Description (optional):
<p>目前用于制作智能手環、智能手表的材料基本上就是TPE、矽膠以及TPU這三種材料,那麽,TPE、TPU及矽膠哪個更適合做智能手環、智能手表?一般情況下,定位高檔的手環就采用醫用級別的TPE或TPE材料,這兩種材料不僅僅環保、無毒和無味,而且對人體不會産生傷害。</p> <p>TPE/TPU的價格遠遠高于<a href="https://www.ow.com.tw/silicone-case">矽膠手機殼</a>,醫用級別的TPE/TPU往往都是使用在醫療用品上,這和人體息息相關,甚至植入人的體內,TPE/TPU可以回收再生利用,性價比比較高。</p> <p>矽膠的彈性稍微差一些,從外觀上看,TPE/TPU可以做很透明的樣式,但是,矽膠不可以,最透的矽膠件也是比較朦胧。</p> <p><img src="https://www.ow.com.tw/wp-content/uploads/2023/09/硅膠手機殼.webp" width="800" height="502" /></p> <p><a href="https://www.ow.com.tw/silicone-case">矽膠套</a>具有良好的手感,摔在地上具有抗震性與抗沖擊性,矽膠不溶于水,具備不錯的防水性能,但是,矽膠的質感偏硬,款式少,易油膩,貼合性稍差,同時,材質稍差的矽膠還容易粘灰和進灰,相對而言,TPU具備更高的耐磨性,耐刮,彈性好,強度高,耐寒性突出,耐油,耐水,耐黴菌,柔韌性好,TPU唯一的缺點是不易脫模,生産效率相對偏低,TPE材料手感柔軟爽滑,比矽膠與TPU手感更好,良好的耐磨性,易上色,成型脫模方便,環保無毒,對人體不會産生過敏性反應,可以說,TPE是做智能手環首選的材料。</p> <p>TPU是看到的最多,用的比較廣泛,在市場上占用率較高,其主要原因是價格適合,産品耐磨性有絕對的優勢,其他材料比擬不了,但是用TPU做的手機殼時間一久會發黃,而且有的表面還有類似霜的白色粉末,就是出粉,在加工過程中不好出模,生産效率低,廢品率也是TPU致命的缺點,所以TPU做手機殼不是最好的選擇,高端的手機殼用TPU是不合適的。</p> <p><a href="https://www.ow.com.tw/silicone-case">液態矽膠手機殼</a>在手感各方面比較好,細膩柔絲般手感的確不錯,但是如果放置兜裏,出現裂紋或者破口的話,比較容易撕裂,且在工藝方面也是相當的麻煩,不能注塑成型,産量低,水口不能回收利用,所以成本相對來說要高。</p> <p>TPE手機殼相對來說還是比較合適和滿足客戶的要求的,價格會比TPU貴比矽膠便宜,其在TPU與矽膠之間,在工藝上,TPE是有絕對的優勢的,成型,效率高。</p> <p>TPE手機殼材料</p> <p>溫度使用範圍廣,高低溫使用性能優異</p> <p>如絲般的手感,爽滑,更勝于普通的彈性體</p> <p>高彈性,易于著色,易于成型,快速脫模,不粘模具</p> <p>良好的耐化學性,耐候性,耐磨性,低摩擦系數</p> <p>可以和一系列的工程塑料,如PC、ABS等組合成型,也可以單</p> <p>使用硬度範圍:50~80</p> <p>有吸震作用,吸震率7%</p>
