AI Technical Summary

Benefits of technology

The technical benefit of this patented technology relates to an improved method used on plasties made from polyethylene terephthalate (PET) resin by adding certain chemical agents or substances during manufacturing process steps like extrusion molding. This results in coatings which are more resistant against damage caused by external factors such as rubbing force while also having good appearance properties.

Problems solved by technology

The technical problem addressed in this patented text relates to how to improve the durability or resistance against wear caused during prolonged exposure to high temperatures without causing any damaging effects over longer periods of usage.
