Expert Commentary
Measures the Adhesion of Tire Cords to Rubber (H-Test). The tire cord is vulcanized into two separate rubber blocks, forming an H shape. The test pulls the blocks apart to measure the Pull-Out force. The technical challenge is the Temperature Control. Since tires operate at high temperatures, MTO provides integrated environmental chambers to test at 120°C. This is a critical safety specification for the tire industry, ensuring the mechanical bond between the reinforcement and the matrix survives the life of the tire.
