem has outstanding strength and amorphous thermoplastic among the available alternatives. furthermore, predictable stiffness and strength up to 200 °C. Furthermore, Transparent grades are equal in strength to other thermoplastics with opacifying fillers.

DIMENSIONAL STABILITY

Certainly, one of the most dimensionally stable thermoplastics available, offering predictability over a wide temperature range. While also, filled grades offer exceptionally high-tolerance dimensional capabilities.

ENVIRONMENTAL STRESS & CRACKING RESISTANCE

Moreover, unlike most other amorphous thermoplastics, Ultem Machining resins retain strength and resist stress cracking when exposed to automotive and aircraft fluids, aliphatic hydrocarbons, alcohols, acids, and weak aqueous solutions.

FLAMMABILITY, SMOKE GENERATION AND TOXICITY

Also, Inherent flame resistance without additives in most grades, I.E. exceptionally difficult to ignite. Plus, a limiting oxygen index (LOI) of 47%, meeting UL94 V0 specifications in sections as thin as 0.41 mm. Furthermore, generating extremely low smoke per the NBS smoke evolution test, with products of combustion no more toxic than those of wood. PROCESSABILITY Above all, Ultem can be CNC Machined, Turned & Milled, to a high-Quality standard.

Ultem Machining – CNC Milling

Importantly, Sentinel has eight Plastic CNC Milling Machines. All of which, can produce almost any cut shape from the extensive range of Industrial Plastics available in today’s market, Including Ultem Plastic Having cutting tables, which can take large Sheet sizes up to a maximum of 3000mm x 2000mm and Materials ranging from 1mm up to 50mm in thickness. Our top brand name Machines can achieve high standard finishes and sizes every time.

Ultem Machining – CNC Turning

Plastic CNC Turning at Sentinel Plastics

Importantly, Sentinel has four plastic CNC turning lathes. All can produce almost any turned or milled shape from the extensive range of industrial engineering plastics available in today’s market — including Ultem machining.

Our top-brand name machines can achieve high-standard finishes and precise sizes every time. Ultimately, our experienced team at Sentinel has many years of expertise and knowledge in machining exceptional quality plastic parts for various industries, including medical, subsea, and power control.

Standard Shapes and Forms

Sheet: .040” – 4” thick
Rod: .187” – 8” diameter
The range of sizes and shapes are grade specific.

Grades

Ultem® 1000

Ultem® 1000 is the standard, unfilled grade of Ultem®. It is resistant to UV and gamma radiation and performs especially well in hot air and water environments. It retains 85% of its tensile strength after 10,000 hours of immersion in boiling water, and 100% of its tensile strength after 2,000 cycles in a steam autoclave at 270°.

Ultem® 1000 is FDA and USP Class VI compliant, and USDA and NSF approved. The standard colour is amber.

Ultem® 2300

Ultem® 2300 is a 30% glass-reinforced grade of Ultem®. The addition of glass fibre provides greater tensile strength and rigidity, while also improving dimensional stability. The standard colours are tan and green.

In Conclusion

Sentinel Plastics Ltd is versatile, experienced, and flexible — always aiming to be as helpful as possible. If it’s plastic cutting (not molding or extruding), there's a good chance we can help.
