...idual assembly processes. It is used for joining hard and soft parts together, e.g. to attach seals or dampers directly to a part without the need for assembly or possibility of detachment. Appropriate hard thermoplastics for this process are PBT (Celanex from Ticona) and PPS (Fortron) in addition to POM. The soft components may be selected from a whole range of thermoplastic elastomers and rubbers. The actual choice of materials should be made in close consultation with the plastics manufacture...

These include Topas, as well as the so-called "MT" grades of Hostaform, Celanex, Fortron and Vectra. Each of these materials offers biocompatibility and a high resistance to chemicals and disinfecting agents, together with top-rate mechanical properties. The cycloolefin copolymer, Topas, marks a particular innovation. This is ...
