AI Technical Summary

Benefits of technology

This patented technology involves making an improved type of plastic that combines both thermal performance (heat resistivity) with durability against environmental factors like rainwater or snowfall. It achieves this through adding specific chemicals called polyamidite compounds made from different starting components together into one mixture. These mixtures help create better physical characteristics for these products while still maintain their desired functions over time.

Problems solved by technology

The technical problem addressed by this patented technology is how to improve upon current materials' ability to protect against humidity or liquid damage from exposures during use at very high temperatures such as those found within electronics/electronic devices like power converters.
