Nitrile elastomers are copolymers of acrylonitrile and butadiene. There are a number of common variations of<br \/>\n\tnitrile compounds.\n<\/p>\n<p>\n\t<strong>Acrylonitrile Content<\/strong>\n<\/p>\n<p>\n\tThe acrylonitrile (ACN) content of the polymer chains can be varied from 18% to 50%. Lower ACN content gives better low-temperature properties but poorer<br \/>\n\tfuels and polar lubricants. Higher ACN content gives poorer low-temperature properties but improved fuels and polar lubricants resistance. Standard NBRs<br \/>\n\ttypically have 34% ACN content.\n<\/p>\n<p>\n\t<strong>Cure system: Sulfur-cured<\/strong>\n<\/p>\n<p>\n\tStandard Nitriles are usually sulfur-cured. Sulfur-cured compounds offer better low-temperature properties but are more prone to hardening with high<br \/>\n\ttemperatures. Peroxide-cured nitriles have better heat resistance and lower compression sets but are more expensive and more difficult to process.\n<\/p>\n<p>\n\t<strong>Temperature Range:<\/strong>\n<\/p>\n<p>\n\tStandard Low Temp: -40\u00b0C (-40\u00b0F)<br \/>\n\t<br \/>\n\tStandard High Temp: 100\u00b0C (212\u00b0F)<\/p>\n","protected":false},"excerpt":{"rendered":"<p>430 CONTOURED BACKUP RING<br \/>\nNITRILE 90 DUROMETER<br \/>\nCS: 0.236 IN (5.99 MM)<br \/>\nID: 5.176 IN (131.47 MM)<\/p>\n","protected":false},"featured_media":197477,"template":"","meta":{"_acf_changed":false,"_links_to":"","_links_to_target":""},"product_brand":[],"product_cat":[3339,3234],"product_tag":[],"class_list":{"0":"post-129808","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-back-up-rings","7":"product_cat-nitrile-90-duro-back-up-rings","8":"pa_color-black","9":"pa_durometer-594","10":"pa_material-nitrile","12":"first","13":"instock","14":"taxable","15":"shipping-taxable","16":"purchasable","17":"product-type-simple"},"acf":[],"_links":{"self":[{"href":"https:\/\/www.globaloring.com\/wp-json\/wp\/v2\/product\/129808","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\/197477"}],"wp:attachment":[{"href":"https:\/\/www.globaloring.com\/wp-json\/wp\/v2\/media?parent=129808"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/www.globaloring.com\/wp-json\/wp\/v2\/product_brand?post=129808"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/www.globaloring.com\/wp-json\/wp\/v2\/product_cat?post=129808"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/www.globaloring.com\/wp-json\/wp\/v2\/product_tag?post=129808"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
