Vespel 是杜邦公司生產(chǎn)的一系列耐用高性能聚酰亞胺基塑料的商標(biāo)。
特點(diǎn)和應(yīng)用
Vespel 主要用于航空航天、半導(dǎo)體和運(yùn)輸技術(shù)。它結(jié)合了耐熱性、潤(rùn)滑性、尺寸穩(wěn)定性、耐化學(xué)性和抗蠕變性,可用于惡劣和 的環(huán)境條件。
與大多數(shù)塑料不同,即使在高溫下也不會(huì)產(chǎn)生明顯的釋氣,這使得它可用于輕質(zhì)隔熱罩和坩堝支撐。它在真空應(yīng)用中也表現(xiàn)良好,低至極低的低溫。然而,Vespel 往往會(huì)吸收少量的水,從而導(dǎo)致放置在真空中的泵時(shí)間更長(zhǎng)。
盡管在這些特性中,有些聚合物都超過(guò)了聚酰亞胺,但它們的結(jié)合是 Vespel 的主要優(yōu)勢(shì)。
熱物理性質(zhì)
Vespel 通常用作測(cè)試熱絕緣體的導(dǎo)熱性參考材料,因?yàn)樗哂懈咴佻F(xiàn)性和熱物理性能的一致性。例如,它可以承受高達(dá) 300 °C 的反復(fù)加熱,而不會(huì)改變其熱性能和機(jī)械性能。已經(jīng)發(fā)布了大量測(cè)量的熱擴(kuò)散率、比熱容和推導(dǎo)密度的表格,這些表格都是溫度的函數(shù)。
磁性
Vespel 用于 NMR 波譜的高分辨率探針,因?yàn)樗捏w積磁化率(Vespel SP-1 在 21.8 °C 時(shí)為 -9.02 ± 0.25×10?6[5])接近室溫下的水(20 °C 時(shí)為 -9.03×10?6 [6]) 負(fù)值表示兩種物質(zhì)都是抗磁性的.將NMR樣品周圍材料的體積磁化率與溶劑的體積磁化率相匹配,可以減少磁共振線的磁化率展寬。
制造應(yīng)用加工
Vespel 可以通過(guò)直接成型 (DF) 和等靜壓成型(基本形狀 - 板材、棒材和管材)進(jìn)行加工。對(duì)于原型數(shù)量,通常使用基本形狀以提高成本效益,因?yàn)?DF 零件的工具成本相當(dāng)高。對(duì)于大規(guī)模的CNC生產(chǎn),DF零件通常用于降低每個(gè)零件的成本,而犧牲的材料性能不如等靜壓生產(chǎn)的基本形狀。
類型
對(duì)于不同的應(yīng)用,特殊配方被混合/復(fù)合。形狀由三個(gè)標(biāo)準(zhǔn)過(guò)程生成:
壓縮成型(用于板材和環(huán));
等靜壓成型(棒材用);和
直接成型(用于大批量生產(chǎn)的小尺寸零件)。
與從壓縮成型或等靜壓形狀加工而成的零件相比,直接成型零件的性能特征較低。等靜壓形狀具有各向同性的物理性質(zhì),而直接成型和壓縮成型的形狀表現(xiàn)出各向異性的物理性質(zhì)。

Vespel is the trademark of a range of durable high-performance polyimide-based plastics made by DuPont.[1][2]
Characteristics and applications
[edit]
Vespel is mostly used in aerospace, semiconductor, and transportation technology. It combines heat resistance, lubricity, dimensional stability, chemical resistance, and creep resistance, and can be used in hostile and extreme environmental conditions.
Unlike most plastics,[3] it does not produce significant outgassing even at high temperatures, which makes it useful for lightweight heat shields and crucible support. It also performs well in vacuum applications,[4] down to extremely low cryogenic temperatures. However, Vespel tends to absorb a small amount of water, resulting in longer pump time while placed in a vacuum.
Although there are polymers surpassing polyimide in each of these properties, the combination of them is the main advantage of Vespel.
Thermophysical properties
[edit]
Vespel is commonly used as a thermal conductivity reference material for testing thermal insulators, because of high reproducibility and consistency of its thermophysical properties. For example, it can withstand repeated heating up to 300 °C without altering its thermal and mechanical properties.[citation needed] Extensive tables of measured thermal diffusivity, specific heat capacity, and derived density, all as functions of temperature, have been published.[citation needed]
Magnetic properties
[edit]
Vespel is used in high-resolution probes for NMR spectroscopy because its volume magnetic susceptibility (?9.02 ± 0.25×10?6 for Vespel SP-1 at 21.8 °C[5]) is close to that of water at room temperature (?9.03×10?6 at 20 °C [6]) Negative values indicate that both substances are diamagnetic. Matching volume magnetic susceptibilities of materials surrounding NMR sample to that of the solvent can reduce susceptibility broadening of magnetic resonance lines.
Processing for manufacturing applications
[edit]
Vespel can be processed by direct forming (DF) and isostatic molding (basic shapes – plates, rods and tubes). For prototype quantities, basic shapes are typically used for cost efficiency since tooling is quite expensive for DF parts. For large scale CNC production, DF parts are often used to reduce per part costs, at the expense of material properties which are inferior to those of isostatically produced basic shapes.[7]
Types
[edit]
For different applications, special formulations are blended/compounded. Shapes are produced by three standard processes:
compression molding (for plates and rings);
isostatic molding (for rods); and
direct forming (for small size parts produced in large volumes).
