品名:聚酰胺6或尼龍6(PA6)性狀:半透明或不透明乳白色結(jié)晶形聚合物 特性:熱塑性、輕質(zhì)、韌性好、耐化學品和耐久性好
特性:PA6的化學物理特性和PA66很相似,然而,它的熔點較低,而且工藝溫度范圍很寬。它的抗沖擊性和抗 溶解性比PA66要好,但吸濕性也更強。因為塑件的許多品質(zhì)特性都要受到吸濕性的影響,因此使用PA6設(shè)計產(chǎn)品時要充分考慮這一點。為了提高PA6的機械特性,經(jīng)常加入各種各樣的改性劑。玻璃纖維就是常見的 添加劑,有時為了提高抗沖擊性還加入合成橡膠,如EPDM和SBR等。對于沒有添加劑的產(chǎn)品,PA6的收縮 1%到1.5%之間。加入玻璃纖維添加劑可以使收縮率降低到0.3%(但和流程相垂直的方向還要稍高一些)。Wellman offers a variety of compounds which include Lubricated grades for improved mold release. Nucleation for reducing mold shrinkage and cycle time, and Heat Stabilized grades for reduced oxidation at elevated temperatures.
應用范圍:工業(yè)生產(chǎn)中泛用于制造軸承、圓齒輪、凸輪、傘齒輪、各種滾子、滑輪、泵葉輪、風扇葉片、蝸輪、推進器、螺釘、螺母、墊片、高壓密封圈、耐油密封墊片、耐油容器、外殼、軟管、電纜護套、剪切機滑輪套、牛頭刨床滑塊、、電磁分配閥座、冷陳設(shè)備、襯墊、軸承保持架、汽車和拖拉機上各種輸油管、活塞、繩索、傳動皮帶,紡織機械工業(yè)設(shè)備零霧料,以及日用品和包裝薄膜等。
