Dotmar Engineering Plastics offer tailored solutions to address the key challenges faced by trucks and buses in maximising payload capacity and minimising maintenance. By leveraging lightweight materials with superior wear resistance compared to traditional options like steel, Dotmar enables significant weight reduction while ensuring durability in components exposed to constant wear and friction, such as bearings, bushes, and wear pads.

One of the critical issues in trucking is carry back, the leftover material sticking to the truck's lining. Dotmar's Matrox Linings provide an effective solution, reducing carry back by up to 20%, thereby ensuring maximum productivity for each and every load.

For moving components like turn-tables and fifth wheels, Dotmar's engineering plastics such as Polystone 7000 AST and Polystone Ultra offer a compelling alternative to steel. With their low coefficient of friction, these plastics provide a slippery surface, facilitating smoother pivoting for trailers and improving manoeuvrability on the road.

In addition to these specialised applications, Dotmar's engineering plastics find diverse uses in truck and bus equipment. For instance, Nylon tarp Bo Rods offer flexibility combined with sufficient stiffness to support the weight of the tarp, ensuring reliable performance in various weather conditions, and loading scenarios.

Dotmar Engineering Plastics offers indispensable solutions for the marine industry, addressing the unique challenges posed by saltwater exposure, UV radiation, corrosion, and wear.

In the harsh marine environment, where saltwater can wreak havoc on components, materials must exhibit exceptional resistance to corrosion, erosion, and wear. Dotmar's engineering plastics excel in meeting these demands, offering unparalleled durability and longevity.

One critical concern in marine applications is galvanic corrosion, caused by electrolysis in saltwater. Dotmar's high-density polyethylene (HDPE) serves as an effective insulator, preventing galvanic corrosion of vital marine components like engine mounts, thus ensuring their reliability and longevity.

Additionally, wear and abrasion components such as ball bearings for pulleys, stern shaft bearings, and rudder bearings benefit greatly from the superior properties of engineering plastics like Ertalyte. These materials, with their high strength and resistance to water absorption, offer durability and reliability even in harsh marine conditions where salt, sand, and grit are prevalent.

Dotmar's materials, such as Polystone PG100 (HDPE), revolutionise conventional hull construction for boat manufacturers. Offering superior impact resistance and abrasion tolerance, Polystone PG100 ensures extended service life and reduced maintenance requirements for marine vessels especially when compared to traditional materials such as aluminium and fibreglass. Its positive buoyancy enhances stability, while its resistance to corrosion, electrolysis, and UV radiation ensures long-term reliability. Furthermore, its fouling resistance minimises maintenance efforts, while its ability to undergo in-situ repairs without the need for hot works ensures continuous operation with minimal downtime.

Dotmar Engineering Plastics plays a crucial role in servicing the rail industry by providing tailored solutions that address the unique challenges faced by train carriage manufacturers and track maintenance teams. For carriage makers, Dotmar's focus lies in supplying mechanical parts with exceptional wear and abrasion resistance, such as bushes and wear pads, aimed at reducing maintenance frequency and prolonging the lifespan of components. By replacing metal-on-metal contact with engineered plastics, Dotmar not only eliminates the need for grease and lubricants but also contributes to weight reduction, thus increasing payload capacity and operational efficiency. Moreover, some of  Dotmar's range of engineering plastics serve as electrical insulators and isolators, reducing conductivity and offering significant weight savings compared to metal clamps, particularly when utilising materials like Polyethylene. Additionally, Dotmar provides materials compliant with standards like EN45545-2 for fire retardancy and anti-static properties, ensuring safety and reliability in rail applications.

In railway track maintenance, Dotmar's HDPE Polystone 300 H-pads play a vital role in enhancing track performance and longevity. By replacing metal track pads with HDPE H-pads, Dotmar reduces noise levels, improves vibration dampening, and minimises abrasive erosion of concrete sleepers. These H-pads also offer UV resistance, preventing deterioration due to exposure to sunlight, and are immune to rotting and corrosion, ensuring long-term reliability. Additionally, Dotmar's HDPE Polystone 300 turnout plates provide low friction and high wear resistance, essential characteristics for turnout plates to maintain smooth operation over time.
