LRPu or low-resilience polyurethane is a material distinguished by an "ability to slowly return to its original shape" (viscosity).〔(macworld covers LRPu )〕 The resulting impact resistance results in LRPu being used in soft laptop sleeves〔 and other lightweight cases for portable electronic equipment, as an alternative to the softer neoprene. May be related to, or be the same thing as Memory foam. == See also == *Neoprene *Polyurethane *memory foam *Sorbothane 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「LRPu」の詳細全文を読む スポンサード リンク
