torque hinges such as hinge 10 of fig1 one variable that is measured is the resistance to compression set which is defined as the ability to maintain its original torque over time therefore a high quality torque hinge will maintain a high percentage of its original torque throughout its lifetime hinge 20 was tested by performing 30 000 actuations and measuring the torque at varying intervals results showed that after 30 000 actuations considered a product lifetime hinge 20 maintained 92 of its original torque while prior art hinge 10 of fig1 had lost torque consistency the maximum torque being less than 50 of its original torque after only 10 000 actuations coating 22 of hinge 20 may be preferably composed of microcellular urethane mcu foam mcu foam provides high endurance properties as shown in the above testing thereby exuding excellent wear characteristics mcu also provides dimensional stability as shown in the endur u00ae c microcellular urethane products data sheet printed in 1987 by rogers corporation which is hereby incorporated by reference mcu also exhibits good chemical heat and ozone resistance while concurrently being lower cost than conventional torque hinge 10 specifically the current cost for a prior art spring type interference fit torque hinge is approximately 4 50 using two hinges per product the total cost for the hinges is 9 00 per product the new hinge 20 of fig2 costs approximately 2 00 therefore the total cost for the hinges per product is only 4 00 which represents a savings of 5 00 per product or a cost savings of 55 other types of foams may be used in replacement of mcu foam furthermore coating 22 does not have to be a foam coating 22 may consist of.
