以科技為立足之本，在全球范圍內活躍于健康、營養(yǎng)和材料領域的荷蘭皇家帝斯曼集團開發(fā)出新型耐水解PBT，為Arnite?熱塑性聚酯系列再添新產(chǎn)品。新材料將為耐高溫潮濕環(huán)境應用（包括汽車連接器、控制設備和傳感器）提供高性價比解決方案。
Royal DSM, a global science-based company active in health, nutrition and materials, is adding hydrolysis-resistant grades of polybutylene terephthalate (PBT) to its Arnite? family of thermoplastic polyesters. The new materials will provide a cost-effective solution in applications exposed to humidity and high temperatures, including automotive connectors, control devices, and sensors.
該款新型耐水解產(chǎn)品可滿足汽車市場對耐高溫高濕材料日益增長的需求，適用于尚不需使用例如帝斯曼Stanyl?PA46和ForTii?PA4T等高性能耐高溫聚酰胺材料的應用。
The new ‘HR’ grades come in response to increasing calls in the automotive market for materials that resist hot and humid environments, for applications that do not necessarily require the outstanding performance of high temperature polyamides like DSM’s Stanyl? PA46 and ForTii? PA4T products.
帝斯曼汽車電子全球市場經(jīng)理Mark Terlaak表示：“我們從客戶那里獲悉，隨著連續(xù)使用時間和發(fā)動機環(huán)境峰值溫度的持續(xù)上升，聚酰胺6、聚酰胺66和標準PBT等材料已不能滿足特定應用的要求。各級供應商將耐水解PBT視為從這些材料轉換到更昂貴的特種材料解決方案的過渡材料?！?/span>
“Our customers are telling us that with continuous-use and peak temperatures around the engine continuing to rise, materials like polyamides 6 and 66 and standard PBT are no longer good enough for the job in some applications,” says Mark Terlaak, Global Segment Leader,Automotive Electronics. “Many Tiers see HR PBT as a bridge between these materials and more expensive specialty solutions."
Terlaak還指出，PBT的性能優(yōu)于用于汽車電子應用的標準聚酰胺，因為其無需使用熱穩(wěn)定劑（某些熱穩(wěn)定劑可導致金屬接觸腐蝕問題），而且因其吸濕性較低也保證了較高的尺寸穩(wěn)定性。
Terlaak also points out that PBT scores over standard polyamides for automotive electronic applications because it does not require the use of heat stabilizers (some of which are the source of corrosion problems on metal contacts) and because its lower moisture absorption leads to higher dimensional stability.
新型Arnite耐水解PBT產(chǎn)品在諸多方面都優(yōu)于其他PBT，但其最顯著的優(yōu)勢是：在USCAR標準3、4、5類型溫度/濕度環(huán)境和雙85濕熱循環(huán)試驗（85℃和85%相對濕度）下，在長達3000小時內其機械性能具備良好的保持率。Terlaak指出，該產(chǎn)品在150℃時具有極佳的性能。他補充道：“我們的產(chǎn)品在流動性和結晶速度方面優(yōu)于幾乎所有同類產(chǎn)品，可以節(jié)約生產(chǎn)周期時間，并可在整個生命周期內保持良好的機械性能?！?/span>
The new Arnite HR grades stand out from the pack of PBTs in many ways, but most notably in their higher retention of mechanical properties after USCAR Class 3, 4, and 5 temperature/humidity profile exposure and ‘85/85’ cycles (85°C/85% relative humidity) of up to 3000 hours. Terlaak also notes that performance at 150°C is exceptional. “Our grades will outperform virtually all the competition in terms of flow, speed of crystallization – which translates into production cycle time – and mechanical property retention over the lifetime of the vehicle,” he adds.
在設定耐水解PBT系列產(chǎn)品的目標性能時，帝斯曼不僅考慮了當今汽車行業(yè)的需求，還考慮了該產(chǎn)品未來將如何發(fā)展以順應汽車行業(yè)所面臨的變革。隨著電動車和自動駕駛汽車的趨勢日益增強，該新型產(chǎn)品將面臨更高的強度測試和驗證標準。
When targeting the performance it wanted to achieve from the Arnite HR family, DSM took into consideration not only the needs of the automobile industry today, but also how they are likely to change in the future. The new grades have been engineered in anticipation of more robust testing and validation standards as the trend towards electric-powered and autonomous road vehicles picks up.
帝斯曼現(xiàn)在推出兩種30％玻纖增強的新型Arnite耐水解PBT產(chǎn)品，其中一種提升了有機硅粘性。該系列產(chǎn)品組合完善后，將涵蓋包括各種不同牌號玻纖增強型產(chǎn)品，厚度為0.4毫米時UL94防火等級高達V0的阻燃產(chǎn)品，沖擊改性產(chǎn)品，以及用以提高有機硅密封膠粘性的產(chǎn)品。
DSM is launching the new Arnite family with two 30% glass reinforced grades, one with enhanced silicone adhesion. When complete, the range will include grades with various levels of glass fiber reinforcement, flame retardant grades with UL 94 ratings of up to V-0 at thicknesses as low as 0.4 mm, impact-modified grades, and grades engineered to provide high levels of adhesion to silicone sealants.
Terlaak總結說：“該新型Arnite PBT產(chǎn)品系列的推出，鞏固了帝斯曼作為全球少數(shù)能為汽車電子應用提供全方位產(chǎn)品服務組合的塑料供應商之一的地位。
“The addition of this new Arnite PBT family strengthens our position as one of the few plastics suppliers in the world with a full-service automotive electronics portfolio,” Terlaak concludes.
