Compounds containing 0, 10, 25, and 33 wt% h-BN were prepared via solution mixing to ensure uniform dispersion and subsequently vulcanized using a hot press. The materials were characterized in terms of morphology, cure behavior using a moving die rheometer (MDR), thermal conductivity, crosslink density, mechanical properties, and dynamic mechanical analysis (DMA). The incorporation of h-BN significantly enhanced thermal performance, nearly doubling the thermal conductivity at 33 wt%. MDR measurements demonstrated that this improved heat transfer capability accelerated the thermal onset of vulcanization, effectively reducing scorch time. Mechanical testing revealed a systematic increase in stiffness at application-relevant low strain levels (25\u201350%), attributed to hydrodynamic reinforcement, accompanied by a progressive increase in elongation at break. This enhanced extensibility is associated with the presence of lamellar h-BN platelets, which facilitate stress redistribution and promote dynamic chain mobility under deformation. DMA showed that h-BN incorporation increased the storage modulus and intensified the Payne effect, confirming the formation of a robust physical filler network. Overall, the incorporation of h-BN delivers a formulation pathway for energy-efficient tire curing bladders by significantly improving heat transfer efficiency and dimensional stability.<\/jats:p>","DOI":"10.3390\/polym18091112","type":"journal-article","created":{"date-parts":[[2026,4,30]],"date-time":"2026-04-30T13:32:21Z","timestamp":1777555941000},"page":"1112","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Hexagonal-Boron-Nitride-Reinforced Butyl\/Chloroprene Rubber Composites for Tire Curing Bladder Applications"],"prefix":"10.3390","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3371-7230","authenticated-orcid":false,"given":"Baran","family":"Cetin","sequence":"first","affiliation":[{"name":"Department of Polymer Science and Technology, Istanbul Technical University, 34369 Istanbul, T\u00fcrkiye"},{"name":"Brisa Bridgestone Sabanci Tyre Manufacturing and Trading Inc., 41310 Kocaeli, T\u00fcrkiye"},{"name":"TEMAG Labs, Faculty of Textile Technologies and Design, Istanbul Technical University, 34437 Istanbul, T\u00fcrkiye"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5916-9666","authenticated-orcid":false,"given":"Mehmet Durmus","family":"Calisir","sequence":"additional","affiliation":[{"name":"TEMAG Labs, Faculty of Textile Technologies and Design, Istanbul Technical University, 34437 Istanbul, T\u00fcrkiye"},{"name":"Faculty of Engineering and Architecture, Recep Tayyip Erdogan University, 53100 Rize, T\u00fcrkiye"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ali","family":"Kilic","sequence":"additional","affiliation":[{"name":"TEMAG Labs, Faculty of Textile Technologies and Design, Istanbul Technical University, 34437 Istanbul, T\u00fcrkiye"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9886-5517","authenticated-orcid":false,"given":"Islam","family":"Shyha","sequence":"additional","affiliation":[{"name":"Department of Industrial Engineering, College of Engineering, University of Business and Technology, Jeddah 21448, Saudi Arabia"},{"name":"School of Computing Engineering and the Built Environment, Edinburgh Napier University, Edinburgh EH10 5DT, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2026,4,30]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"102773","DOI":"10.1016\/j.mtcomm.2021.102773","article-title":"Effects of Silicon Carbide as a Heat Conductive Filler in Butyl Rubber for Bladder Tire Curing Applications","volume":"29","author":"Shiva","year":"2021","journal-title":"Mater.
