Polytetrafluoroethylene (PTFE) micropowders were used to prepare PTFE-oil organogel. Carbonyl iron particles were dispersed in this organogel to fabricate magnetorheological fluids. The main aim of this paper is to investigate the influences on field-induced chains by non-magnetic microstructures inside these organogel-based MRFs. https://jalyttlers.shop/product-category/log-trolley/
