What are the specific manifestations of performance degradation in TPE thermoplastic elastomers after moisture absorption? Below, the Zhongsu Wang TPE team will address this issue.

TPE materials are not a single substance but a vast family encompassing numerous systems with distinct chemical structures. Among these, softening temperature serves as a key indicator for evaluating TPE's heat resistance and determining its upper application limit. It is not a strictly defined physical constant but rather a temperature range characterizing the transition from a rigid solid state to a soft, viscous flow state. So, what are the differences in softening temperatures among various TPE materials?

Flame-retardant TPE has long been widely used in safety-critical industries such as electronics, automotive, and cables due to its excellent flame retardancy, flexibility, and processability. However, storage conditions directly impact its flame-retardant effectiveness. Improper storage can lead to flame retardant leaching and reduced mechanical properties, threatening the safety of end products.

TPE materials are polymeric substances that combine the properties of rubber and thermoplastic plastics. They exhibit high elasticity like rubber at room temperature and can be plasticized and molded at elevated temperatures.

In the injection molding process of TPE thermoplastic elastomers, drying treatment is a critical step in ensuring product quality. Whether it is injection molding, extrusion, or blow molding, if the moisture content of the material exceeds the specified limit, it can easily lead to surface defects such as bubbles and surface defects, and even cause serious issues like reduced adhesion and performance degradation. Therefore, scientifically and reasonably determining the drying time for TPE thermoplastic elastomers is a prerequisite for ensuring smooth production and product quality. So, how exactly is the drying time for TPE thermoplastic elastomers determined?

TPE materials are increasingly used in various applications due to their advantages of ease of processing, weather resistance, soft texture, and ease of coloring. However, products made from TPE inevitably exhibit signs of aging over time. How can the aging of TPE materials be slowed down?
