Design Properties for Engineers: Price Performance Ratio of High Performance Polymers

 In this blog post, we compare the performance and prices of high performance polymers (HPP) in a quantitative way. 

The costs per kilogram of HPPs are higher when compared to commodity and engineering plastics. However, commodities lose their dimensional stability already below 100°C use temperature. 

The performance advantage, i.e. long-term retention of mechanical properties at elevated temperatures or when exposed to chemicals justifies the higher price level of high performance polymers in comparison to commodity and engineering plastics in such demanding applications. 

Furthermore, price comparison should be done on a density and part volume basis, combined with performance requirements as explained before. 

I hope you found this post useful!
