Esses materiais s\u00e3o testados para avaliar suas propriedades de encolhimento, normalmente usados para controle de processo ou garantia de qualidade na fabrica\u00e7\u00e3o.\r\n<h3>Processo de teste<\/h3>\r\nA specimen is prepared, typically 100x100 mm, and carefully placed in a controlled temperature bath for 10 seconds to reach thermal equilibrium. During this time, the film undergoes unrestricted shrinkage. The dimensions before and after exposure are measured in both longitudinal and transverse directions. The percent shrinkage is calculated using the initial and final dimensions.\r\n<h3>Interpreta\u00e7\u00e3o do resultado do teste<\/h3>\r\nThe shrinkage percentage indicates the material's thermal response and its suitability for specific applications. Consistent shrinkage values help determine the stability and performance of the film during use.\r\n\r\n<\/div>\r\n<\/div>","link":"https:\/\/www.qualitester.com\/pt\/categoria-produto\/astm\/astm-d2732\/","name":"ASTM D2732","slug":"astm-d2732","taxonomy":"product_cat","parent":99,"meta":[],"_links":{"self":[{"href":"https:\/\/www.qualitester.com\/pt\/wp-json\/wp\/v2\/product_cat\/1044","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.qualitester.com\/pt\/wp-json\/wp\/v2\/product_cat"}],"about":[{"href":"https:\/\/www.qualitester.com\/pt\/wp-json\/wp\/v2\/taxonomies\/product_cat"}],"up":[{"embeddable":true,"href":"https:\/\/www.qualitester.com\/pt\/wp-json\/wp\/v2\/product_cat\/99"}],"wp:post_type":[{"href":"https:\/\/www.qualitester.com\/pt\/wp-json\/wp\/v2\/product?product_cat=1044"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
