Various Cooling Methods to Prepare Single Polytetrafluoroethylene Composites

Abstract

Single polytetrafluoroethylene composites were prepared of cold compression molding and free sintering with various cooling conditions. The microstructure and properties of single polytetrafluoroethylene composites were investigated. The tensile and flexural properties of PTFE SPCs were investigated with various cooling conditions. The results show that The tensile strength and the tensile modulus of the samples cooling with the furnace are higher than these of the samples cooling by air, and cooling by water. The effect on flexural properties is the same to that on tensile strength. The structure of single polytetrafluoroethylene composites were analyzed by IR and SEM. It shows that cooling with the furnace is the better way for preparing of single polytetrafluoroethylene composites.
