TPE products may crack for various reasons, with the most common being weather-related and material strength. When the weather is cold, the molecular structure of TPE material changes, resulting in reduced tensile strength and eventually leading to cracking.

There are many types of equipment for TPE molding, including pull rod cold cutting granulation, water ring cutting, underwater cutting, etc. Each type of equipment has different production capabilities and material adaptability, so they should be selected according to specific circumstances.

　　Thermoplastic Elastomer, the English name is Thermoplastic Elastomer, so it is usually abbreviated as TPE, also known as Thermoplastic Rubber, the English name is Thermoplastic Rubber, usually abbreviated as TPR, both of them are short for Thermoplastic Elastomer.

　　With the development of society, the same production of TPE material manufacturers more and more, the production of TPE (Thermoplastic Elastomer) material quality is also different from each other, and there is a difference between the system of TPE materials, TPE materials, good and bad identification methods are also held by the views.

　　Overmolding in the field of TPE thermoplastic elastomers is a special type of overmolding. And what is overmolding? Simply put, overmolding can be plastic over plastic, or soft rubber over plastic, or soft rubber over soft rubber.

　　First, the concept of TPE overmolded PC 　　TPE overmolded PC, which is a unique term in the thermoplastic elastomer TPE industry, means that the thermoplastic elastomer TPE is bonded and overmolded to the surface of PC (polycarbonate) plastic parts by injection molding to give the product some functional requirements.

　　A few days ago with colleagues to go out to try material, the customer is to do electronic products, with our TPE material to wrap the rubber, because they have identified the main material is ABS, just use our

　　Analysis of the causes of color migration of TPE plug material. 　　Color migration 　　Small molecule material migration 　　TPE, TPR products in the modification process, sometimes add some small molecular weight additives, but this kind of additives and the base material compatibility is poor, the general additive amount of 2 ~ 3 ‰. If the amount added is too much, it will lead to small molecule substances will be extended with time, and migration occurs.

　　TPU products have very good processing performance 　 　　TPU Chinese name for thermoplastic polyurethane elastomer, TPU because of its plasticity and versatility, is widely used in all walks of life, and its advantages and characteristics are not comparable to other materials.
