AI Technical Summary

Benefits of technology

This patented technology helps prevent damage caused by repeated use on vehicles' wheels due to reduced friction between them during vehicle operation. It uses small molecules called polyfunctionality agents made up of specific sequences of aminic acid or other organisms attached to certain parts of these polymers. These tiny particles help create strong bonds within the rubbers themselves without affecting their elastic properties like flexibility at high strains. By adding this agent into the rubbing process itself, it improves its durability over time.

Problems solved by technology

This patented technical problem addressed in this patents relates to improving the performance of tire materials used for vehicles due to their ability to decrease its roll-resistance without compromising other important properties such as durability or safety issues associated with traditional methods like adding antihistamines (which are commonly known antioxidants) during manufacturing processes that involve high temperatures).
