- ULTEM™ Resin For Battery Operated AR/VR Glasses
- High strength to weight ratio enables a thin wall, light weight design.
- Excellent balance of strength and resilience, in addition to light weight, offers flexibility for designers to deliver both comfort and functionality.
- High dimensional stability supports efficient assembly of electronic components.
- ULTEM™ resin’s inherent FR eliminates the need for an additional FR agent, which can cause materials, such as amorphous nylon, to be more brittle and less resilient.
- Adheres to IEC62368-1 electronic safety standards.
- ULTEM™ Photonics Applicational Benefits
- Design Freedom & Miniaturization : Thermoplastics can help enable complex part designs for pluggable and co-packaged optics to replace solutions like glass or thermoset resins. Potential applications include aspherical lenses or lens arrays.

- Product Highlight
The ULTEM™ family of amorphous thermoplastic polyetherimide (PEI) resins offer outstanding elevated thermal resistance, high strength and stiffness, and broad chemical resistance. ULTEM™ copolymers are also available for even higher heat, chemical and elasticity needs.
ULTEM™ resins uniquely balance both mechanical properties and processability, offering design engineers exceptional flexibility and freedom. ULTEM™ resins are also inherently flame retardant and possess excellent dielectric character. ULTEM™ resins are therefore an excellent candidate for your electric vehicle battery needs where high heat resistance is required.
With its appreciable flow and dimensional stability, coupled with excellent resistance to Li-ion electrolyte, ULTEM™ resins such as ULTEM™ CRS5011 resin are today being used for insulation of Li-ion cell terminals. Given its excellent dielectric character, ULTEM™ resin is also an ideal candidate for bus bar insulation. For other powertrain elements, such as DC power converters. ULTEM™ UTF120 dielectric film is already enabling high temperature film capacitors.

Technical Details & Test Data
- Lightweight Solution In AR Glasses With ULTEM™ Resin
Balance of Comfort & Performance
LLVISION wanted to develop a new generation of AR glasses that uses artificial intelligence (AI) to help individuals with hearing-loss to “see the voice” during conversation. The new product, named “LEION Hey”, was the first to be designed for consumer usage, offering an embedded 400mAh battery and eliminating the need for cables. However, the additional functionality added to the total weight of the glasses, making them potentially uncomfortable to wear on daily basis. The challenge arose to find a lightweight, flame retardant (FR), and high-performance material to reduce the total weight to less than 80 grams. The material also needed to be compliant with IEC 62368-1 electronic safety standards since the onboard computer and battery are integrated into the legs.
The Solution : High Strength ULTEM™ 1000 Resin
SABIC proposed ULTEM™ 1000 resin, a high performance, inherent FR polyetherimide (PEI) material, for consideration in the legs of LLVISION “LEION Hey” AR glasses. The high strength-toweight ratio of ULTEM™ resin helped LLVISION to address their key challenges. In addition, the excellent balance of stiffness and resilience of ULTEM™ resin provided the right clamping force, giving the end-user an overall more comfortable wearing experience. Compared to incumbent amorphous nylon solutions, the excellent dimensional stability of the ULTEM™ material supported LLVISION to create a more efficient assembly of the electronic components within the legs.
