<span>PA6</span>又名尼龍<span>6</span>,是半透明或不透明乳白色粒子,具有熱塑性、輕質(zhì)、韌性好、耐化學(xué)品和耐久性好等特性,一般用于汽車零部件、機(jī)械部件、電子電器產(chǎn)品、工程配件等產(chǎn)品。<span></span>

產(chǎn)品時(shí)要充分考慮這一點(diǎn)。為了提高<span>PA6</span>的機(jī)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<span></span>

<span>PA66 </span>在聚酰胺材料中有較高的熔點(diǎn)。它是一種半晶體<span>-</span>晶體材料。<span>PA66 </span>在較高溫度也能保持較強(qiáng)的強(qiáng)度和剛度。<span> PA66 </span>在成型后仍然具有吸濕性,其程度主要取決于材料的組成、壁厚以及環(huán)境條件。在產(chǎn)品設(shè)計(jì)時(shí),一定要考 慮吸濕性對(duì)幾何穩(wěn)定性的影響。<span></span>

<span>PA66 </span>的粘性較低,因此流動(dòng)性很好(但不如<span> PA6</span>)。這個(gè)性質(zhì)可以用來加工很薄的元件。 它的粘度對(duì)溫度變化很敏感。<span>PA66 </span>的收縮率在<span> 1%~2%</span>之間,加入玻璃纖維添加劑可以將收縮率降低到<span> 0.2%~1% </span>。收縮率在流程方向和與流程方向相垂直方向上的相異是較大的。<span></span>
