AI Technical Summary

Benefits of technology

The inventive polymers have several technical features: they are strong with shock absorption properties for use inside car parts like doors or pillars. They also resist damage from external factors like bending force caused when an object hits them during normal usage conditions without being damaged themselves. This makes these materials ideal for applications where strength, durability, and protection against environmental hazards should meet stringent requirements.

Problems solved by technology

Technological Problem addressed by this patented technology describes how modifying polypropthylene (PP) makes them easier to use than regular ones while still having some beneficial qualities like flexibility, heat/oxygen resistence, etc., which may cause issues if they were applied externally over an extended period of time without being properly controlled.
