Benefits of technology

This patented technology describes an improved method for preparing highly strong composites that are resistant against frictional damage caused during use or operation on various machines like engines. These compositions consist mainly of organopolymer matrices made up mostly of carbon atoms called polytetrafluorylene (PTFE), epoxy groups, hydroxystrosion resistance polymers, etc., along with other components like lubricants and fillings. By combining these different elements together they create stronger structures without adding extra weight compared to existing methods. Overall this new composition provides better performance over traditional ways than current products due to its unique combination of strength factors and good surface characteristics.

Problems solved by technology

This patented technology describes how adding certain substances like phenolic antioxynitrile (PZN) into an organopolymerizable monomer mixture helps create strong composites with improved performance over traditional methods. Additionally, this approach allows us to combine different types of polymers together by adjusting their react mechanisms based on factors like environmental conditions and use requirements.
