Finishing of rotational molding grade resin |
摘要 |
Rotational mold grade resin is made by subjecting polyolefin to the following process: (1) polyolefin granules are blended with additives to form a masterblend; (2) the masterblend is intensively mixed with additional resin granules to shape the granules, reduce particle size and disperse additives; (3) the intermixed material is cooled and (4) large particles are removed and recycled.
