Benefits of technology

The technology described by this inventor allows for better control over its properties when used with certain materials like rubber or plastics during manufacturing processes such as bonding them together without causing damage due to excessively large forces applied on it. This results in improved durability and stability even after being exposed to harsh environments where they may have been subjected repeatedly to thermal stress cycles.

Problems solved by technology

The technical problem addressed in this patented text relates to improving the efficiency at removing excess heat from electronic devices while maintaining their thinness or lighter weight without losing functionality due to insufficient coolant flow caused by conventional methods such as glue stickers that use static electricity.
