TPE 0 degree material production FAQ

　　The momentum of the adult health products industry is still growing, and the demand for super soft TPE is also increasing. We at PlasticBeauty Technology, as the largest supplier of TPE adult products, bring you several common problems in the production of several ultra-soft TPE, we usually in addition to common hardnesses such as TPE 0 degrees, TPE 3 degrees, TPE 5 degrees, TPE 10 degrees, TPE 15 degrees, the user demand for ultra-soft TPE with hardness below 0 degrees (refers to Shore hardness A) is also on the rise.

What can be done with TPE 70 degrees?

　　Introduction of TPE 70 degree 　　Usually we say the degree refers to the hardness of TPE, and this degree refers to ShoreA, 70 represents the hardness value, our TPE raw materials can be from ShoreA 0A-100A. TPE is thermoplastic elastomer, can also be said to be SEBS rubber as the base material modified thermoplastic elastomer materials. We have been dedicated to the research and development and production of TPE since 200 years, and we are more professional in thermoplastic elastomer TPE granules.

TPE｜TPR spray paint peeling｜Analysis and solution of non-stick glue

　　TPE | TPR is used in the process of shoe soles, toys, electronic products, etc. Depending on the function and appearance requirements, it is necessary to brush, paint or spray the surface of TPR | TPE products. However, in some cases, users may encounter problems such as poor paint adhesion and paint flaking on TPE | TPR products. The root cause is the poor compatibility of the glue coating system with TPE | TPR, which cannot form a certain corrosion on the surface of the product, resulting in the glue penetrating into the surface layer of the product and lacking bonding strength. So, how to solve the problem of TPE | TPR products glue is not strong, spray paint ink off? The authors give some ideas, and hope to give the reader some inspiration:. 　　The first step is to determine the TPE | TPR material 　　According to the relevant requirements of the product, select the appropriate composite system TPE, TPR material. For example, based on abrasion resistance and glue considerations, shoe material TPR usually use SBS system TPR material. Based on softness and elongation considerations of some super soft software toys usually consider SEBS system of super soft TPE. 　　Step 2 Paint glue matching TPE|TPR 　　After matching TPE | TPR material is finished, you need to choose the corresponding paint. Select the coating according to the characteristics of TPE and TPR. About the choice of coating, here is a small suggestion for TPE to let TPE<TPR raw material suppliers to provide some test pieces, and then to the glue paint manufacturers to do testing. Until the debugging of the appropriate paint glue. 　　The main elastomer sticky glue paint difficulty 　　Paint and glue solvents to the TENA water, toluene, water-based acrylate type mainly. With this type of solvent debugging out of the glue, for the main elastomer surface processing, the difficulty is roughly ordered as follows. 　　SBS system low hardness|SBS system (medium to high hardness) "TPU|TPEE" SEBS system low hardness "SEBS system high hardness|TPV|TPO. 　　Some TPE products are more solvent resistant, need to do surface treatment with treatment water first, then brush glue or spray paint. 　　TPE products encounter stretching paint ink off 　　Main reasons. 　　1 The solvent of the paint fails to penetrate into the shallow surface layer of TPE products, and when the products are stretched, the paint which is not firmly bonded will naturally fall off. 　　2 The resin component of the paint is less, although the bottom layer is firmly bonded, but when it encounters stretching, the tensile property is not enough, resulting in the surface cracking. 　　Corresponding solution countermeasures. 　　1. first do surface treatment, then spray paint, or change the polarity and TPE substrate closer to the solvent to adapt the paint. 　　2. Increase the content of tackifying resin in the paint composition. 　　Summary: Although a slap on the wrist, but TPE|TPR material is the basis, generally first choose a good TPE, TPR material, and then choose the corresponding paint glue to match the TPE|TPR material. Choose what kind of glue and paint, you should consult with the paint manufacturer, if necessary, to provide TPE|TPR samples.

TPE｜TPR material internal stress manifestation and elimination measures during molding

　　Internal stress (interior stress), referring to the explanation of Baidu Encyclopedia (for more detailed explanation of the concept of internal stress, please refer to this entry), refers to the stress that remains inside the object when the external load is removed. It is generated by uneven volume changes in the internal macroscopic or microscopic organization of the material. Internal stress is a common mechanical phenomenon in polymer materials during molding and processing.

TPE/TPR sales quotation and purchasing skills sharing

　　It is the nature of customers to ask for prices. When a customer goes to a clothing store and sees the clothes he or she wants, it is only natural to ask for a price. Even in the TPE and TPR industry, it is common for customers to ask for price, but as in any other industry, whether or not the offer is properly grasped will directly affect the success or failure of sales activities.
