Plate size: 1320 x 800 x 7 mm / activation time 2 1/2 min. / cooling time approx. 5 min. With the previous one. conventional care of children with paralysis caused by cerebral palsy, thermoplastic HD-PP or PE sheets offer excellent stability. however lacking it on any upholstery. A certain level of comfort can only be achieved by grinding out edge area; these edges then become razor-sharp. This problem arose the idea for a new sandwich variant made of 2 different EVA materials: SANDWICH? OT ONE This product combines the required level of stability (outside: EVA approx. 70 Shore A) in the Image combined with an inner padding (inside: EVA approx. 25 Shore A) Additional advantages : 1. Residual comfort due to lower hardness - compared to the above-mentioned PP or PE panels 2. Extremely thin grinding is therefore not necessary - also due to the material properties no razor-sharp edges can develop here. 3. Rivets - which are required to attach closure elements - are not lying on the surface. but go so far into the material OT ONE. that to the skin no disturbing contact points can arise
