Using public transport is an important contribution to the protection of our environment. To make train trips more attractive for passengers, an intact rail network and working trains have to be the rule, not the exception. Railway technology therefore requires durable components that meet high quality requirements, including the fire protection standards EN 45545 or NFPA 130. Our motion plastics meet these demands, and are furthermore lubrication-free, which minimises maintenance effort and costs. This factor is not insignificant if train trips are to be attractive in terms of price too.
