Dotmar is at the forefront of all segments of the transport industry with our range of engineering plastics, polyurethane and moulded plastic products. The demands inherent in today's transport designs are evident across all segments of the industry.
Whether its rail, road, air or sea, all are dealing with the same concerns - excessive wear, weight reduction, vibration, friction, hot and cold environments, harsh operating conditions, heavy loading and a strong requirement to make every cent count.
The experience and expertise Dotmar has gained in developing solutions for one segment of the industry provides us with a foundation for developing solutions across other segments.
Dotmar Engineering Plastics can assist in reducing costs and lead times when compared to traditional engineering materials such as brass, sintered bronze stainless steel. Plastic rod such as Acetal (Ertacetal), Nylon (Ertalon), UHMWPE (Polystone), PETP (Ertalyte) make an excellent choice for self-lubricating plastic part.
Dotmar specialises in manufacturing custom bearings and bushes for all forms of transportation. High performance plastic is the ideal replacement for traditional brass bushes providing vastly improved wear resistance. We can also provide replacement window panels Acrylic for buses or security shields Polycarbonate for Buses, taxi's and earthmoving equipment.

Dotmar Plastics has used its in-depth knowledge of plastics, processing and design to help the rail industry achieve improved cost efficiencies, longer life, and more reliable operation. We offer thermoplastic solutions to all segments of the rail industry. The demands inherent in locomotive design are also inherent in freight and transit truck design.

The anti-roll-bar is supported by an Ertalyte TX bush, assembled into a housing. The bush, which was previously made from Bronze, must sustain very heavy loads; up to 15 tonnes (dynamic load for short periods of time).
Most modern passenger vehicles now employ secondary air suspension equipment, also known as air springs. The car body levitates on a set of rubber air chambers or bags, two being arranged on each bogie bolster. Overall, zero risk of parts breaking of the protector, or "exploding", is expected: danger of traveller injury or damage to objects/property in the vicinity needs to be overcome.
To build railway tracks, it is necessary to transport and assemble the steel rails on the actual rail track. The new rails are mainly between 80 to 102 meters long, but can also extend up to 400 meters. For transportation the rails are loaded onto wagons in layers; one wagon typically holding several layers. For the actual installation of the track, the steel rails are unloaded one by one, and put on the railway track in the right position, while the wagon moves at very low speed, then finally fixed to the rail track crossing bars.
Bayblend ® FR 3030 is a flame retardant thermoplastic polymer blend based on PC and ABS. It is noted, in particularly, for its favourable combination of mechanical and thermal properties as well as its excellent thermoforming behaviour. It is classified as "halogen-free"Ł under the terms of DIN/VDE 0472, part 815. Bayblend FR 3030 meets most local European standards for mass transportation.
Applications are based on high impact resistance, high heat deflection temperature and halogen free fire behaviour of several rail grades. Flame retardant Bayloy ® FR is used to produce seats and Bayblend sheets are used for wall cladding, ceilings, air conducts and seat backs. They can be produced with UV-protection or PVDF top layer. Typical applications for Makrolon sheets are light diffusers, luggage racks, wall-and door partitions. Laminates with glass offer possibilities for windscreens.
If you are building, designing or maintaining a Boat or Ship, our range of marine sheet products will accommodate any outdoor marine application that requires a high quality UV Polymer marine product.
If you are looking for a particular part for your marine project, our machine shops are fully equipped to both design and machine to your specific requirements. Our marine products are made from the highest quality polymers and have been manufactured in the US. Don't take the chance with inferior Asian imported plastic that may buckle and fade over time your boat is worth more than that!

POLYSTONE FENDER is an environmentally friendly rubber and timber alternative used for marine and harbour construction. POLYSTONE FENDER is a unique, low friction UHMWPE combining the benefits of high wear resistance with lower maintenance costs.
It will not rot, split or crack and is fully resistant to infestation from marine borers. POLYSTONE FENDER has a low coefficient of friction, superior impact resistance and excellent UV stability.
Use for harbour construction:
Aeroplanes must be very light-weight, fuel-efficient, but at the same time mechanically stable and perfectly safe. Additionally, every airline wants to increase its fleet's performance and minimise maintenance times. Constructors therefore must develop aeroplanes that are long reliable even at high stress. We support these constructors with our materials. We offer a great selection of thermoplastic and composites suitable for these demanding conditions. They will help you in construction of light-weight, safe and long-lived aircraft.
