Nitrile elastomers are copolymers of acrylonitrile and butadiene. There are a number of common variations of nitrile compounds.<\/p>\n<p><strong>Acrylonitrile Content<\/strong><\/p>\n<p>The acrylonitrile (ACN) content of the polymer chains can be varied from 18% to 50%. Lower ACN content gives better low-temperature properties but poorer fuels and polar lubricants. Higher ACN content gives poorer low-temperature properties but improved fuels and polar lubricants resistance. Standard NBRs typically have 34% ACN content.<\/p>\n<p><strong>Cure system: Sulfur-cured<\/strong><\/p>\n<p>Standard Nitriles are usually sulfur-cured. Sulfur-cured compounds offer better low-temperature properties but are more prone to hardening with high temperatures. Peroxide-cured nitriles have better heat resistance and lower compression sets but are more expensive and more difficult to process.<\/p>\n<p><strong>Temperature Range:<\/strong><\/p>\n<p>Standard Low Temp: -40\u00b0C (-65\u00b0F)<br \/>Standard High Temp: 100\u00b0C (300\u00b0F)<\/p>\n","protected":false},"excerpt":{"rendered":"<p>460 X-RING<br \/>\nNITRILE 70 DUROMETER<br \/>\nLOW TEMPERATURE<br \/>\nCS: .275 IN (6.99MM)<br \/>\nID: 15.475 IN (393.07MM)<\/p>\n","protected":false},"featured_media":429611,"template":"","meta":{"_acf_changed":false,"_links_to":"","_links_to_target":""},"product_brand":[],"product_cat":[3340,3235],"product_tag":[],"class_list":{"0":"post-428898","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-x-rings","7":"product_cat-nitrile-70-duro-x-rings","8":"pa_color-black","9":"pa_durometer-181","10":"pa_material-nitrile","12":"first","13":"instock","14":"taxable","15":"shipping-taxable","16":"product-type-simple"},"acf":[],"_links":{"self":[{"href":"https:\/\/www.globaloring.com\/wp-json\/wp\/v2\/product\/428898","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.globaloring.com\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/www.globaloring.com\/wp-json\/wp\/v2\/types\/product"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.globaloring.com\/wp-json\/wp\/v2\/media\/429611"}],"wp:attachment":[{"href":"https:\/\/www.globaloring.com\/wp-json\/wp\/v2\/media?parent=428898"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/www.globaloring.com\/wp-json\/wp\/v2\/product_brand?post=428898"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/www.globaloring.com\/wp-json\/wp\/v2\/product_cat?post=428898"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/www.globaloring.com\/wp-json\/wp\/v2\/product_tag?post=428898"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
