Polypropylene (PP), also known as polypropene, is a long-chain polymer formed by the polymerization of propylene monomers. It is a thermoplastic polymer with good resistance to most solvents, acids, and bases, low water absorption, as well as good fatigue resistance and impact resistance. PP has a relatively low density, with a specific gravity of only […]<\/p>\n","protected":false},"author":1,"featured_media":385,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[6],"tags":[19],"class_list":["post-384","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-polypropylene","tag-pp"],"jetpack_featured_media_url":"https:\/\/juyuans.com\/wp-content\/uploads\/2024\/01\/PPR.jpg","_links":{"self":[{"href":"https:\/\/juyuans.com\/vi\/wp-json\/wp\/v2\/posts\/384","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/juyuans.com\/vi\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/juyuans.com\/vi\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/juyuans.com\/vi\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/juyuans.com\/vi\/wp-json\/wp\/v2\/comments?post=384"}],"version-history":[{"count":0,"href":"https:\/\/juyuans.com\/vi\/wp-json\/wp\/v2\/posts\/384\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/juyuans.com\/vi\/wp-json\/wp\/v2\/media\/385"}],"wp:attachment":[{"href":"https:\/\/juyuans.com\/vi\/wp-json\/wp\/v2\/media?parent=384"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/juyuans.com\/vi\/wp-json\/wp\/v2\/categories?post=384"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/juyuans.com\/vi\/wp-json\/wp\/v2\/tags?post=384"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
