| description | Prepn. of an air heated surface from rubber and/or tyre granulates as well as a casting resin comprises inserting a perforated plastic pipe into the above mass, hardening, opt. with moulding, and connecting to a hot air blower. The casting resin is a polyurethane prepd. from polyethers or polyesters and condensed MDI or toluenediisocyanate or a bisphenol A/epichlorohydrin polyepoxide. Problems with conventional heating e.g., electrical resistance - or hot water heating due to poor termal conductivity of both granulate and casting resin are obviated with the above system. The system may be used for road covering compsns., sport grounds etc. |
