應(yīng)用性能
Application performance
生物醫(yī)藥領(lǐng)域：主要作為水溶性粘合劑和干性粘合劑應(yīng)用于制粒和直接壓片技術(shù)，作為成膜材料用于薄膜包衣中，作為孔道形成物應(yīng)用于遮味劑中。應(yīng)用于糖衣防止裂片，底層包衣用于防潮。
Biomedical field: mainly used as water-soluble adhesive and dry adhesive in granulation and direct tableting technology, as film-forming material in film coating, and as pore former in masking agent. Used in sugar coating to prevent cracking, and bottom coating for moisture-proof.
日用化妝品領(lǐng)域：PVP-VA系列起著成膜劑和定型劑的作用，醋酸乙烯酯比例較高愈高，吸濕性愈低，則適合于摩絲、噴發(fā)劑和定發(fā)液。若與PVP-K30一起混合作用時(shí)，可增強(qiáng)定發(fā)效果。
Daily cosmetics field: PVP-VA series plays the role of film former and setting agent. The higher the proportion of vinyl acetate, the lower the hygroscopicity, which is suitable for mousse, spray and setting liquid. If mixed with PVP-K30, it can enhance the setting effect.
其它工業(yè)用途：可用于再濕型粘結(jié)劑，紙張用膠粘劑。作為各種油墨的增稠劑及保護(hù)性膠體。 水溶性PVP-VA64系列產(chǎn)品亦是植保劑常用的乳化劑及保護(hù)性膠體，還可作涂料的粘合劑。
