AI Technical Summary
The high processing temperature of existing PVC leads to large energy consumption and carbon footprint, while existing methods of cooling with additives result in poor quality, increased waste, long downtime, and low production volume.
A combination of polyvinyl butyral polymer and polyvinyl chloride resin is used, and the melt processing temperature is reduced by adding an effective amount of polyvinyl butyral polymer to the polyvinyl chloride resin.
It effectively lowers the melt processing temperature of polyvinyl chloride resin, reduces energy consumption and carbon footprint, while maintaining or improving product quality and reducing waste and downtime.
