Effects of MPBM on Crosslinking Density and Mechanical Properties of Tetrafluoroethylene-Propylene Copolymer

Abstract:

The composites of tetrafluoroethylene-propylene copolymer (TFE-P copolymer)/N, N'-metaphenylene-bis-maleimide (MPBM)/DCP were prepared by mill. The effects of MPBM on the crosslinking density and mechanical properties of TFE-P copolymer were investigated by equilibrium swelling method, MDR rheometer and electric tensile testing machine. The results show that MPBM can efficiently increase the crosslinking density of TFE-P copolymer cured with peroxide. There is a linear relationship between MPBM and the crosslinking density while MPBM is less than 5 phr.; due to the resinification and reinforcing effect of micro-zone of MPBM resin, the crosslinking degree and the modulus of the composite increase faster while MPBM is used more than 5 phr. Perfect network and mechanical properties could be obtained by regulating the amount of MPBM in peroxide curing system.
