| Abstract: |
| The effect of acrylonitrile content of nitrile rubber（NBR） on the properties of NBR/polyvinyl
chloride（PVC） foamed materials was investigated. The results showed that at the same accelerator amount
used，the vulcanization and foaming compatibility of NBR/PVC compounds with different acrylonitrile
contents in NBR and the physical properties of the foaming materials varied greatly. By adjusting the amount
of the accelerator，the vulcanization and foaming compatibility of NBR/PVC compounds were improved to
prepare foaming materials with low apparent density，low vacuum water absorption，low thermal conductivity
and good compression resilience. |
