To meet these requirements, many different foams of various densities are used. The foam in the cushions is either molded to the final shape or cut from existing foam stock and bonded together with adhesives. Open cell urethane foams are most commonly used with densities as low as 1.98 lb\/ft3. If the cushion is to serve as a flotation device in emergency situations, the foam must be closed cell; polyethylene foams are often used for this. <\/p>\n\n\n\n<p>Neoprene, silicone, and modified urethane foams can be used for cushions to meet FAR 25.853(c) without a fire-blocking textile. Theymay also be used as fire blockers over conventional foams. The densities of these foams have a range of 3 to 4 lb\/ft3.<\/p>\n\n\n\n<p>*\u6210\u672c\u539f\u56e0\uff0c\u5ec9\u4ef7\u822a\u7a7a\u503e\u5411\u4e8e\u51cf\u5c11\u6ce1\u6cab\u7684\u539a\u5ea6\uff0c\u589e\u52a0\u7a7a\u95f4\u3002<\/p>\n","protected":false},"excerpt":{"rendered":"<p>\u5ea7\u6905\u6ce1\u6cab\u7684\u9009\u62e9\u57fa\u4e8e\u78e8\u635f\uff0c\u8212\u9002\u6027\uff0c\u6f02\u6d6e\u6027\uff0c\u53ef\u71c3\u6027\u7b49\u8981\u6c42\u3002 \u4e3a\u4e86\u6ee1\u8db3\u8fd9\u4e9b\u8981\u6c42\uff0c\u4f7f\u7528\u4e86\u8bb8\u591a\u4e0d\u540c\u5bc6\u5ea6\u7684\u6ce1\u6cab\u3002 \u57ab\u5b50\u4e2d\u7684&hellip; <a class=\"more-link\" href=\"https:\/\/www.zuranceshi.com\/?p=1521\">Continue reading <span class=\"screen-reader-text\">\u98de\u673a\u5ea7\u6905\u7684\u6ce1\u6cab\u6750\u6599\u963b\u71c3<\/span><\/a><\/p>\n","protected":false},"author":41,"featured_media":1522,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":[],"categories":[13],"tags":[],"_links":{"self":[{"href":"https:\/\/www.zuranceshi.com\/index.php?rest_route=\/wp\/v2\/posts\/1521"}],"collection":[{"href":"https:\/\/www.zuranceshi.com\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.zuranceshi.com\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.zuranceshi.com\/index.php?rest_route=\/wp\/v2\/users\/41"}],"replies":[{"embeddable":true,"href":"https:\/\/www.zuranceshi.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=1521"}],"version-history":[{"count":1,"href":"https:\/\/www.zuranceshi.com\/index.php?rest_route=\/wp\/v2\/posts\/1521\/revisions"}],"predecessor-version":[{"id":1523,"href":"https:\/\/www.zuranceshi.com\/index.php?rest_route=\/wp\/v2\/posts\/1521\/revisions\/1523"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.zuranceshi.com\/index.php?rest_route=\/wp\/v2\/media\/1522"}],"wp:attachment":[{"href":"https:\/\/www.zuranceshi.com\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=1521"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.zuranceshi.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=1521"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.zuranceshi.com\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=1521"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
