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.

　　First of all, in our daily lives, we have contact with the TPE material made of many types of products, Plastic Bo Rubber & Plastic Technology introduces several common TPE materials to distinguish methods:

　　1, odor: usually SBS-based TPR than SEBS-based TPE flavor, the general good TPE can be done basically odorless;.

　　2, gloss: usually SBS-based TPR than SEBS-based TPE more glossy, of course, SEBS can also have a glossy, SBS-based TPR can also be done matte, but also matte, SEBS-based TPE feel more delicate, SBS-based TPR feel a little rough. In addition, SEBS base material domestic molecular weight distribution is wider, the same molecular weight grade of the base material, made of TPE, imported more matte and delicate.

　　3, processing temperature: usually SBS-based TPR in 150 ° C or so can be thermoplastic processing, and SEBS-based TPE needs to be thermoplastic processing in 180 ° C or so, of course, also depends on their molecular weight, if the molecular weight is high, the processing temperature is also higher.

　　4, sticky: because the SBS base material is not as good as SEBS oil absorption ability, usually SBS base material TPR is more likely to feel sticky than SEBS base material TPE. Of course, some low molecular weight SEBS or its sub-brand is also easy to cause sticky situation.

　　5, TPE is a general term for all thermoplastic elastomers, which mainly includes TPV, TPR, TPO, TPU, TPEE, TPAE, etc., so it can also be a simpler way to distinguish. In TPE materials, because SEBS is filled with oil more, SBS is filled with oil less, so to distinguish between SEBS and SBS who has a high content, an easy way to use the combustion, TPE due to the relatively high hydrogen content, less burning smoke, irritating odor light, gasoline smell. And SBS add more, there will be a lot of black smoke, irritating odor strong;.

　　TPE material if the same system under the premise, naturally, the better the elasticity, weather resistance, transparency, processing stability, and you are on the above several methods, or not quite understand, Plastic Bo told you the last method, in fact, is not very professional knowledge can distinguish.