Direct-formed parts have lower performance characteristics than parts that have been machined from compression-molded or isostatic shapes. Isostatic shapes have isotropic physical properties, whereas direct formed and compression molded shapes exhibit anisotropic physical properties.
Some examples of standard polyimide compounds are:
SP-1 virgin polyimideprovides operating temperatures from cryogenic to 300 °C (570 °F), high plasma resistance, as well as a UL rating for minimal electrical and thermal conductivity. This is the unfilled base polyimide resin. It also provides high physical strength and maximal elongation, and the best electrical and thermal insulation values. Example: Vespel SP-1.15% graphite by weight, SP-21added to the base resin for increased wear resistance and reduced friction in applications such as plain bearings, thrust washers, seal rings, slide blocks and other wear applications. This compound has the best mechanical properties of the graphite-filled grades, but lower than the virgin grade. Example: Vespel SP-21.40% graphite by weight, SP-22for enhanced wear resistance, lower friction, improved dimensional stability (low coefficient of thermal expansion), and stability against oxidation. Example: Vespel SP-22.10% PTFE and 15% graphite by weight, SP-211added to the base resin for the lowest coefficient of friction over a wide range of operating conditions. It also has excellent wear resistance up to 149 °C (300 °F). Typical applications include sliding or linear bearings as well as many wear and friction uses listed above. Example: Vespel SP-211.15% moly-filled (molybdenum disulfide solid lubricant), SP-3for wear and friction resistance in vacuum and other moisture-free environments where graphite actually becomes abrasive. Typical applications include seals, plain bearings, gears, and other wear surfaces in outer space, ultra-high vacuum or dry gas applications. Example: Vespel SP-3.

推動(dòng)汽車行業(yè)的可持續(xù)發(fā)展進(jìn)步
杜邦工程師和材料科學(xué)資源正在與 各地的供應(yīng)商和制造商合作，以幫助汽車行業(yè)實(shí)現(xiàn)更好的燃油經(jīng)濟(jì)性和可持續(xù)性。
目標(biāo)是制造更省油的汽車、卡車和工業(yè)機(jī)械。我們正在共同努力，使用新材料實(shí)現(xiàn)這些目標(biāo)，并開發(fā)創(chuàng)新方法，幫助減少對(duì)化石燃料的依賴，減少汽車、卡車和機(jī)械或整體溫室氣體排放，包括所用材料的制造。
推動(dòng)持久的變革
杜邦通過(guò)多種方式與汽車制造商合作。我們支持用高性能彈性體和熱塑性塑料替換較重的金屬和其他塑料部件。杜邦材料適用于多種汽車系統(tǒng)，包括引擎蓋下和動(dòng)力總成應(yīng)用，這些應(yīng)用必須耐高溫和磨蝕性燃料和液體。
我們還擁有最廣泛的聚合物系列之一，這些聚合物使用非食品可再生資源制成，以替代石化基材料。
如何處理一氧化碳2
這是一個(gè)簡(jiǎn)單的概念：更輕的汽車需要更少的燃料，產(chǎn)生更少的一氧化碳2排放。許多汽車制造商已經(jīng)減少了一氧化碳的排放2排放是企業(yè)的首要任務(wù)。此外，一些國(guó)家還為參與排放交易的公司提供激勵(lì)措施。無(wú)論哪種情況，都要找到有助于減少一氧化碳的材料替代品2排放還可以降低成本。
減少摩擦和能量損失
杜邦™ Vespel® 零件和形狀用于減少需要高耐熱性和耐化學(xué)性的苛刻發(fā)動(dòng)機(jī)和動(dòng)力總成應(yīng)用中的磨損和摩擦。例如，自潤(rùn)滑 Vespel® 襯套可以在柴油發(fā)動(dòng)機(jī)的 EGR 閥的整個(gè)生命周期內(nèi)保持一致的性能，有助于實(shí)現(xiàn)新的排放標(biāo)準(zhǔn)。
創(chuàng)新中心
任何組織或政府都無(wú)法單獨(dú)支持汽車行業(yè)的可持續(xù)發(fā)展，因此杜邦正在通過(guò) 各地的創(chuàng)新中心與客戶、合作伙伴和政府合作。我們?cè)陧n國(guó)首爾建立了汽車創(chuàng)新中心;印度浦那;日本名古屋;瑞士日內(nèi)瓦;土耳其伊斯坦布爾;和美國(guó)密歇根州的特洛伊。
可持續(xù)性是競(jìng)爭(zhēng)優(yōu)勢(shì)
在瞬息萬(wàn)變、競(jìng)爭(zhēng)激烈的環(huán)境中，杜邦正在與材料制造商、零部件供應(yīng)商和制造商合作進(jìn)行創(chuàng)新，以幫助汽車行業(yè)實(shí)現(xiàn)更大的可持續(xù)性。我們看到了結(jié)果，從更高性能的發(fā)動(dòng)機(jī)到使用采用可再生材料的飾面的內(nèi)飾。
2011年，福特、菲亞特和豐田在塑料工程師協(xié)會(huì)的“ 創(chuàng)新性的塑料使用”頒獎(jiǎng)典禮上都獲得了獲獎(jiǎng)?wù)?。他們都與杜邦工程師合作，并使用了采用可再生來(lái)源杜邦材料的組件。杜邦可以幫助您應(yīng)對(duì)汽車行業(yè)如何通過(guò)材料選擇提高可持續(xù)性的挑戰(zhàn)，并制造消費(fèi)者、公司和政府現(xiàn)在想要和需要的汽車。
