摘要
A method of cooling a PVC dry blend powder in a vessel by spraying a liquified inert gas into the vessel such that the liquified inert gas contacts the powder. The PVC dry blend powder is made by mixing a powdered PVC resin with ingredients selected from the group consisting of plasticizers, stabilizers, and pigments in a mixing vessel by using a heating and mixing cycle followed by a liquified inert gas cooling cycle. The flow properties of PVC dry blend powder made by this method have an improved shelf life.
