EPDM has very high resistance to UV, ozone and weathering. Neoprene offers a good compromise between mechanical strength and weather resistance.  <\/p>\n\n<\/div>\n<\/div>\n<div id=\"faq-question-1778482452405\" class=\"rank-math-list-item\">\n<h3 class=\"rank-math-question \">What technical rubber is suitable for contact with oil?<\/h3>\n<div class=\"rank-math-answer \">\n\n<p>For contact with oils and petroleum products, NBR is the standard. For higher temperatures or aggressive chemical environments, FPM is used. <\/p>\n\n<\/div>\n<\/div>\n<div id=\"faq-question-1778482495093\" class=\"rank-math-list-item\">\n<h3 class=\"rank-math-question \">Can technical rubber be used for food contact?<\/h3>\n<div class=\"rank-math-answer \">\n\n<p>Yes, selected types of rubbers are FDA approved and can therefore be used in direct contact with food or, for example, in the pharmaceutical industry. In the food industry, silicone is most commonly used. <\/p>\n\n<\/div>\n<\/div>\n<div id=\"faq-question-1778482625577\" class=\"rank-math-list-item\">\n<h3 class=\"rank-math-question \">Which rubber has the best elasticity?<\/h3>\n<div class=\"rank-math-answer \">\n\n<p>NR natural rubber rubbers, called paragums, have the highest elasticity. They have a ductility of up to 900% and are therefore the ideal choice for mechanically stressed parts and anti-vibration elements.  <\/p>\n\n<\/div>\n<\/div>\n<div id=\"faq-question-1778482733681\" class=\"rank-math-list-item\">\n<h3 class=\"rank-math-question \">What if the technical rubber is poorly chosen?<\/h3>\n<div class=\"rank-math-answer \">\n\n<p>If the type of rubber is inappropriately chosen, the material will lose elasticity, crack or chemically degrade after a relatively short period of use. Some swelling or other deformations occur, leading to loss of functionality of the part. <\/p>\n\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<h2 class=\"wp-block-heading\">Summary<\/h2>\n\n<p class=\"wp-block-paragraph\">There are many types and variants of technical rubbers, which differ significantly from each other. The correct choice of material is crucial for the correct functionality of the part. For this reason, it is always necessary to assess the specific application and select the material that best suits the requirements.    <\/p>\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n<p class=\"wp-block-paragraph\">Pot\u0159ebujete poradit s v\u00fdb\u011brem technick\u00e9 pry\u017ee?
