TPU材料是一種熱彈體材料,現在越來越多的被人們用來生產各種產品,還能替代大部分的PVC材料,那么在注塑加工成型過程中,TPU的縮水率影響怎么樣呢?下面小編就跟大家一起來分享一下。
首先,TPU材料吸水性還是比較大的,這樣就導致注塑過程中如果含水量較多那么縮水率就很比較大,通常TPU材料的縮水率在1.3%到1.5%之間,隨著TPU硬度的增加而減少。通常TPU材料在出廠時候含水率很低,但是如果TPU存儲環境較潮濕會導致TPU吸水含水量就會增加,這個時候如果不干燥直接拿這種含水量高的TPU材料注塑加工產品會導致產品氣泡、產生各種花紋嚴重甚至會導致制品的各項性能指標下降嚴重,所以TPU材料在加工之前需要烘干處理,溫度控制在80-100度之間,保持2個小時即可烘干。
