一 聚苯醚PPE
聚苯醚化學名稱為聚2,6-二甲基-1,4-苯醚, PPE(Polypheylene ether) 或簡稱PPO( Polyphenylene Oxide)。又稱為聚亞苯基氧化物或聚苯撐醚,是一類耐高溫的熱塑性樹脂。市場上通用的主要為改性的聚苯醚(Modified Polyphenylene Oxide),簡稱MPPO,或者MPPE(Modified Polypheylene ether)。由于習慣上,對聚苯醚和其改性共混聚合物都稱為PPE(美國叫法)或PPO(日本叫法),本文也采用通俗稱法:以下稱為PPE或PPO。
二、聚苯醚PPE特性 PPE是一種綜合性能優(yōu)良的熱塑性工程塑料,突出的是電絕緣性和耐水性優(yōu)異,尺寸穩(wěn)定性好。
1.介電性能居工程塑料:PPE樹脂分子結構中無強極性基團,電性能穩(wěn)定,可在 廣泛的溫度及頻率范圍內保持良好的電性能。其介電常數和介電損耗角正切是工程塑料中zui
小的,且?guī)缀醪皇軠囟取穸燃邦l率數的影響。其體積電阻率是工程塑料中zui高的。PPE的優(yōu)異電性能使其廣泛應用于生產電器產品,尤其是耐高壓的部件,如彩電的行輸出變壓器( FBT)等。
2.良好的機械性能及熱性能:PPE子鏈中,含有大量的芳香環(huán)結構,分子鏈感性較強。
樹脂的機械強度較高,耐蠕變性優(yōu)良,溫度變化影響甚小。PPE具有較高的耐熱性,玻璃化溫度高達211℃,熔點268℃。
本公司 可以免費提供各種材料物性及各種材質認證 如:SGS UL MSDS ROHS MDS 等證明 : 通過這些鏈接您能夠訪問供應商資料。我們盡量保證 準確數據資料; UL 黃卡含有 UL 驗證的易燃性和電氣特性物性說明
3.優(yōu)異的耐水性:PPE為非結晶性樹脂,在通常的溫度范圍,分子運動少,主鏈中無 大的極性基團,偶極矩不發(fā)生分極,耐水性非常好,是工程塑料中吸水率zui低的品種。在熱水中長時間浸泡其物理性能仍有很少下降。4.阻燃性良好,具有自熄性:PPE的氧指數29,為自熄材料,而高抗沖擊性聚苯乙烯的氧指數17為易燃性材料,二者合一是具中等程度的可燃性,制造阻燃等級PPE時,不需要添加鹵素的阻燃劑,加入含磷類阻燃劑即可達到UL94標準,減少對環(huán)境的污染。
5.收縮率低,尺寸穩(wěn)定性好;無毒,密度小。
6.耐介質性和耐光性:PPE對酸、堿和洗滌劑等基本不受腐蝕,在受力的情況下,礦 物油及酮類、酯類溶劑會產生應力開裂;對有機溶劑如脂肪烴、鹵代脂肪烴和芳香烴等會使之融漲和溶解。PPE弱點是耐光性差,長時間在陽光或熒光燈下使用產生變色,顏色發(fā)黃,原因是紫外線能使芳香醚的鏈結合分裂所致。而如何改善PPE的耐光性成為一個課題。
三、聚苯醚(PPE)成型工藝
PPE可通過注塑、擠出等工藝加工成各種制品:
1.注塑:柱塞式或螺桿式注塑機都能加工PPE。一般采用螺桿式注塑機,要求長徑比大于15:1,壓縮比1.7 ~4.0(一般采用2.5~3.5)。
2.擠出:PPE能在擠出機上加工成管、片、棒、塊等。采用排氣式、長徑比大的擠出機。

產品說明 | ||||
Modified polyphenylene ether (PPE), high heat resistant, 20 % glass-fiber reinforced VESTORAN X7342 is the registered trademark of the Evonik Degussa GmbH for molding compounds containing poly-2,6-dimethyl-1,4-phenylene ether as polymeric constituent (poly-phenylene ether, PPE, also referred to as PPO). As a material of amorphous structure, VESTORAN X7342 shows very small mold shrinkage. Therefore molded parts have a very low tendency to warp. Moldings of VESTORAN X7342 are dimensionally stable and hydrolysis resistant even in hot water, but are more sensitive to organic solvents than semi-crystalline plastics. VESTORAN X7342 is resistant to aqueous alkalines and acides, certain alcohols, and glycol solutions. Due to the glass-fiber reinforcement the compound combines outstanding heat deflection temperature under load with high strength and rigidity. The even smaller shrinkage compared to non-reinforced VESTORAN depends on the orientation of the glass fibers in the molded part. | ||||
