TPE is renowned for its excellent elasticity and tensile strength. However, some users often encounter issues with poor tensile strength and ease of breakage when processing TPE materials. Common reasons for poor tensile strength in TPE products include:

1. The addition of more fillers to the TPE material has resulted in a decrease in its tensile properties and flexibility.

2. Excessive amount of recycled scrap added during the molding process of TPE materials.

3. The TPE material base has a low molecular weight, which does not meet the high tensile requirements.

4. When TPE materials are molded at excessively high temperatures, the material undergoes degradation, resulting in a decrease in physical properties, material brittleness, and reduced toughness.

5. The TPE material did not reach the proper molding temperature, resulting in insufficient plasticization and poor tensile strength.

Solution:

Reduce the proportion of filling material added.

2. Water nozzle edge materials have poor tensile strength. Over-addition tends to reduce the tensile strength of TPE materials. It is recommended that the addition ratio of water nozzle edge materials be below 25%.

3. Switch to high molecular weight substrates.

4. Familiarize yourself with the appropriate molding temperature for the TPE material being processed. If in doubt, it is recommended to consult the material supplier.

5. Determine if the molding temperature is too low: First, inspect the surface luster of the product; if the surface luster is low or even appears matte, the molding temperature of the material needs to be increased. Second, examine the sprue; if the sprue surface lacks luster, the plasticizing temperature is too low.
