Resin technology is evolving to meet the innovative needs of the electronics market.

Eastman Chemical offers an array of high-temperature resistant, easily processed Thermx LCP, PCT and PET engineering resins. These resins are designed to meet the requirements of surface mount technology and manufacturing trends toward higher contact densities, thinner-walled connectors, as well as greater demand for reduced cycle times.

Glass-fibre reinforced Thermx PCT polyesters, available in flame-retardant and non-flame retardant grades, offer superior physical and mechanical properties, even in extremely thin-walled parts. Their low plate-out permits extended production runs without mold disassembly for cleaning.

EastaStat PETG copolyester GSP11 is ideal for hard disk drive component packaging and similar applications. It is a thermoformable, washable, inherently static-dissipative polymer with low out-gassing.

EastaStat PETG GS21 is a clear antistatic PETG for one-way electronic packaging for computer/electronic parts. This thermoformable polymer has a surface resistivity of 104 ohms/square at 50 percent relative humidity.

GE Plastics has launched its new Visualfx resin portfolio to fill the growing demand for unique or special effect qualities in electronic and consumer products.

As part of the Visualfx line, Lexan Light Diffusion resin both transmits and reflects light into products through a unique translucent material that creates internal shadows and illuminates surfaces.

The new light diffuser resins were developed using a proprietary technology. By changing the concentration of the diffuser additive, a designer may opt to allow interesting parts to be seen while hiding other internal parts. Tint and color can also be added.

Another special effects resin from GE, Lexan Intrigue, provides a color-shifting effect which produces a 3D illusion through the technology called angular metamerism. Shifting tones of color are produced when the material’s layered construction causes the interference of light waves.

Bayer Corporation’s PC/ABS Bayblend FR (fire retardant) resin is widely used in consumer electronic applications, including housings for computer monitors, CPUs and monitors, such as Sony Electronics’ Trinitron Multiscan 17es II monitor.
