The top 5 durable plastics<\/h1>\n
\n

<\/p>\n

When you have\u00a0plastic made to measure, it is important to select plastic material with the right properties for your application. A material property which is frequently required is wear resistance.<\/p>\n

Durable plastics<\/h2>\n\n\n\n

Wear resistance can be put into two categories: durability and robustness. Or to be more precise: low friction combined with a long lifespan, which is important for bearings, for example. Wear-resistant plastics have several advantages over metal or bronze equivalents, such as high dynamic load capacity, good dry-running properties, weight, chemical resistance, and cost price. <\/p>\n\n\n\n

The top 5 wear-resistant plastics and their characteristics are listed below.<\/p>\n\n\n\n

1. Polyamide (PA)<\/h2>\n\n\n\n

Polyamide (PA)<\/a>, also known as nylon, is one of the most commonly used wear-resistant plastics. It is widely used in manufacturing processes to produce wear plates, gears, and plain bearings. The material has relatively high stiffness and is ideally suited for heavy dynamic loads and offers good vibration-damping properties. Its temperature range is between -40\u00b0 and +100\u00b0C. Furthermore, polyamide does not age quickly, and most grades are resistant to high temperatures.<\/p>\n\n\n\n

Because PA is available in many grades with specific additives, it is a highly versatile material suitable for a wide variety of applications. In the semiconductor industry, PA is frequently used in mechanical components that combine dynamic loads with the requirement for low particle shedding. The most commonly used grades are: PA6G, PA6 MoS\u2082, PA12, glass-filled PA (PA6 GF30), carbon-filled PA (PA6 CF20), and oil-filled PA.<\/p>\n<\/div>\n\n\n\n

2. HMPE (Werkstoff-S)<\/h2>\n\n\n\n

High-Molecular-Weight Polyethylene (HMPE)<\/a> is widely used in the food industry. This wear-resistant material, which has a relatively low coefficient of friction, can be supplied with a food safety certificate and is therefore safe for use in processes where it comes into direct contact with food.<\/p>\n\n\n\n

Furthermore, unlike PA\/Nylon, for example, HMPE does not absorb moisture. When using it, however, care must be taken to ensure that friction does not cause temperatures to rise too high (<80\u00b0C).<\/p>\n\n\n\n

There are several variants of HMPE, including HMPE-500 and 1000. The latter is well known under the brand name \u201cWerkstof-S\u201d and is even more wear-resistant than HMPE 500. It can therefore be used even under the most demanding conditions and at extremely low temperatures down to -200\u00b0C. Furthermore, HMPE-1000 allows virtually no other materials to adhere to it. In addition to the food industry, HMPE is used in guide components where low friction and minimal particle generation are critical, such as in cleanroom environments.<\/p>\n\n\n\n

3. POM<\/h2>\n\n\n\n

Like Nylon or polyamide, POM<\/a> is a widely used, wear-resistant plastic. The material is also known as Delrin and Polyacetal. POM is much less wear-resistant than Nylon and Arnite, which means it is mainly used for manufacturing high-precision parts which do not have to undergo high stress. <\/p>\n\n\n\n

POM is lightweight, dimensionally stable, does not discolour, and is well-suited for making accurate parts. However, it has limited wear resistance, so this material should ideally be seen as a normal construction plastic. The most commonly used POM variants are:<\/p>\n\n\n\n
