TPR characteristics: 1. TPR is a kind of thermoplastic rubber material, which is usually modified by SBS. The color is transparent or white particles; The shape is particles, usually spherical particles, ellipsoidal particles and thin round strips, with bright surface and good reflection performance. 2. TPR material has the characteristics of rubber and has good elasticity, resilience, shrinkage, wear resistance and weather resistance. But compared with rubber, the processing method is simpler. It can be processed and produced by ordinary injection molding machine, and can be used for toughening modification of plastics. It can also be used for secondary injection molding of PS, PA, PP, ABS and other materials. 3. TPR is superior to rubber in softness and comfort. Rubber has excellent resilience, good wear resistance, skid resistance and shock absorption, but the tensile strength, fatigue resistance and mechanical properties of TPR materials are inferior to those of vulcanized rubber. 4. The hardness of SBR modified TPR can be adjusted between 5 and 100 Shore hardness, and the hardness of SEBS modified material can be adjusted to lower hardness. The shrinkage of TPR raw materials is 1.5 ~ 3%. 5. TPR, as an environmentally friendly polymer material, does not contain phthalate esters. According to RoHS, reach, EN71-3 and ASTMF963. 6. TPR also has some shortcomings. The chemical resistance, weather resistance and hydrolysis resistance of TPR are inferior to SEBS modified TPE to some extent, which is why TPE is used instead of TPR in many high-end products in the market. But in other words, TPR also has its advantages, such as TPR, glue, ink, etc., which have good adhesion performance and good oil mist screen printing process. It is widely used in shoes and toys. 7. TPR is based on SBS, and its chemical properties are: weather resistance, aging resistance and temperature resistance of 70 ~ 75℃. If materials with good aging resistance and temperature resistance are needed, the modified materials of SEBS substrate can be selected. TPR molding features: 1. TPR raw materials can be used to process various rubber and plastic products by molding methods such as injection molding, extrusion, blow molding, pouring and coating. 2. For some products that need to be dried before processing, it is recommended to dry at 60~80℃ for 2 hours; The recommended injection temperature for SBS substrate is 130~190℃, and that for SEBS substrate is 120~250℃. The hardness and physical properties of TPR raw materials have a large adjustment space, so the processing temperature of TPR materials shows a wide range of changes. 3. TPR can be made by secondary injection molding, two-color injection molding, composite injection molding of PP, ABS, PC/ABS, PA, PS and PE or composite molding with metal materials. TPR materials with different formulations and physical properties should be selected according to customer requirements for different hard rubber materials molded by secondary injection molding. The application fields of TPR are as follows: It is TPR with the above characteristics that has successfully replaced silicone, rubber, PVC and other materials in many fields. Widely used in: daily necessities, baby products, stationery products, interest products, medical treatment, automobiles, electronic communication, industrial appliance handles, various handles, kitchen supplies, food contact level, luggage cart casters, diving equipment, sports equipment (tension belts, tension tubes, yoga mats, bathroom products, etc. Dongguan Dechuang Chemical Co., Ltd. is a professional R&D manufacturer of TPE/TPR rubber and plastic raw materials. TPR materials produced by Dechuang Company are mature and applied in the market. TPR raw materials with different properties are customized according to different needs of customers.
