doi:10.19491/j.issn.1001-9278.2021.06.019

Abstract

Abstract:

This paper discussed the importance of PVT characteristics and test technology and introduced the development status of PVT test technologies. A direct pressurization technique （piston?die technique） and an indirect pressurization technique （confining?fluid technique） as two traditional technologies were first introduced. The improved technologies based on traditional test techniques were further introduced， which included a high cooling speed piston?die technique， a modified confining?fluid technique and an online technology based on processing and molding equipment. The state of the art in the development of PVT equations of state for polymers was also briefly described. In addition， the problems and future research directions of PVT characterization and test techniques were summarized.

Key words: injection molding, pressure?volume?temperature characteristics, Tait equation
