摘要
An elastomer bound board material, consists of a vulcanised section and a section containing a bound filler material. The vulcanised elastomer section contains no more than 10%, preferably no more than 7% non-saturated double carbon bonds in the main chain, when in the non-saturated state. The latter make up 25-70wt%, esp 40-60wt% of the total elastomer. The filler material is in powder, fibre or platelet form, and consists of organic and inorganic substances, eg glass fibres, rock wool, carbon fibres, polymer fibres, ceramic fibres, etc. The board material has at least two connected layers (1-3), and at least one of the layers is bound by an elastomer, eg EPDM. The layers are between 100mu m and 4mm thick.
