Abstract

Abstract: the importance and eight application areas of pressure-volume-temperature(PVT) testing were expatiated. And most of PVC testing techniques, including conventional techniques, improved experimental techniques are explicated in detail .Conventional technique is attributed to direct method and indirect method, improved experimental techniques include the techniques considered the effect of cooling rate and deformation, techniques based on injection molding machine and extruder and ultrasonic technology. And several PVC testing products were introduced, including PVC-100 from Germany,PVT testing system from Japan, dilatometer from USA and domestic PVC on-line testing apparatus.

Key words: injection molding, pressure-volume-temperature relationship, dilatometer, direct method, indirect method
