For people who are new to the TPE material industry, there is a lot of ignorance about TPE materials, and some people even think according to their own thinking, that is, they think it is so. In life there are many people tend to impose a causal relationship between two unrelated things, because of this, so it is. In the face of such a situation, we can only learn more to learn professional knowledge, so that they become a professional, the following shares to everyone TPE material common several types of misconceptions.

　　1. TPE is only a class of materials? Price is more fixed?

　　Some users, a call over to ask, your home TPE how much a ton. It seems that TPE is so a material, and the performance is relatively fixed, the price is also relatively fixed. But in fact, TPE contains many types, such as TPU, TPV, TPEE, and TPR (TPE) based on SEBS and SBS substrates. There are many types of TPE, not a material, so naturally the price cannot be quoted freely.

　　In addition, by the way, most of the TPE usually refers to the SEBS-based modified elastomer TPE, which also has different hardness and physical properties, and the price should be evaluated according to customer requirements.

　　2. There are liquid TPE?

　　Some users do very soft products, or ready to do a new product, for the convenience of processing considerations, hope to have a liquid class of TPE, direct glue filling curing molding. But in fact, liquid TPE is not available. TPE is a solid elastic particle at room temperature, usually requires high temperature heating and melting to have flow characteristics.

　　3. TPE can perfectly replace PVC?

　　TPE is more environmentally friendly, non-toxic and safe than PVC, which does not contain halogen, o-phenylene plasticizer and heavy metals. tpe has excellent low temperature resistance than PVC. tpe is more comfortable and smooth to the touch than PVC, with better abrasion resistance and non-slip properties. These characteristics seem to give people reason to believe that TPE can perfectly replace PVC.

　　But in fact, some application industries, if there is no higher environmental testing requirements, non-potable water pipes, non-use bags, etc., can actually use PVC, because PVC is cheaper than TPE. The actual situation is that, for price reasons, TPE in some industries to replace PVC, there is still a process. In addition, from the processing aspect, PVC's unique drip (micro injection) process, glue-lined process, is still unimaginable TPE.

　　4. TPE secondary injection molding (overmolding) bonding is not good, it must be the problem of material?

　　Cover glue is an important application of TPE, plastic Bo often encounter users consulting TPE cover glue sticky problem. Some users will be the first time to suspect that the material is the problem. Of course, it is possible that the material is the problem of bad adhesive, but secondly, it may also be due to the insufficient temperature of the customer's injection molding. Different TPE materials and different hard plastics for overmolding, mold and product structure, etc. will be considered as factors for molding temperature setting.

　　TPE material common several types of misconceptions to share here, the problem is still to be found in our work and life. Problems are progress, and the biggest problem is no problem.
