What are the Best Thermoplastics for Heat-Resistant Parts?

A car engine with numerous heat-resistant plastic parts.

When considering options for heat-resistant parts, the first material that usually comes to mind is metal. Alloys tend to have high heat resistance, but the versatility of metals is limited. That’s why an increasing number of engineers are turning to heat-resistant plastics to fill roles in complex, high-performance applications. Heat-resistant thermoplastics also tend to have other beneficial characteristics that lend themselves to an extended lifespan beyond that of metal. Let’s take a look at some of the best thermoplastics for heat-resistant parts and their unique attributes.

Molding clear parts – such as water bottles or food-grade storage items – requires more focused attention to detail and stricter processing controls compared to non-transparent injection molding. Each transparent polymer has varying properties that can influence a company’s decision, including differing levels of strength needs, temperature requirements, and chemical resistance. Even environmental factors such as UV radiation can cause degradation in outdoor equipment utilizing clear plastics. That’s why it’s important to familiarize yourself with the best transparent plastic for your needs.
