PVDF聚偏氟乙烯
PVDF,英文縮寫poly(vinylidene fluoride),主要是指偏氟乙烯均聚物或者偏氟乙烯與其他少量含氟乙烯基單體的共聚物,它兼具氟樹脂和通用樹脂的特性,除具有良好的耐化學腐蝕性、耐高溫性、耐氧化性、耐候性、耐射線輻射性能外,還具有壓電性、介電性、熱電性等特殊性能,是含氟塑料中產量名列第二位的大產品,年產能超過4.3萬噸。化學結構中以氟一碳化合鍵結合,這種具有短鍵性質的結構與氫離子形成zui穩定zui牢固的結合.因而氟碳涂料具有特異的物理化學性能,不但有很強的耐磨性和抗沖擊性能,而且在嚴酷與惡劣的環境中有很高的抗褪色性與抗紫外線性能。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PVDF轉移膜
PVDF是一種高強度、耐腐蝕的物質,通常是用來制造水管的。PVDF膜可以結合蛋白質,而且可以分離小片段的蛋白質,zui初是將它用于蛋白質的序列測定,因為硝酸纖維素膜在Edman試劑中會降解,所以就尋找了PVDF作為替代品,雖然PVDF膜結合蛋白的效率沒有硝酸纖維素膜高,但由于它的穩定、耐腐蝕使它成為蛋白測序理想的用品,一直沿用至今。PVDF膜與硝酸纖維素膜一樣,可以進行各種染色和化學發光檢測,也有很廣的適用范圍。這種PVDF膜,靈敏度、分辨率和蛋白親和力在精細工藝下比常規的膜都要高,非常適合于低分子量蛋白的檢測。但是使用PVDF膜前,一定要先用無水甲醇預處理,再在transfer buffer中平衡好才可以使用(PVDF膜用甲醇泡的目的是為了活化PVDF膜上面的正電基團,使它更容易跟帶負電的蛋白質結合)。經過預處理的PVDF膜在轉膜時,可以使用不含甲醇的transfer buffer。而使用NC膜時,有的需要用無水甲醇處理,有的則不必,直接用transfer buffer平衡好就可以了。磷酸鐵鋰電池的溶解PVDF(聚偏氟乙烯)時用丙酮效果不好1、PVDF具有優良的耐化學腐蝕性、優良的耐高溫色變性和耐氧化性。2、PVDF具有優良的耐磨性、柔韌性、很高的抗漲強度和耐沖擊性強度。3、PVDF具有優良的耐紫外線和高能輻射性。4、PVDF親水性較差。5、可射出及押出之氟化樹脂(俗稱熱可塑性鐵氟龍)。6、耐熱性佳并有高介電強度

產品說明 | ||||
Hylar® 5000 HG is a crystalline high molecular weight powder form of polyvinylidene fluoride (PVDF)specifically designed for solvent-based coatings to provide improved gloss. It forms mechanically strong and tough films that have a broad useful temperature range. These films are highly resistant to most environmental conditions including gamma radiation and are essentially transparent to ultraviolet radiation. The weathering characteristics of Hylar® 5000 HG coatings lead to excellent performance for the long term. Hylar® 5000 is available only via a licensing program that specifies the composition of Hylar® 5000 HG coatings. A properly formulated finish contains sufficient pigment to make the film totally opaque to ultraviolet radiation at the nominal one mil (0.001 inch) film thickness suggested. SAFETY Hylar® 5000 HG is stable at temperatures up to 600°F (316°C). When it is subjected to temperatures above 600°F (316°C) for extended periods of time, hydrogen fluoride (HF) begins to evolve, and at temperatures above 700°F (371°C) HF evolution becomes rapid. Hylar® 5000 HG exhibits excellent flame resistance; however, in case of fire, HF and traces of potentially toxic fluorocarbons can be formed. HF is corrosive, causes burns on contact, and has an American Conference Governmental Industrial Hygienists (ACGIH) Threshold Limit Value (TLV-TWA) of 3 ppm (2.5 mg/m3) (1984). Thermal decomposition of Hylar® 5000 HG to HF can also occur in a bake oven in the event that temperatures are not controlled properly. In the event of fire, use NIOSH approved self-contained breathing apparatus and skin protection to protect against volatile decomposition products. Hylar® 5000 HG can be disposed of in an approved land fill, but should not be incinerated unless permitted by applicable law and provision is made for absorption of HF. | ||||
