Study on the factors influencing the properties and cell structure of highly foamed polyvinyl chloride materials
Highly foamed polyvinyl chloride material was prepared by one-step chemical foaming molding method.The effects of foaming agent,crosslinking agent,activation initiator,and modifier dos-age on the properties and cell structure of foamed materials were studied.The effect of the type and a-mount of foam nucleating agent on the foaming performance was discussed.The cell structure of the foamed materials in the presence of different foam nucleating agents was observed and analyzed.
