TPE encapsulation molding, also known as two-color/multi-color injection molding, is an advanced manufacturing process that involves coating TPE material onto another substrate.

TPE， The full name is thermoplastic elastomer, which is a new type of polymer material developed in the late 1950s. Its emergence completely breaks the boundaries of traditional material classification. From a chemical composition perspective, TPE thermoplastic elastomers are typically formed by blending or block copolymerization of two or more polymers.

TPE material is a type of block copolymer, whose molecular chain is composed of alternating hard and soft segments. Hard segments endow materials with strength and melt processability, while soft segments provide elasticity and flexibility. This unique structure makes TPE neither require complex vulcanization processes like traditional rubber, nor completely lack elasticity like ordinary plastics. In recycling, reprocessing, or specific application scenarios, we sometimes need to dissolve TPE materials for mixing, coating, or other processing. So, how does TPE material dissolve? Let's follow the TPE editor of Shenzhen Zhongsu Wang to take a look!

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.
