Thermal Shrinkage-Force Tester



Reference standard

ASTM D4974-01 standard

Use/Good point

When the thread or cords were expose in the heated air, This apparatus is used for the determination of thermal shrinkage and force. It is just apply to the thread or cords used to produce polymer of nylon and polyester, not damaged by heat.
Insert the specimen into the hot air closed by the heating plate top and bottom. Catch the change of thermal shrinkage and force, print it out. Through the connection of recorder, the result can be drawn by the graph.
