Analysis of the causes of discoloration of TPE/TPR products

　　Analysis of the causes of discoloration of TPE/TPR products 　　Influencing factor one. 　　The influence of tpe raw materials on discoloration 　　1, the material is contaminated. 　　2, high content of moisture and volatiles. 　　3, colorants, additives decomposition. 　　Influencing factor two. 　　The setting of the injection molding process in tpe plastic parts also affects the product discoloration 　　1, screw speed is too high, pre-molding back pressure is too large. 　　2, the barrel, nozzle temperature is too high. 　　3, the injection pressure is too high, too long, the injection speed is too fast to make the product discoloration 　　Analysis of the plastic ber. 　　First of all, TPE raw materials on the impact of discoloration, the first and third are easy to understand (colorants, additives degradation and decomposition, their own discoloration, will naturally lead to discoloration of TPE products), and the second to be experienced professionals to explain the interpretation of doubt. 　　As for the injection molding process setting, the three influencing factors may lead to excessive friction and shear force or high temperature of the material, resulting in the possibility of degradation and discoloration, and if colorants are added to the material, the decomposition of colorants may occur and lead to discoloration of the final TPE products.

TPE/TPR particle lumping and sticking main reason analysis.

　　TPE/TPR particle lumping and sticking main reason analysis. 　　1. Granulation process problems. The granulation process, material cooling is not sufficient, at a higher temperature on the packaging for finished products, heat gathered in the bag, and the higher the ambient temperature, the material is more likely to spit oil lumps.

TPE/TPR transparent natural color material yellowing resistance anti-UV effect how to identify

　　When it comes to yellowing resistance and UV resistance, first we must know that TPE is composed of those materials, as we all know, TPE material in the production process is a physical reaction process, rather than a chemical reaction process, he is made of polymer materials SEBS or SBS oil-filled blend, in the production process if you want to achieve the desired effect on the addition of the right amount of additives, in the TPE production process for SEBS / SBS such a base material requirements are quite high. SBS such a base material requirements are quite high.

TPE / TPR get samples will be how to test

　　We must analyze the various properties of the products after we get the TPE products back, so how do we analyze and measure them? The analysis and testing equipment is divided into two pieces, one is the analysis instrument and one is the testing instrument.

TPE/TPR rubber pellets caking cause analysis and solution

　　A, TPE / TPR transparent material lumping cause analysis 　　1、High proportion of oil filling; sometimes for the production of super soft hardness products, need enough proportion of oil in the SEBS/SBS blending system, but the oil itself is viscous, the greater the proportion of oil, the greater the possibility of precipitation (oil spitting), which leads to transparent particles lumping.

What are the molding methods of TPE/TPR

　　TPE/TPR can be processed with general rubber processing equipment or plastic processing equipment. After proper control of processing temperature and processing conditions, the finished product will be of uniform and stable quality. The commonly used processing methods are Extrusion, Injection, Blow molding and Pouring.

What to pay attention to in TPE/TPR molding process

　　I. If the surface of the product is strict, it must be dried before injection. Generally, it is 70~80℃/2h for hopper drying or 80~100℃/1h for pallet drying. for pallet drying, it should be noted that the thickness of material layer is generally not more than 50mm. It is recommended to use pallet drying. If the surface of the injection molding strip has blistering, or cut open the strip and find that there are hollows inside, or find that the surface of the product and scattered silver wire, it can be determined that the TPE/TPR raw materials contain too much moisture.
