Curing is an irreversible chemical reaction, which makes thermoset rubber products stronger and more durable. Products made of thermoset rubbers include tires, hockey pucks, circuit breakers, electrical housing, and motor components.<\/p><p>Thermoplastic elastomers (TPE) are polymers, polymer blends or compounds. They normally begin in pellet form, become liquid when heated, and can then be injected into a mold, for example. The thermoplastic takes shape as it cools and hardens. This process can be reversed by re-heating the material. TPE applications include drive belts, shock absorbers, breathing tubes, catheters, and shoe soles.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-7ab5460 e-flex e-con-boxed e-con e-parent\" data-id=\"7ab5460\" data-element_type=\"container\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t\t\t<div class=\"elementor-element elementor-element-98ac224 elementor-widget elementor-widget-heading\" data-id=\"98ac224\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t<h4 class=\"elementor-heading-title elementor-size-default\">Aplicaciones:<\/h4>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-f7f6b96 elementor-widget elementor-widget-text-editor\" data-id=\"f7f6b96\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<p>It\u00a0claims\u00a0specifications for the testing machine\u00a0system, the test specimens (including shape and size), and for the test procedure and appropriate methods to be used.
