汽車(chē)電子市場(chǎng)火爆,帝斯曼推新品擴(kuò)大該領(lǐng)域

以科技為立足之本,在全球范圍內(nèi)活躍于健康、營(yíng)養(yǎng)和材料領(lǐng)域的荷蘭皇家帝斯曼集團(tuán)推出應(yīng)用于薄壁電子連接器的 Akulon® PA66 Ultraflow,從而進(jìn)一步擴(kuò)大其熱塑性樹(shù)脂產(chǎn)品系列。該系列產(chǎn)品目標(biāo)應(yīng)用領(lǐng)域?yàn)槿招略庐惖钠?chē)電子市場(chǎng)。

汽車(chē)技術(shù)的創(chuàng)新90%來(lái)自于汽車(chē)電子領(lǐng)域。汽車(chē)制造商正在越來(lái)越多地采用電子部件,我們也看到汽車(chē)行業(yè)正在經(jīng)歷的一些變化如:發(fā)動(dòng)機(jī)溫度提高、更好的減震性能要求、零部件微型化、互聯(lián)網(wǎng)汽車(chē)、自動(dòng)駕駛以及向混合動(dòng)力和純電動(dòng)車(chē)轉(zhuǎn)變。這些變化對(duì)材料性能提出了新的需求,而帝斯曼也適時(shí)地加大在工程塑料產(chǎn)品組合的投入。

主要變化為:

  • 同樣或更大功率的汽車(chē)發(fā)動(dòng)機(jī)向小型化、輕量化的方向發(fā)展,往往會(huì)造成工作環(huán)境溫度升高、振動(dòng)增加甚至更加嚴(yán)重的情況;

  • 連接器、電子控制單元(ECU)等零部件的微型化趨勢(shì),要求零部件壁厚更薄、材料流動(dòng)性更好

  • 汽車(chē)OEM廠商及其供應(yīng)商更加關(guān)注對(duì)環(huán)境的影響,從而更多地采用無(wú)鹵材料

“汽車(chē)中電子和電氣部件數(shù)量不斷增加,意味著在相同甚至更小的空間內(nèi),連接器需要傳輸更多信號(hào)和更大功率。引腳密度增大和腳距減小,正在推動(dòng)對(duì)更薄壁厚和更高流動(dòng)性的連接器的需求”,帝斯曼全球汽車(chē)行業(yè)市場(chǎng)經(jīng)理Ralph Ramaekers解釋道。

Ramaekers補(bǔ)充道:“要滿(mǎn)足這些行業(yè)趨勢(shì),市場(chǎng)需要一個(gè)可以兼顧各項(xiàng)關(guān)鍵標(biāo)準(zhǔn)的材料產(chǎn)品組合。帝斯曼是世界上為數(shù)不多的能夠?yàn)槠?chē)電子應(yīng)用提供一攬子熱塑性樹(shù)脂產(chǎn)品組合的供應(yīng)商之一。其材料包括PBT、PA6、PA66、PET、PPS、PA410、PA46和PA4T,涵蓋整個(gè)產(chǎn)品性能及價(jià)格區(qū)間——我們?nèi)詫⒗^續(xù)投入,以確保我們的解決方案可以滿(mǎn)足任何市場(chǎng)需求”。

以 Akulon PA66 Ultraflow 擴(kuò)大產(chǎn)品組合

帝斯曼推出三種品級(jí)的Akulon PA66 Ultraflow樹(shù)脂,均具有優(yōu)異的流動(dòng)性、機(jī)械強(qiáng)度和斷裂伸長(zhǎng)率。

Akulon PA66 Ultraflow通過(guò)將更好的機(jī)械性能、更高的端子保持力和強(qiáng)大的結(jié)合性能相結(jié)合,進(jìn)而確保優(yōu)異的流動(dòng)性和加工性。它可滿(mǎn)足覆蓋面積更小且密度更高的連接器的要求,兼具更高的流動(dòng)性,同時(shí),由于注塑成型壓力更低,從而能減少模具的磨損和維護(hù)。更多模腔可進(jìn)一步縮短生產(chǎn)周期,降低生產(chǎn)成本以及能耗。帝斯曼將其視作可應(yīng)用于薄壁連接器、傳感器和控制單元的理想材料,并可作為間規(guī)聚苯乙烯(SPS)、聚對(duì)苯二甲酸丁二醇酯(PBT)和其他品級(jí)的PA66的替代材料。

在服務(wù)多年的電子領(lǐng)域,帝斯曼又新增了PPS和PA66產(chǎn)品系列,同時(shí)推出若干細(xì)分市場(chǎng)的產(chǎn)品,其中包括:熱傳導(dǎo)塑料;電力友好(無(wú)鹵)材料;高溫微發(fā)泡樹(shù)脂和應(yīng)用于薄壁電子產(chǎn)品的高流動(dòng)性材料。

新增的PPS為混合/高壓電機(jī)、ECU和電池組組件等應(yīng)用提供了新的解決方案。該類(lèi)樹(shù)脂尺寸穩(wěn)定性高且耐沖擊強(qiáng)度大,可抵抗長(zhǎng)期熱老化。

今年晚些時(shí)候,帝斯曼計(jì)劃推出更多新產(chǎn)品——例如全JEDEC1 HB級(jí)PA4T、PBT產(chǎn)品組合擴(kuò)展以及包括LDS(激光直接成型)在內(nèi)的若干互聯(lián)網(wǎng)汽車(chē)解決方案。

帝斯曼汽車(chē)電子電氣全球行業(yè)經(jīng)理Mark Terlaak表示:“各產(chǎn)品系列中均有專(zhuān)門(mén)的品級(jí)產(chǎn)品,以迎合不斷變化的汽車(chē)電子行業(yè)的特定發(fā)展趨勢(shì)和需求。無(wú)論是連接器、控制單元、傳感器、照明、電機(jī)還是該領(lǐng)域內(nèi)的任何其它應(yīng)用,你都可以將帝斯曼當(dāng)作你的工程塑料領(lǐng)域的一站式合作伙伴
