KEY TOP FOR PERSONAL DIGITAL ASSISTANT SUPERIOR IN STROKE-PROOF INTENSITY AND TRANSPARENCY

摘要

PROBLEM TO BE SOLVED: To obtain a key top for a personal digital assistant superior in transparency, shock resistance, stroke intensity and productivity, and with thickness and weight reduced.;SOLUTION: Of the key top for a personal digital assistant made by forming a resin composition which uses polycarbonate resin (A) and glass fiber (B) as indispensable constituent, viscosity average molecular weight of polycarbonate resin (A) is from 17,000 to 20,500, and compounding volume of the glass fiber (B) is 0.1 parts by weight or more and less than 1.0 parts by weight per 100 parts by weight of the polycarbonate resin (A). As a result, the key top for a personal digital assistant has excellent transparency, shock resistance, stroke intensity and productivity. Thus it can be suitably used as the key top for a personal digital assistant which requires thickness and weight reduction.;COPYRIGHT: (C)2010,JPO&INPIT
