PE - Polyethylenes | Materials

The polyolefins (mainly polyethylenes) dominate the market for rotationally molded parts. There are several reasons why this situation has arisen. One is that this material is readily converted from granules to the powder form needed for rotational molding. Another is that polyethylene remains more stable than most plastics during the relatively long heating period. Currently, polyethylene, in its many forms, represents about 85% to 95% of all polymers that are rotationally molded. PVC plastisols are quite widely used and polycarbonate, nylon, polypropylene, unsaturated polyesters, ABS, acrylics, cellulosics, epoxies, fluorocarbons, phenolics, polybutylenes, polystyrenes, polyurethanes and silicones make up the rest.
