Engineering Plastics: Which is best for each application?

Engineering plastics play a key role in various industries thanks to their strength, versatility, and adaptability to extreme conditions. However, each type of plastic has specific properties that make it more suitable for certain applications.

Below, we explore the most widely used engineering plastics and their primary uses in industry.

Nylon (PA6 and PA66)

This material stands out for its high mechanical resistance, its ability to absorb impacts and its thermal stability, withstanding temperatures of up to 120°C. It is widely used in the manufacture of parts subject to friction.

Most common uses:

• Gears and bearings
• Structural parts in machinery
• Electrical and electronic components

UHMW polyethylene

Its greatest advantage is its resistance to impact and abrasion. It also has a low coefficient of friction, making it ideal for applications with constant movement.

Most common applications:

• Industrial guides and conveyors
• Coatings on surfaces subject to wear
• Parts subjected to continuous impacts

Acetal (POM)

Known for its low friction and dimensional stability, acetal is used in precision parts where a tight fit is essential. It also resists moisture and various industrial chemicals.

Main applications:

• Heavy-duty rollers and gears
• Valves and hydraulic components
• Mechanical parts in industrial machinery

PTFE (Teflon)

This material is characterized by its chemical and thermal resistance, as well as its non-stick surface. It is ideal for applications where corrosive substances are handled.

Most frequent uses:

• Coatings on industrial machinery
• Gaskets and seals in the chemical industry
• Electrical insulators

In conclusion, the selection of the appropriate engineering plastic depends on factors such as mechanical strength, working temperature, and exposure to chemicals. If you need specialized advice, visit suimtec.com.
