PVDF聚偏氟乙烯
PVDF,英文缩写poly(vinylidene fluoride),主要是指偏氟乙烯均聚物或者偏氟乙烯与其他少量含氟乙烯基单体的共聚物,它兼具氟树脂和通用树脂的特性,除具有良好的耐化学腐蚀性、耐高温性、耐氧化性、耐候性、耐射线辐射性能外,还具有压电性、介电性、热电性等特殊性能,是含氟塑料中产量名列第二位的大产品,年产能超过4.3万吨。化学结构中以氟一碳化合键结合,这种具有短键性质的结构与氢离子形成zui稳定zui牢固的结合.因而氟碳涂料具有特异的物理化学性能,不但有很强的耐磨性和抗冲击性能,而且在严酷与恶劣的环境中有很高的抗褪色性与抗紫外线性能。本公司 可以免费提供各种材料物性及各种材质认证 如:SGS UL MSDS ROHS MDS 等证明 : 通过这些链接您能够访问供应商资料。我们尽量保证 准确数据资料; UL 黄卡含有 UL 验证的易燃性和电气特性物性说明PVDF转移膜
PVDF是一种高强度、耐腐蚀的物质,通常是用来制造水管的。PVDF膜可以结合蛋白质,而且可以分离小片段的蛋白质,zui初是将它用于蛋白质的序列测定,因为硝酸纤维素膜在Edman试剂中会降解,所以就寻找了PVDF作为替代品,虽然PVDF膜结合蛋白的效率没有硝酸纤维素膜高,但由于它的稳定、耐腐蚀使它成为蛋白测序理想的用品,一直沿用至今。PVDF膜与硝酸纤维素膜一样,可以进行各种染色和化学发光检测,也有很广的适用范围。这种PVDF膜,灵敏度、分辨率和蛋白亲和力在精细工艺下比常规的膜都要高,非常适合于低分子量蛋白的检测。但是使用PVDF膜前,一定要先用无水甲醇预处理,再在transfer buffer中平衡好才可以使用(PVDF膜用甲醇泡的目的是为了活化PVDF膜上面的正电基团,使它更容易跟带负电的蛋白质结合)。经过预处理的PVDF膜在转膜时,可以使用不含甲醇的transfer buffer。而使用NC膜时,有的需要用无水甲醇处理,有的则不必,直接用transfer buffer平衡好就可以了。磷酸铁锂电池的溶解PVDF(聚偏氟乙烯)时用丙酮效果不好1、PVDF具有优良的耐化学腐蚀性、优良的耐高温色变性和耐氧化性。2、PVDF具有优良的耐磨性、柔韧性、很高的抗涨强度和耐冲击性强度。3、PVDF具有优良的耐紫外线和高能辐射性。4、PVDF亲水性较差。5、可射出及押出之氟化树脂(俗称热可塑性铁氟龙)。6、耐热性佳并有高介电强度

产品说明 | ||||
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. | ||||
