Abstract: EVA/NBR/FR composites containing magnesium hydroxide (MH) and red phosphorus (RP) as flame retardants were prepared. Attapulgite (AT) was used to improve the mechanical properties, oil resistance, flammability, and thermal stability of the composites. It showed that upon introductiing 10 phr AT, the tensile strength and elongation at break reached 10.4 MPa and 627.1 %, respectively. The mass was increased only 3.4　% after oil immersed at 40 ℃ for 72 hours; the limited oxygen index value reached 32.2, and UL 94 level was improved from no rating to V0; the residual char was increased from 29.3 % to 35.6 % in TG at 700 ℃. The morphology of cryogenically fractured surface before and after oil immersion were observed using SEM. It was found that the fractured surfaces became more compact after the addition of AT.
