TPE elastomer soft rubber can be adjusted to appropriate hardness (hardness range Shore 25-90A) according to the physical property requirements of products. In order to produce the matte appearance of thermosetting rubber, a rough mold appearance is required. Generally speaking, the rough appearance of die cavity after EDM will produce excellent workpiece appearance and make demolding comparison simple. Grinding methods such as steam explosion, sand blasting or shot blasting, and chemical etching can also be used to produce appearance with different luster and appearance. Transparent tpe materials have different product properties in different aspects. Thermoplastic elastomer is also called tpe material. Transparent tpe not only has the processing properties of thermoplastic, but also has the physical properties of vulcanized rubber, which is the combination of advantages of plastic and rubber. Transparent tpe is widely used in people's daily life and production. Transparent TPE manufacturer And suitable physical properties (such as abrasion resistance, scratch resistance, adhesion, melt index, etc.). Various approximate material application plans are provided for different products. The key point of the overmolding (secondary injection molding) of TPE is to make TPE and coated substrates PP,ABS,PC,PA, etc. To make TPE adhere well to the coated substrate, Styrene transparent tpe, which is widely used in footwear industry, has mostly replaced rubber; At the same time, its application in industrial rubber products such as adhesive tape and rubber sheet is expanding. As any impurities in TPE materials may affect the transparency of products, attention must be paid to sealing during storage, transportation and feeding to ensure the cleanliness of TPE raw materials. Especially, TPE raw materials contain moisture, which will cause deterioration of raw materials after heating, so it must be dried. During injection molding, a drying hopper must be used for feeding. Transparent TPE manufacturer According to the principle of chemical similarity compatibility, the key point is that TPE and coated substrate should have similar polarity, so that TPE and coated substrate can fuse at molecular chain level. TPE is applied to encapsulation and injection bonding, and TPE soft glue is used as the outer coating of soft glue. The application of TPE high transparency material has different product performance in different aspects. Thermoplastic elastomer is also called TPE material. Transparent TPE not only has the processing properties of thermoplastic, but also has the physical properties of vulcanized rubber, which is the combination of advantages of plastic and rubber. Transparent TPE is widely used in people's daily life and production. Thickness of TPE and TPR coating. In most overmolding applications, a wall thickness of 1.5-3.0mm will ensure good adhesion. If the TPE glue position is too thin, injection molding is difficult, the adhesion strength is low, and the hand feeling is poor. If TPE glue position is too thick, on the one hand, the cost is high, on the other hand, it is easy to shrink and bubble. Transparent TPE manufacturer Common hard materials are mainly plastics, but also metals and woven fabrics. The injection bonding of TPE and woven fabric is mainly used in luggage products, which is the same as metal encapsulation. True encapsulation is more common in secondary injection molding and two-color injection molding, that is, the main material of TPE encapsulation and injection adhesion is plastic.
