Rotomolding Fine-Celled and Microcellular Foaming of Thermoplastics in Rotomolding Our efforts have been made to develop foaming technologies in rotomolding. Our research in this field has been very successful. The cell size uniformity has also been improved significantly. On the other hand, we have also been successful in producing 3 times and 6 times expanded PP foams with a very fine and uniform cell structure. We have developed two different rotational foam molding technologies for the production of PP foams.
Patent application based on the developed technologies is underway.
The goal of this project is to achieve microcellular structures on the order of 10 micrometer from the rotomolded PE and PP foams. Journal Publications 1. 79, ASME, NY, pp. Graduate Theses Supervised 1. Project Report, December 1996.
