There are several kinds of plastic that can be rotationally molded. By far the most common type of plastic used in rotational molding is Polyethylene. Polyethylene accounts for more than 90% of the plastic used for rotational molding. This is due to the low price and excellent physical properties possessed by the various types of polyethylene. Polyethylene has a top continuous use temperature of about 130 degrees F. There are several types of polyethylene from which to select. |

Polypropylene |

When higher continuous use temperatures are required in the finished part, polypropylene is often the resin of choice. In many applications, polypropylene can be used up to 200+ degrees F. The one drawback to using polypropylene in rotational molding is that the finished part can be much more brittle than many other plastics. |
