How to choose the right engineering plastic for industrial applications

Choosing the right plastic for an industrial application is no small task. Efficiency, equipment durability, process safety, and final cost can all be directly affected by this decision. In this article, we offer a practical guide to selecting the technical plastic most suitable according to the conditions of use and the requirements of the environment.

1. Define the working conditions

Before choosing a material, it is essential to be clear about the conditions under which it will operate:

• Will there be exposure to high or low temperatures?
• Will the material be in contact with chemicals, grease, or steam?
• Will there be friction, impact, or constant mechanical load?
• Are food contact or specific hygiene conditions required?

Each of these factors directly influences the selection of the appropriate polymer.

2. Compare key properties of the main engineering plastics

Below, we show you some of the most commonly used materials and their key characteristics:

• Nylon: High mechanical and abrasion resistance, ideal for gears, wheels and parts subject to friction.
• Acetal (POM): Excellent dimensional stability and low coefficient of friction, perfect for precision parts.
• UHMW polyethylene: High wear resistance, ideal for sliding surfaces and transport guides.
• PTFE (Teflon): Superior chemical resistance and non-stick properties, useful in valves, seals and chemical processes.
• Polyurethane: High flexibility, good elastic recovery and impact resistance, used in shock absorbers and wheels.

3. Consider the manufacturing method

Some plastics are easier to machine than others. For example, acetal and nylon are easy to mill and turn, while others require special tools or cause more wear on CNC machines.

4. Evaluate the cost-benefit

The cheapest material isn't always the most cost-effective. A more resistant or durable plastic can mean less need for maintenance, fewer failures, and less production downtime, which translates into greater long-term profitability.

5. Consult with a specialized technical provider

Having the support of an expert company like Suimtec It allows you to access not only the right materials, but also advice based on experience and knowledge from multiple industries. Adapting the material to your specific conditions makes all the difference.

Conclusion

The selection of engineering plastics should not be taken lightly. Considering factors such as temperature, friction, chemical exposure, and operating conditions is key to ensuring performance and safety. At Suimtec, we help you choose the ideal material for every need.
