Fine-celled polyolefin foam materials |
摘要 |
Fine-celled polyolefin foams of high dimensional stability at elevated temperatures and high stiffness, with foam densities ranging from 10 to 600 kg/m3, consisting of mixtures of polypropylenes and polyolefins, which were reacted with bifunctional, unsaturated monomers and/or hydrolyzable, ethylenically unsaturated organosilane compounds in the presence of thermally decomposing free radical-forming agents in two reactive process steps and subsequently foamed. The fine-celled polyolefin foams are suitable for use in the packaging sector, preferably for packaging foods, for external and internal parts of motor vehicles and for components of electric and electronic equipment.
