Selvol 聚乙烯醇（PVA）是由日本积水化学工业株式会社旗下的 Sekisui Specialty Chemicals 生产的一种水溶性合成高分子材料，因其优异的成膜性、乳化性和粘合性，被广泛应用于建筑、纺织、造纸、粘合剂以及医药等多个行业。Selvol PVA 最显著的特点之一是可溶于水，这使得它成为许多石油基高分子的环保替代品。溶于水后，它可形成透明、粘稠的溶液，适合用于制作薄膜、胶粘剂或涂层。其可生物降解和无毒性的特性，进一步增强了其在食品包装和个人护理品等要求环保和安全的应用场景中的优势。Selvol 聚乙烯醇根据不同行业需求，提供多种不同等级的产品。例如，低黏度产品适用于喷涂型涂料和造纸行业的表面施胶；而高黏度产品则提供更强的粘合力和拉伸强度，适合用于纺织整理或建筑材料如墙板胶粘剂的配方中。通过调整分子量与水解度，制造商可以精确控制材料的性能，以满足不同应用的要求。在粘合剂行业中，Selvol 以其优异的粘结强度和耐水性而受到青睐，广泛用于白乳胶、书籍装订、标签和纸张复合等领域。其无溶剂、无毒的特性也非常适用于对环保要求严格的生产环境。在建筑领域，Selvol PVA 被用于水泥和砂浆中作粘结剂，提高施工性能与结构强度；在纺织制造中，它被用作上浆剂，保护纱线在织造过程中的完整性，提升生产效率。
