With the continuous development of the construction, home appliances, automobile and other industries, the market demand for PVC foam board is expected to continue to grow.

[0003] The production process of PVC foam board mainly includes the steps of raw material preparation, batching and mixing, extrusion molding, cooling and shaping, surface treatment and cutting. Among them, the selection of suitable raw materials such as PVC resin, foaming agent, additives, as well as key technologies such as optimized formula design, extruder selection and debugging, and foaming process optimization are crucial to improving the quality and performance of PVC foam board.
