Description

n

Case molding material for PCBs and electronic components

n

Technomelt AS 4226 is a UV-stabilized thermal plastic material designed for molding. It is used in applications in which optical transparency is important to the functionality of the device. The low application temperatures make TECHNOMELT® AS 4226 ideal for sensitive electronic components such as sensors. The unique design of the material allows for long-term exposure to UV light with minimal change to clarity or color. This makes the material ideal for applications for in-cabin automotive sensors and industrial components.
