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 vary from 18% to 50%. Lower ACN content gives better low-temperature properties but inferior resistance to fuels and polar lubricants. Higher ACN content gives lesser quality 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 (-40\u00b0F)<br \/>Standard High Temp: 100\u00b0C (212\u00b0F)<\/p>\n","protected":false},"excerpt":{"rendered":"<p>230 O-RING NITRILE (NBR, BUNA)<br \/>\n90 DUROMETER BLACK<br \/>\nCS: .139&#8243; (3.53MM)<br \/>\nID: 2.484&#8243; (63.09MM)<\/p>\n","protected":false},"featured_media":0,"template":"","meta":{"_acf_changed":false,"_links_to":"","_links_to_target":""},"product_brand":[],"product_cat":[3335,3228],"product_tag":[],"class_list":{"0":"post-334838","1":"product","2":"type-product","3":"status-publish","5":"product_cat-o-rings-standard-sizes","6":"product_cat-nitrile-nbr-90-duro-o-rings","7":"pa_color-black","8":"pa_durometer-594","9":"pa_material-nitrile","11":"first","12":"instock","13":"taxable","14":"shipping-taxable","15":"product-type-simple"},"acf":[],"_links":{"self":[{"href":"https:\/\/www.globaloring.com\/wp-json\/wp\/v2\/product\/334838","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:attachment":[{"href":"https:\/\/www.globaloring.com\/wp-json\/wp\/v2\/media?parent=334838"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/www.globaloring.com\/wp-json\/wp\/v2\/product_brand?post=334838"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/www.globaloring.com\/wp-json\/wp\/v2\/product_cat?post=334838"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/www.globaloring.com\/wp-json\/wp\/v2\/product_tag?post=334838"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
