In the presented paper, the influence of high-energy ionizing radiation on the basic mechanical properties of the melamine resin, phenol-formaldehyde resin, and nitrile rubber blend has been studied for the first time. The mechanical properties of irradiated samples were compared to those of non-irradiated materials. It was found that radiation doses up to 150 kGy improved the mechanical properties of the tested materials in terms of a significant increase in stress at break, tensile strength, and tensile modulus at 40% strain, while decreasing the value of strain at break. At radiation doses above 150 kGy, the irradiated polymer blend is already degrading, and its tensile characteristics significantly deteriorate. An radiation dose of 150 kGy thus appears to be optimal from the viewpoint of achieving significant improvement, and the radiation treatment of the given polymeric blend by a beam of accelerated electrons is a very promising alternative to the traditional chemical mode of treatment which impacts the environment.<\/jats:p>","DOI":"10.3390\/ma11122405","type":"journal-article","created":{"date-parts":[[2018,11,28]],"date-time":"2018-11-28T11:43:44Z","timestamp":1543405424000},"page":"2405","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["The Effect of High-Energy Ionizing Radiation on the Mechanical Properties of a Melamine Resin, Phenol-Formaldehyde Resin, and Nitrile Rubber Blend"],"prefix":"10.3390","volume":"11","author":[{"given":"Ivan","family":"Kopal","sequence":"first","affiliation":[{"name":"Faculty of Industrial Technologies in P\u00fachov, Alexander Dub\u010dek University of Tren\u010d\u00edn, Ivana Krasku 491\/30, 020 01 Puchov, Slovakia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Juliana","family":"Vr\u0161kov\u00e1","sequence":"additional","affiliation":[{"name":"Faculty of Industrial Technologies in P\u00fachov, Alexander Dub\u010dek University of Tren\u010d\u00edn, Ivana Krasku 491\/30, 020 01 Puchov, Slovakia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ivan","family":"Labaj","sequence":"additional","affiliation":[{"name":"Faculty of Industrial Technologies in P\u00fachov, Alexander Dub\u010dek University of Tren\u010d\u00edn, Ivana Krasku 491\/30, 020 01 Puchov, Slovakia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Darina","family":"Ondru\u0161ov\u00e1","sequence":"additional","affiliation":[{"name":"Faculty of Industrial Technologies in P\u00fachov, Alexander Dub\u010dek University of Tren\u010d\u00edn, Ivana Krasku 491\/30, 020 01 Puchov, Slovakia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Peter","family":"Hybler","sequence":"additional","affiliation":[{"name":"Progresa Final SK, s.r.o., Ferien\u010d\u00edkov\u00e1 18, 811 08 Bratislava, Slovakia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marta","family":"Harni\u010d\u00e1rov\u00e1","sequence":"additional","affiliation":[{"name":"Faculty of Engineering, Slovak University of Agriculture in Nitra, Tr.
