Self-lubricating plastics are materials that have lubrication as an integral component, eliminating the need for external oil and grease. They are made from tribologically-optimized polymer blends, which are tested rigorously to ensure they last longer and perform better than metal. Self-lubricating plastics are placed into two categories: those that self-lubricate naturally and those that need additives. These plastics are used in industrial equipment to prevent friction-induced wear and tear, ensuring clean, maintenance-free operations in tough environments. They are also chemical-resistant and can withstand high temperatures, making them useful in manufacturing processes with stringent quality standards, such as in the food sector.

What You'll Learn
Self-Lubricating Plastic Bearings
Lubrication in plastic bearings is produced in two ways:
- Smearing Systems: A soft lubricating material is wiped onto the surface of the bearing, creating a layer of lubricant. The lubricant is not transmitted during mating, reducing wear and tear on the bearing and shaft.
- Debris Systems: These systems are made from materials embedded with lubricant particles or debris. The materials have low friction, but debris migrates over time. Debris materials are more inexpensive than smearing systems.
Benefits of self-lubricating plastic bearings
- Less Maintenance: Self-lubricating plastic requires less maintenance and is always in a lubricated state, protecting them from damage.
- Cost-effective: The bearing’s plastic eliminates the extra cost of oiling and greasing, reducing the operational cost of bearings and the maintenance cost of the overall product.
- High Load Capacity: Compared to other traditional bearings, self-lubricated plastic bearings can handle heavy loads.
- Chemical Resistance: The lubricants embedded in these bearings can resist harmful chemicals.

Tribologically-Optimized Polymer Blends
Self-lubricating plastics are an ingenious innovation, offering a range of benefits across various industries. These plastics are prized for their ability to lower a part's coefficient of friction, reducing the energy required for movement and minimizing wear on mechanical parts. This not only improves equipment efficiency but also leads to substantial cost savings by reducing maintenance needs and extending equipment lifespan.
One company at the forefront of self-lubricating plastics is igus®, whose products are made from tribologically-optimized polymer blends. Tribology is a scientific field that focuses on the design, friction, wear, and lubrication of interacting surfaces in relative motion. The polymer blends engineered by igus® consist of three key components: base materials, reinforcing fibers, and solid lubricants.
The base polymers form the foundation of the material, providing essential characteristics such as wear resistance and the ability to withstand high loads. These base materials are chosen for their durability and strength, ensuring that the final product can endure challenging conditions.
Reinforcing fibers are added to enhance the structural integrity of the plastic. These fibers provide additional strength, making the material capable of withstanding high forces without failing. This feature is particularly advantageous in industrial settings where equipment is subjected to significant stress and pressure.
Solid lubricants are the key differentiator in self-lubricating plastics. Unlike traditional materials that require external lubrication with oils or grease, these plastics have lubrication built-in. The solid lubricants eliminate the need for frequent re-lubrication, reducing maintenance requirements and associated downtime.
The combination of these three elements creates a superior material that outperforms metal in many applications. The tribologically-optimized polymer blends are rigorously tested to ensure they last longer and offer improved performance. Additionally, these plastics are maintenance-free, lighter than metal, and resistant to dirt, dust, and chemicals, making them ideal for a wide range of industries, including food processing, where they help meet stringent quality standards and hygiene requirements.

Natural Self-Lubrication vs Additives
Self-lubricating plastics are typically categorised into two types: those that self-lubricate naturally and those that require additives. Some resins naturally have low coefficients of friction, while others are base resins to which different additives are added to make them self-lubricating. These additives are incorporated during the manufacturing process to reduce the coefficient of friction. This helps raise their wear resistance, make them more slippery, and extend their useful life.
Some examples of naturally self-lubricating plastics include Teflon Delrin AF, Tivar 88, Tivar 1000, Tivar ESD, and Nyloil. These materials have low coefficients of friction, allowing them to reduce friction and facilitate sliding naturally.
On the other hand, additives such as waxes or Teflon-based composites can be added to plastics that do not naturally self-lubricate. These additives are usually added to the base resins during the manufacturing process. For instance, Ertalyte® TX, a plastic designed for direct contact with food, contains a lubrication additive that helps reduce friction. Another example is TIVAR® HPV, a plastic designed for the food industry, which contains a dry lubricant additive that reduces the coefficient of friction by up to 80%.
Both naturally self-lubricating plastics and those with additives offer unique benefits. Naturally self-lubricating plastics may have inherent advantages such as superior mechanical properties or higher resistance to wear and corrosion. On the other hand, additives can be tailored to specific applications, such as food-grade plastics, and can provide a significant reduction in friction, resulting in lower maintenance requirements over the lifetime of the product.

Food Safety and Hygiene Standards
Self-lubricating plastics are an important asset in the food industry. They are made of a material that allows them to function without the use of external lubricants like grease or oil. This makes them more suitable than standard materials in highly demanding applications. Self-lubricating plastics are a range of polymers that contain lubrication additives. These additives allow the plastic to lubricate itself through its movement without needing an external agent.
Nylon is another food-safe plastic that is FDA-compliant as it does not leach chemicals into food when cooking. It is commonly used for cooking utensils like spatulas, whisks, and tongs. Additionally, bioplastics are considered safe for food storage, although they may contain low levels of BPA.
Food-grade lubricants are also essential in the food production process. These lubricants are considered safe for incidental contact with items consumed by humans or animals, provided they do not exceed a certain concentration. Food-safe ratings are defined by NSF International, an independent body that sets certification standards for industrial products used in food manufacturing.
In summary, self-lubricating plastics offer significant advantages in the food industry by reducing friction and maintenance requirements. Meanwhile, food safety and hygiene standards dictate the use of specific plastics and lubricants to ensure the safe storage and production of food items.

Cost-Effectiveness and Maintenance
Self-lubricating plastics are a cost-effective solution for a variety of industrial applications. They are produced from special polymer blends, which are rigorously tested to ensure they last longer and perform better than metal components. The use of self-lubricating plastics can help to reduce maintenance costs and improve equipment efficiency.
One of the key advantages of self-lubricating plastics is their ability to remain lubricated throughout their lifetime. This is achieved through two main methods: smearing systems and debris systems. Smearing systems involve wiping a soft lubricating material onto the surface of the bearing, creating a layer of lubricant that helps reduce wear and tear. Debris systems, on the other hand, embed lubricant particles or debris directly into the material. While debris systems have the disadvantage of lubricant migration over time, they are more cost-effective than smearing systems.
The use of self-lubricating plastics eliminates the need for external lubrication, such as oiling and greasing, which can add to operational costs. This makes self-lubricating plastics a more cost-effective solution, particularly in applications where excessive friction is a concern. Self-lubricating plastics also offer superior performance in tough environments, ensuring clean, maintenance-free operation.
In addition to their cost-effectiveness, self-lubricating plastics offer a range of other benefits. They are lightweight, chemical-resistant, and able to withstand high temperatures. They also have a high load capacity, making them suitable for handling heavy loads. A careful assessment of the specific application is necessary to identify the most suitable material, as each type of self-lubricating plastic has unique features and properties.
Overall, self-lubricating plastics offer a cost-effective and low-maintenance solution for a wide range of industrial applications. By reducing the need for external lubrication and extending the useful life of equipment, self-lubricating plastics can help improve efficiency and reduce operational costs.
