TPR manufacturers: process steps and requirements of injection molding tpr

​ This article mainly talks about the process steps and requirements of injection molding TPR. According to the characteristics and supply of the material, the appearance and process performance of the material should be tested before injection molding TPR molding. The particles provided by TPR usually contain varying degrees of moisture, flux and other volatile low molecular weight substances, especially the moisture content of TPR always exceeds the processing allowable limit. Therefore, it must be dried before processing and the water content must be measured. The dried material must be properly sealed and stored to prevent the material from absorbing moisture in the air and losing its drying effect.

TPR manufacturers: TPR soft rubber in the toy industry application and performance requirements

The application of TPR soft glue in the toy industry has become more and more common, in the application field of traditional soft PVC material toys. TPR soft rubber materials have won the favor and trust of consumers with their better environmental protection, safety and non-toxic characteristics. Each industry has its own corresponding standards. As far as the toy industry is concerned, there are also specific industry standards, and different Of toy products have different requirements for the physical properties and processing properties of TPR soft rubber materials.

TPE manufacturers: talk about TPE, TPR self-adhesive, co-adhesive and its application

According to the adhesion mechanism, the viscosity of thermoplastic elastomers TPE and TPR can be divided into two categories: one is self-adhesive, and the other is co-adhesive. Viscosity is an important property of thermoplastic elastomers TPE and TPR. However, in most cases, conventional TPE and TPR do not have functional viscosity, but need to adjust the mixing system to obtain the required adhesion.

TPE manufacturers: what is the difference between TPE and tpr

Both TPE and TPR are thermoplastic elastomers, so there is no difference in their names. However, there are still differences in some applications. Today I will introduce you to the difference between TPE and TPR? Which is better, TPE or TPR. The SEBS hybrid modified material is called TPE, and the SBS hybrid modified material is called TPR, but the name is not authorized by academics, nor is it recognized in the book. First of all, TPE particles are matte, while TPR particles are shiny.

TPE manufacturers: TPE encapsulation problem solving Daquan

TPE encapsulation is familiar to everyone. As the name suggests, it is to encapsulate low-hardness TPE onto the surface of other materials. Processing methods generally include two-shot injection molding process of ordinary injection molding machine and two-color injection molding process of one-time molding. TPE encapsulation materials are widely used in handles, handles and electronic products. Its comfortable touch and softness improve the grip and use comfort of the product. However, for manufacturers of TPE encapsulated products, TPE encapsulation is actually not easy, and a series of problems often occur. Therefore, let’s learn about common TPE encapsulation problems today, and hope to help everyone.
