Hello, everyone. I'm Zhanghuimin. I speak for TPE/TPR/TTPU / TPEE! The plastic elastomer TPE is a material with high elasticity, high strength, high back elasticity, and the characteristics of injectable molding. It has environmental protection, non-toxic and safe, wide range of hardness, excellent coloring, soft touch, weather resistance, fatigue resistance and temperature resistance, superior processing performance, no need to vulcanize, can be recycled to reduce costs, can be secondary injection molding, It can be bonded with PP, PE, PC, PS, ABS and other matrix materials and can also be formed separately. One: The concept of TPE packaging: TPE packaging, as the name implies, is to glue TPE soft adhesive material to other materials. The general processing methods used are two-color injection molding machines for one molding, or general injection molding machines for the use of plastic mold, divided into two injection molding. TPE plastic molding products, generally some handles, handlebars products. Because of the special comfort touch of TPE soft adhesive material, the introduction of TPE material has improved the grip and touch feel of the product. II: TPE material concept: TPE material is a general term for thermoplastic elastomer, English full name Thermopolistic Elastomer. It is a kind of functional material with both rubber elasticity and plastic stiffness, which can be directly injected into extrusion molding. The TPE material that is generally coated refers to the TPE-S, a polystyrene thermoplastic elastomer, which is a thermoplastic engineering plastic obtained by composite modification of a substrate with a sebs or SBS elastomer. TPE-S elastomers are also commonly referred to as TPE or TPR in the elastomer industry. Third: TPE plastic PCmaterial characteristics: TPE thermoplastic elastomer is SEBS rubber modified material, rubber elastic, can be easily injection molding or extrusion molding. The hardness range of the adhesive can be adjusted at Shore A0 ~ 100 degrees. The TPE adhesive used for encapsulating PCs has a common hardness range of 30 to 80 degrees, and its appearance is of the same color or translucent particles. The adhesive material has good wear resistance, good adhesion with PC wrap, and the product made is comfortable and smooth. TPE coated PC processing method: TPE coated PC, generally using the usual molding method, that is, using two sets of molds, one set of injection plastic PC products, another set of molds(called plastic molds) For the TPE coated plastic injection plastic to the PC product surface. This type of molding method is called secondary injection molding, coated molding or embedded injection molding. There are also more advanced two-color injection molding machines. The results are the same. TPE and PC are well bonded together by injection molding. The injection plastic temperature of the adhesive is different depending on the hard plastic material of the adhesive. Because of the temperature, both hard gum and TPE soft gum must be softened so that the two materials can achieve certain compatibility at the contact surface. In order to achieve the true adhesive effect, the injection molding temperature of TPE adhesive PP material is usually about 170 to 190 degrees Celsius; The plastic ABS material is about 220 to 220 degrees Celsius; The temperature of the coated PC material is slightly higher than the injection temperature of the coated ABS. V: The main advantages of TPE application to coated elastic adhesive: TPE elastomer soft adhesive applied to secondary injection molding, coated elastic adhesive. Because TPE materials have good sliding properties and good elastic touch, it can enhance the touch feel of the product and enhance the grip. TPE elastomer soft rubber can be adjusted to the appropriate hardness(hardness range Shore 25-90A) according to the physical properties of the product, and suitable physical properties(such as abrasion resistance, scrapability, adhesion, melting index, etc.). A variety of possible materials applications are available for different products. TPE adopts coated adhesive processing, commonly used products such as handles, grips, electronic materials, etc.. The material gives the product a comfortable touch, improves the grip, enhances the beauty of the product and adds value to the product. Most of the products are exported to the United States, JPN and the European Union and other developed countries and regions. Because TPE elastomer soft gum is a green and environmentally friendly raw material, the material does not contain phthalates, does not contain halogens, and does not contain 38 SVHC highly concerned substances specified in REACH. In line with the ROHS, REACH, NP, EN71, PAHS environmental inspection standards, it can fully meet the Environmental Protection requirements of the United States, JPN, EU and other developed countries and regions.
