GLS Corp. of McHenry, Ill., developed thermoplastic elastomers that help vision-impaired people navigate computer systems with Braille aids.
Caprock Manufacturing of Lubbock, Texas, injection molds such parts for the Freedom Scientific Blind/Low Vision Group of St. Petersburg, Fla. A thumb wheel and bezel for Freedom's Focus line are examples of using a material that is soft but with good grip, to make using computers easier. Caprock overmolds Dynaflex TPE based on Kraton to make the parts in Nissei and Toshiba injection presses.
