GET MORE FOR YOUR OPTICAL SENSORS WITH EXTEM™ AND ULTEM™ RESINS
A specialized series of EXTEM and ULTEM resins were developed to be well-suited for IR sensor part design and potentially contribute to lower production cost. These near IR transparent thermoplastics have multiple benefits over glass and thermosets. Compared to other thermoplastics the EXTEM RH resin series has the extraordinary potential to withstand the high temperatures of reflow soldering.
To collimate the light, these resins can be molded into a wide variety of free form optical lens designs. Versus glass, they enable the integration of multiple lenses and other parts, and are easily scalable, with cost-efficient production using multi cavity micro molding.
More complex part designs compared to alternative solutions like glass or thermosets.
Easy integration of mechanical and optical features to simplify design and assembly for potential cost improvement.
Injection molding of thermoplastics can enable high precision manufacturing of complex parts at very large volumes.
ACHIEVE EXCELLENT LIGHT TRANSMITTANCE FOR YOUR SENSOR LENSES
ULTEM™ and EXTEM™ RH resins series show excellent light transmission of over 85% for near infrared optical sensing.
In addition, anti-reflection coatings (ARC) can help reduce first surface reflection losses, improve contrast and boost the transmission to over 95%. This can enable a higher sensitivity for optical sensors or lower signal losses for fiber optical connectors.

GET DESIGN SUPPORT FOR YOUR REFRACTIVE AND DIFFRACTIVE OPTICS
Increased sensor functionality and complexity do require free form optics, for both refractive and diffractive lenses.
SABIC offers injection molding support and can assist with evaluating global micro molders that have proven capabilities to produce ULTEM™ and EXTEM™ resin components.
Validation tools and multipoint datasets are available for reliability testing, simulation and mold flow analysis. Often JEDEC reflow soldering at 260°C is required during the sensor assembly process and EXTEM RH series do offer the unique capability to withstand this high temperature.
ULTEM and EXTEM resins are well-suited for refractive optics
ULTEM and EXTEM resins offer more design freedom than epoxy and typically allow for the elimination of the time-consuming curing step.
Compared to using glass, expensive polish and grinding steps can be avoided. SABIC’s Specialties Business offers support in mold design and processing of our broad portfolio of thermoplastics.
ULTEM and EXTEM resins can be used for diffractive optics
SABIC offers support in various processing technologies for pattern replication, like injection (compression) molding, hot embossing and rapid heat/cool molding. We also offer metrology of surface patterns.
TAILOR LIGHT TRANSMISSION AND CUT OFF WAVELENGTHS
The ability to cut off the transmission of a specific wavelength of light can help reduce stray light and improve the accuracy of the sensor application.
The standard transmission values of ULTEM™ and EXTEM™ resins can be altered through special additives.
For example, transmission can be tailored to a specific value, UV-VIS can be blocked and even full opacification is possible when desired.
ULTEM and EXTEM RH resins are compatible with all common assembly technologies
SABIC has worked with industrial adhesive suppliers. We can assist in the selection of adhesives with high bonding strength against several substrates.
