PITTSFIELD, MASS/ USA -- August 1, 2006 -
The keypads, housings, and other wear parts for mobile phones, computers, and digital cameras can take a real beating from constant handling. Although polycarbonate (PC) is a favorite choice for these components, until now it has been necessary to hard-coat the resin to prevent abrasion and maintain a good surface appearance. But secondary hard coating means extra cost, additional processing time, and potential environmental impact. To help solve this challenge, GE Plastics has developed a new family of Lexan* PC resins featuring outstanding scratch resistance. Compared to standard PC, GE’s Lexan DMX resins provide improved surface hardness without the need for hard coating. These materials are excellent candidates for transparent applications such as soft keys, infrared lenses, bezels, and screens.
Five-Times Higher Pencil Hardness than Standard PC
Eliminating the need for secondary coating operations can provide several important benefits to manufacturers:
Lower costs by avoiding the purchase of coating materials and equipment Reduced cycle time by cutting out a secondary processing step Less environmental impact from volatile organic compounds (VOCs) released into the atmosphere from the coating process
GE’s Lexan DMX resins are available globally. They are currently manufactured in Bergen op Zoom, the Netherlands; Mount Vernon, Indiana, the United States; and Singapore. Production will expand to Moka City, Japan, in 2006.
