High Quality High Impact Polystyrene/HIPS Plastic Granules

There are two basic processes for HIPS production: intermittent process and continuous process. The two processes generally use prepolymerization first. After the completion of prepolymerization, the polymerization is continued in the form of suspension in the intermittent process and in the form of solution in the continuous process. Therefore, intermittent process is also called bulk suspension process, and continuous process is also called solution process.
