Application of TPE in the field of mechanical tools

TPE (Thermoplastic Elastomer) applications in the field of mechanical tools are extremely broad, with its presence spanning across handle over-molding, sealing and dust prevention, damping, vibration reduction, and noise reduction. Depending on the specific application requirements, the performance considerations for TPE also vary.

In the application of handle over-molding, the primary considerations are the compatibility and adhesion strength of TPE with the hard plastic substrate. This necessitates a careful selection of raw materials. Based on varying application demands, the hardness of TPE can range from Shore A25 to Shore A85. In the context of sealing and dust prevention, the permanent compression set and temperature resistance of TPE are critical factors to consider, making TPV (Thermoplastic Vulcanizate) a popular choice. The hardness range for TPV is generally between Shore A45 and Shore A75. For damping, vibration reduction, and noise reduction applications, we need to select special raw materials that have higher loss modulus and peak Tangent Delta values at the application temperature. Depending on the specific usage scenarios, the hardness can range from Shore A5 to Shore A95.

In summary, the application of TPE in the field of mechanical tools requires a comprehensive consideration of factors such as material compatibility, adhesion strength, hardness, temperature resistance, and loss modulus to ensure that the product performance meets specific application requirements.
