IND4汽車人：松下 - 可激光焊接的PBT材料即將量產
New laser weldable PBT compounds targeted to enhancing design flexibility and reliability of auto switches and sensors.
可激光焊接的PBT化合物將為汽車上的開關和感測器提供更好的產品設計自由度和可靠性。
In its plans to further invest in its role as an automotive supplier, Japan』s Panasonic Corp., through its Panasonic Automotive Systems Company (U.S. office in Peachtree City, Ga.) has developed PBT molding compounds for laser welding. Mass production will commence next month.
日本松下公司為了成為汽車行業的供應商拓展其未來的投資計劃，旗下的松下汽車系統公司已經研發出可激光焊接的PBT化合物。3月份將進行批量生產。
Panasonic expects these compounds will enhance the flexibility of design as well as long-term reliability of automotive switches and sensors. Based on Panasonic』s data, the new compounds boast the following features:
松下公司希望這種化合物能為汽車上的開關和感測器提供更好的產品設計自由度和可靠性。基於松下的數據，新的PBT材料具有以下優點：
1. The industry』s highest laser transmittance, which enables a high welding strength.
業內激光透光率最高，同時具有很好的焊接強度
? Laser transmittance: 72% (52% for Panasonic』s conventional PBT compounds.)
激光透光率 ：72% （松下傳統的PBT為52%）
? No air leak found under the air pressure (3 atm) in water after a high-temperature, high-humidity storage test—after 1000 hrs of exposure to 185 F and humidity of 85%; or, a temperature cycling test—temperature range of -40 F to -184F.
高溫高濕存放試驗後（185華氏度，85%的濕度），或者溫度循環試驗後（溫度範圍從-40華氏度至184華氏度），在水中3個大氣壓的情況下無空氣泄露。
2. Stable quality and performance are ensured with low warpage of molded parts, and this contributes to the enhancement of the design flexibility of automotive components.
注塑零件的翹曲很小確保產品的穩定質量和性能，這有利於汽車零部件的產品設計自由度。
? Warpage: 0.5 mm (0.02 in.) or less compared to 2.3 mm (0.091 in.) for the company』s conventional grades.
翹曲：0.5mm 以下，遠低於松下傳統的PBT材料。
3. Excellent hydrolysis resistance enables the water resistance for small-to-large
automotive components.
優異的耐水解性能，可讓大大小小的汽車零部件具背防水性能。
? High-strength retention rate after a high-temperature, high humidity storage test (as noted above): 94% vs 50% for the conventional compounds.
高溫高濕存放試驗（如上所述）後，具有很高的強度保持率：94%，而傳統材料為50%。
Currently used processing methods for the production of automotive sensors include sealing with packings and bolts, bonding with adhesive agents, as well as ultrasonic welding. Meanwhile, fast and efficient laser welding is increasingly becoming automakers』 favored assembly option, particularly since its high welding strength can shorten the bonding time and increase productivity.
當前用於生產汽車感測器的工藝方法包括用螺釘和密封件進行密封，粘接劑粘合，還有超聲波焊接。而汽車製造商越來越喜歡運用激光焊接的組裝方式，因為它快速有效，特別是它具有很高的焊接強度。因此大大縮短了粘合時間，提高了生產效率。
However, plastic molding compounds generally used for laser welding have had low laser transmittance, leading to compromised welding strength and waterproof properties. The new compounds reportedly overcome these limitations. They will showcased at two upcoming shows: The LED show, March1-3, Santa Clara, Calif.; and, Highly-Functional Material World 2016, April 6-8, 2016, Tokyo Big Sight.
然而，通常用於激光焊接的塑料成型零件的缺點是激光透光率低，導致焊接強度和防水性能上缺陷。新的PBT據報道能突破這些限制。產品將在接下來的展會上展示：3月1號至3號加州聖克拉拉的LED展，4月6號至8號東京國際展覽館的2016世界高級功能材料展。
