Described are paint rollers formed using nucleated polypropylene and methods of making a paint roller using one or more thermoplastic components comprising nucleated polypropylene. Described are methods of making a paint roller using preformed strips or core material comprising nucleated polypropylene. The nucleated polypropylene adhesive and/or the nucleated polypropylene strips may further comprise between 5% and 66% calcium carbonate by weight. One or various levels of nucleation and/or compounds including calcium carbonate may be used to form portions of one or multiple components that make up the paint roller, including, for example, the thermoplastic strips, adhesives and/or the backing of a composite cover material. The materials can be assembled in a continuous manufacturing process. |
