瓦克化學(xué)推出有機(jī)硅彈性體，可生產(chǎn)薄如人頭發(fā)絲功能膜

慕尼黑，2014年11月19日—總部位于慕尼黑的瓦克化學(xué)集團(tuán)將在美國環(huán)境發(fā)電與能源儲(chǔ)存會(huì)議（Energy Harvesting & Storage USA）上展出高純有機(jī)硅精密薄膜。這種ELASTOSIL^?Film品牌的薄膜以卷裝形式供貨，厚度自20微米起。該產(chǎn)品進(jìn)一步拓展了有機(jī)硅的應(yīng)用范圍，可用來實(shí)現(xiàn)新型產(chǎn)品設(shè)想與方案，用于功能性隔膜、醫(yī)療電子元件，以及以電活性聚合物為基礎(chǔ)的傳感器、執(zhí)行器與發(fā)電機(jī)等新型技術(shù)。本年度美國環(huán)境發(fā)電與能源儲(chǔ)存會(huì)議于11月19-20日在美國加利福尼亞州圣克拉拉舉行。

Precision silicone film:ELASTOSIL? Film from the Munich-based chemical group WACKER is thinner thanhuman hair. The film is manufactured under cleanroom conditions and has excellentdielectric properties. Potential applications include functional membranes andinnovative technologies based on electroactive polymers (EAPs).

由于市場之前尚無以此種形式銷售的有機(jī)硅精密薄膜，瓦克推出的ELASTOSIL^?Film產(chǎn)品填補(bǔ)了這一空白。這種薄膜完全由有機(jī)硅彈性體制成，以卷裝形式供貨，厚度自20微米起。ELASTOSIL^?Film在潔凈室條件下生產(chǎn)，且不添加任何溶劑。為便于使用，制成后的有機(jī)硅薄膜被置于中間載體，以保障剝膜時(shí)，薄膜完好無損。

ELASTOSIL? Film is a precision silicone film that has not yet been made commercially available in this form. It is made entirely from silicone elastomers and is available as roll stock in thicknesses down to 20 microns. ELASTOSIL? Film is manufactured in cleanroom conditions without the use of solvents. For improved handling, it comes with an intermediate backing which can be peeled off easily without damaging the product.

瓦克的這一獲得專利保護(hù)的生產(chǎn)工藝能夠根據(jù)預(yù)設(shè)厚度，制成無缺陷、且極為均勻的連續(xù)膜，薄膜帶在整個(gè)寬度和長度上的厚度偏差，不超過額定值的±5%。該材料的上述品質(zhì)及其典型的有機(jī)硅特性，可使一些至今無法或極難實(shí)現(xiàn)工業(yè)化生產(chǎn)的技術(shù)應(yīng)用成為可能。

WACKER’s patent-registered production process provides immaculate and extremely uniform continuous-feed films with a defined thickness. It deviates from the specification by +/- 5 percent at most across the entire width and length of the film web. This particular property, together with the material’s typical silicone characteristics, permits technical applications that were previously very hard or even impossible to implement on an industrial scale.

ELASTOSIL^aFilm可用作隔膜、透汽性包裝及保護(hù)膜等，也可用來積聚瓦斯。在此，有機(jī)硅薄膜充分利用了有機(jī)硅彈性體不透水，但能夠使水汽以及氧氣、氮?dú)饣蚨趸嫉葰怏w透過的特性。

ELASTOSIL? Film is suitable as a gas-permeable packaging and protective film or as a membrane for separating or enriching gases. In this regard, silicone films exhibit a beneficial property typical of silicone elastomers: the film is permeable to water vapor and certain gases such as oxygen, nitrogen and carbon dioxide, but not to water.

由于有機(jī)硅彈性體擁有電氣絕緣性能和良好的介電性能，并能夠幾乎毫無損傷地承受長時(shí)間機(jī)械負(fù)荷，因此，ELASTOSIL^aFilm也可用作電活性聚合物（EAP），能夠在一定的條件下，通過施加電壓改變EAP的形狀，模擬直線運(yùn)動(dòng)，甚至自然運(yùn)動(dòng)形式。因而，這種有機(jī)硅薄膜能夠依據(jù)“人造肌肉”原理，用于新型傳感器、執(zhí)行器和發(fā)電機(jī)的開發(fā)，也可應(yīng)用于電子消費(fèi)品、繼電器、閥門、泵、假肢等眾多領(lǐng)域。

Silicone elastomers are electrically insulating, have good dielectric properties, and endure long-term mechanical loads with hardly any signs of fatigue. Therefore, ELASTOSIL? Film can also be used as an electroactive polymer (EAP). Under certain conditions, EAPs are able to alter their shape when electrical voltage is applied. Thus, they are able to replicate linear and natural forms of movement. Based on this principle of an artificial muscle, silicon films can be used to design novel kinds of sensors, actuators, and generators. Possible applications range from consumer electronics, electrical relays, valves and pumps to artificial limbs.

ELASTOSIL^?Film有機(jī)硅薄膜同樣能夠在未來將海浪轉(zhuǎn)化為電能的技術(shù)中起到關(guān)鍵性作用。在一個(gè)由德國聯(lián)邦教育和科研部（BMBF）資助的項(xiàng)目中，以羅伯特·博世有限公司（Robert Bosch GmbH）為首的工業(yè)界與科研界聯(lián)盟正在進(jìn)行未來海浪能發(fā)電廠的基礎(chǔ)研究，瓦克是其中負(fù)責(zé)研發(fā)有機(jī)硅薄膜及生產(chǎn)工藝的項(xiàng)目合作者。

In the future, silicone films may also play a pivotal role in the conversion of maritime wave power into electricity. As part of a project sponsored by the German Federal Ministry of Education and Research (BMBF), a consortium of industrial and R&D partners led by Robert Bosch GmbH is developing the basic principles underlying future wave farms. WACKER is the project member responsible for developing silicone films and the related production process.

ELASTOSIL^?Film能夠?yàn)槲磥硇蛣?chuàng)新及技術(shù)的工業(yè)化應(yīng)用做出關(guān)鍵性貢獻(xiàn)。這種薄膜可靠的功能性及其優(yōu)異的耐久性可使關(guān)鍵元件的使用幾乎不需要任何維護(hù)或保養(yǎng)。

ELASTOSIL? Film provides the key to the commercialization of innovative designs and technologies. The films ensure precise functioning. Thanks to their durability, they also make sure that critical components enjoy almost maintenance-free operating.
