Saudi Basic Industries Corporation, the world's leading diversified chemical company, has introduced a new family of highly transparent, high-temperature, injection-moldable polycarbonate copolymer resins. LEXAN ™ CXT series resins combine high temperature resistance, high flowability, Excellent color stability under extreme molding conditions and high refractive index and other excellent performance.
LEXAN ™ CXT resins are used in a wide range of optical applications in the electronics, consumer and industrial, and medical industries. Typical products in the first two areas include lenses and small sensors for the detection of visible light; in the medical field, this resin meets market demand for excellence Optical quality and high temperature performance requirements, suitable for silicone coated transparent masks and other applications.
In recent years, the tendency to miniaturization of products has become increasingly pervasive, with vendors looking to integrate more functionality in a smaller space, pushing up the demand for high performance resins such as LEXAN ™ CXT. With its B120 test conditions up to 190 ° Vicat softening temperature of 195 ° C and glass transition temperature (Tg) of 195 ° C, the injection molded parts produced with LEXAN ™ CXT resin withstand the harsh PCB assembly processes such as low temperature reflow or wave soldering, and Can be used for prolonged exposure to high temperatures.
With a refractive index (RI) of more than 1.6 and high transparency (a 1-mm thick sample is more than 89% transparent to visible and infrared light), LEXAN ™ CXT resins create extremely small-size lenses such as cellphone cameras, , And assembled into a printed circuit board for a variety of welding operations. LEXAN ™ CXT resin excellent thermal stability can also help prevent parts deformation or discoloration.
Feedback from SABIC's customers in the development of LEXAN ™ CXT resins has also shown that the material has many other potential benefits including LEXAN ™ CXT to reduce production cycle time to increase productivity and thereby reduce system costs; increase dimensional accuracy; reduce downtime and Improve the yield; and help design and manufacture more complex geometry, larger size, thin-walled and more superior texture components.
Mr. Zhao Fa Lei, Head of SABICLEXAN ™ products, said: "The birth of LEXAN ™ CXT resin series reflects the current and future needs of SABIC's customers in various fields and can apply our innovations in resin product technology to practice. Customers address these major challenges. '
The new LEXAN ™ CXT resin will be another new member of the LEXAN ™ polycarbonate copolymer specialty resin family, which includes EXL resin with good low temperature impact resistance, transparent and opaque heat-resistant resin XHT, Strong weatherability of the SLX resin.
