Effects of Ablative Fillers on EPDM Ablative Insulation

Non-asbestos short organic fibers and inorganic materials are introduced as ablative fillers for EPDM ablative insulation.Effects of ablative fillers on mechanical and ablative properties of EPDM ablative insulation are investigated. The dispersion of ablative fillers and the relative physical properties of EPDM ablative insulation with the fillers are also analyzed. Experimental results show that in order to obtain balanced mechanical properties, the weight content of ablative fillers should be controlled and the usage of non-asbestos short organic fibers could greatly improve ablative properties,which has low density and good heat insulation.
