FILLERS FOR FOAMED RIGID POLYMER PRODUCTS |
| 摘要 |
The present invention relates to a resin composition for preparing foamed rigid polymer products, comprising at least one polymer resin, a surface-treated calcium carbonate having a weight median particle diameter d50 of between 0.1 μm and 1 μm, measured according to the sedimentation method, in an amount of at least 10 parts per hundred parts of the at least one polymer resin (phr) and a blowing agent in an amount of less than 1 phr, to a foamed rigid polymer product prepared from the composition, to a method for preparing a foamed rigid polymer product as well as to the use of a calcium carbonate for reducing the density of a foamed rigid polymer product. |
