TPE｜Can TPR be wrapped with adhesive metal?

　　Can TPE|TPR be used to cover metal? 　　Aluminum, stainless steel and other metals cannot be directly covered with TPE. This is different from TPE|TPR overmolded plastic. However, with the increasing application of TPE, more and more products need to use TPE to cover metal. How to wrap the glue, there are two ways.

TPE｜TPR injection molding product color difference control should pay attention to the six aspects

　　Color difference is a common defect in TPE injection molding, and it is not uncommon to see batches of injection molded products scrapped due to the color difference of matching parts. Not considering the subjective factor of different people's visual perception of color differences, there are many objective factors affecting the color difference of TPE|TPR products, including TPE raw materials, color masterbatch (or color powder), mixing of color masterbatch with TPE raw materials, injection molding process, injection molding machine, mold, etc.. Because of the wide range of factors involved, the color difference control is one of the more difficult techniques to master in TPE color matching injection molding. In the actual production process, we generally control the color difference of TPE products from the following six aspects.

TPE/TPR injection molding temperature issues - factors affecting

　　TPR, usually refers to styrenic thermoplastic elastomer SBS, SEBS and other resins and additives mixed into a dry molecular alloy of elastomers (TPES). As the most commonly used TPE refers to styrene elastomer alloy TPES, and the TPE in China generally refers to TPES elastomer, therefore, the TPE/TPR in this paper is based on SEBS, SBS base material modified materials.

TPE/TPR painting and spraying common problems analysis and solutions

　　1. Basic structure of TPE/TPR paints. 　　The main components of TPE/TPR paints in the local market are: 1) Resin 2) Solvent 3) Toner 4) Additive. Among them, resin is the main component of the paint, its function is to make the pigment bonded to the surface of the plastic parts. Generally speaking, the resin of the sprayed plastic parts and the oil should be roughly the same in chemical class, so as to ensure that the plastic parts and the paint can be well sprayed without causing the paint or ink to fall off. This is actually a matching problem between the rubber and the paint.
