主要性质：本品具有高度的毛细管/水含容量，比表面大，水合能力极强，吸水作用高而迅速，吸水膨胀能力强，具有聚乙烯吡咯烷酮相同的络合能力，能络合多种物质，如酚类、碘等。20KG/纸板桶，遮光、密封，在阴凉干燥处保存。
Main properties: This product has a high capillary/water content, large specific surface area, extremely strong hydration ability, high and rapid water absorption, strong water absorption and swelling ability, and has the same complexing ability as polyvinyl pyrrolidone, and can complex with a variety of substances, such as phenols, iodine, etc. 20KG/cardboard barrel, light-proof, sealed, stored in a cool and dry place.
应用性能
PVPP产品为不溶性高分子交联聚合物，具备独特的网状性能结构，弥补了由于PVP优异的溶解性在某些方面反而被限制了的应用缺陷。且PVPP不溶于酸、碱及一般有机溶剂，而PVP则相反。 PVPP具有良好的生理安全性、吸水性、水不溶性、络合性等优良特性，在医药、食品、日用化工、饲料等领域有广阔的应用前景。
Application performance
PVPP products are insoluble high molecular cross-linked polymers with unique network performance structure, which makes up for the application defects that are limited in some aspects due to the excellent solubility of PVP. And PVPP is insoluble in acid, alkali and general organic solvents, while PVP is the opposite. PVPP has good physiological safety, water absorption, water insolubility, complexation and other excellent properties, and has broad application prospects in the fields of medicine, food, daily chemical industry, feed, etc.
生物医药领域：PVPP具有良好的生理惰性和生物相容性，以及良好的综合性能。 PVPP可用于药物崩解剂、药物缓释载体以及血液透析膜等。由于交联PVPP吸水膨胀而使片剂（胶囊）内造成很高的压力，迅速崩解成无数小颗粒，提高人体生物利用度。以各种高分子生物材料为基质的药物控制释放系统，提高了药物作用的持续性和专一性。PVPP具有良好的吸收液体的能力，能透过空气屏蔽细菌，可以吸收并释放药物，因此也可以作外伤包扎带使用。
Biomedicine field: PVPP has good physiological inertness and biocompatibility, as well as good comprehensive performance. PVPP can be used for drug disintegrants, drug sustained-release carriers and hemodialysis membranes. Due to the water absorption and expansion of cross-linked PVPP, a high pressure is created in the tablet (capsule), which quickly disintegrates into countless small particles, improving the bioavailability of the human body. The drug controlled release system based on various polymer biomaterials improves the continuity and specificity of the drug effect. PVPP has a good ability to absorb liquids, can shield bacteria through the air, can absorb and release drugs, so it can also be used as a wound dressing.
酿造和饮料工业领域：PVPP具有较强的选择吸附能力，能有效地除去植物性饮料中的花色苷和多酚，从而除去植物性饮料的非生物沉淀，保持口感和原风味，提高清晰度，改善色泽，延长保持期，因此就用于啤酒、果汁、饮料、葡萄酒等行业。
Brewing and beverage industry: PVPP has strong selective adsorption ability and can effectively remove anthocyanins and polyphenols in plant-based beverages, thereby removing non-biological precipitation in plant-based beverages, maintaining taste and original flavor, improving clarity, improving color, and extending shelf life. Therefore, it is used in beer, juice, beverage, wine and other industries.
