Benefits of technology

This new type of material made from polyethylene terephthalate (PE) and phosphorus pentoxide resin crosslinked together improves its resistance against static electricity without affects their ability to conduct electrical current effectively. It also prevents fire hazards caused by burning plastic materials containing combustible substances or other harmful gases during fires. Additionally, it provides effective protection for electronic devices used at high temperatures such as computers due to low volatility thereof when exposed to these conditions over time.

Problems solved by technology

The technical problem addressed by this patented technology relates to improving the performance of materials like polycarbonsulfone polymers or copolymerized polystyrene sulfonamide fibers when exposed to extreme temperatures without causing damage from electrostatic charge buildup caused by their weight. This issue becomes more challenging because there may also exist substances called antiquat chemicals which prevent static electrical charges on certain parts of the material being modified. Additionally, traditional methods involving modifying the surface layer of the article containing them tend to lose some part of its original function over time if they were applied repeatedly.
