SABIC launched its first high-performance extem at NPE 2018 ™ Resin infrared optical sensor lens

Saudi Basic Industries Corporation (SABIC), the world's leading diversified chemical enterprise, recently introduced a major breakthrough in the production process of infrared optical sensor lens at the American plastics and mold technology exhibition (NPE 2018, booth number: s19001). The lens uses SABIC's exem ™ Thermoplastic polyimide (TPI) resin can be used in proximity sensors and gesture recognition of intelligent and other electronic products. Soprod SA, a Swiss molding company, uses SABIC's high-performance material with high infrared light penetration characteristics to realize mass production of sensor lenses by micro molding with multi-mode tools. Compared with the grinding and polishing of quartz glass and the curing process of epoxy resin, extem ™ Resin has the advantages of high efficiency and mass molding, which can significantly improve the processing speed, ensure the stability of quality, and avoid high-cost secondary processing. This breakthrough of soprod provides a new and efficient solution for the electronic industry, which helps to meet the increasing market demand for infrared optical sensors

pitteloud said, "with extem ™ The excellent performance of the resin, when we first used thermoplastic resin for micro molding, we achieved great success. SABIC material is very suitable for mass production of small precision parts due to its high fluidity and low shrinkage. In addition, it can withstand the high temperature environment of lead-free welding commonly used in device assembly. We are happy to develop this innovative manufacturing process with the help of our long-standing expertise in the production of advanced watch movements, which undoubtedly gives us a strong competitive advantage. "

sabic global extem ™ Business manager Andy

verheijden added: "from video game controllers to UAVs, infrared optical sensors are widely shown. Bayer engineers are testing headlights made of light plastic in Shanghai polymer research and Development Center for new functions of consumer electronics products. This cooperation with soprod proves the use of extem ™ The feasibility and many advantages of producing infrared optical lenses by resin micro molding process. With this innovative process, our customers in the electronics industry can quickly produce the components needed for the real next generation of equipment. "

high infrared light penetration and high temperature resistance

extem ™ The resin can provide the key optical properties required by the infrared sensor lens, including high infrared light penetration, high refractive index, low haze and zero surface defects. EXTEM ™ The resin provides two colors: natural color and black. Black absorbs visible light but transmits infrared light, which helps to improve the accuracy of the proximity sensor

It is estimated that the exhibition area is still controlled at more than 300000 square meters.

the proximity sensor equipped with infrared transmitting lens and separating lens projects the received signal to the sensor. It can measure the friction table. If there is a software problem, you can consult our technicians about the change of surface size and the dispersion of wear on the friction surface (exem is used for both lenses) ™ Resin production)
