El poli(alcohol vin\u00edlico) (PVA) es un pol\u00edmero sint\u00e9tico hidrosoluble derivado de la hidr\u00f3lisis del poli(acetato de vinilo). Es conocido por sus propiedades film\u00f3genas, su biocompatibilidad y su elevada resistencia a la tracci\u00f3n. El PVA se utiliza ampliamente en la producci\u00f3n de textiles, papel y adhesivos debido a sus excelentes caracter\u00edsticas adhesivas y emulsionantes. Su solubilidad en agua y biodegradabilidad lo convierten en un material preferido en diversas aplicaciones industriales, como las pel\u00edculas de envasado y los productos sanitarios.<\/p>","protected":false},"featured_media":3912,"comment_status":"closed","ping_status":"closed","template":"","meta":[],"product_brand":[],"product_cat":[25],"product_tag":[],"class_list":{"0":"post-3874","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-ploymers","8":"first","9":"instock","10":"shipping-taxable","11":"product-type-simple"},"_links":{"self":[{"href":"https:\/\/chemneo.com\/es\/wp-json\/wp\/v2\/product\/3874","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/chemneo.com\/es\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/chemneo.com\/es\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/chemneo.com\/es\/wp-json\/wp\/v2\/comments?post=3874"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/chemneo.com\/es\/wp-json\/wp\/v2\/media\/3912"}],"wp:attachment":[{"href":"https:\/\/chemneo.com\/es\/wp-json\/wp\/v2\/media?parent=3874"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/chemneo.com\/es\/wp-json\/wp\/v2\/product_brand?post=3874"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/chemneo.com\/es\/wp-json\/wp\/v2\/product_cat?post=3874"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/chemneo.com\/es\/wp-json\/wp\/v2\/product_tag?post=3874"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
