When there is a great difference between the polarity and the surface energy between the plastic and the rubber, if the appropriate compatibilizer is added, and then the dynamic vulcanization can be carried out, the blends with good properties can be obtained. [2] specific performance profile 1, good elasticity and compression deformation resistance, environmental resistance, aging resistance is equivalent to the three Yuan Yibing rubber, while its oil resistance and solvent resistance and general purpose chloroprene rubber. 2, the application of a wide range of temperature (- 60 - 150 degrees), the application of a wide range of soft hardness (25A - 54D), the advantages of easy to greatly enhance the degree of freedom of product design. 3, excellent processing performance: can be used for injection, extrusion and other thermoplastic processing methods, high efficiency, simple, no need to add equipment, high mobility, low shrinkage. The name of TPV thermoplastic vulcanizates and if some detail, it should be thermoplastic vulcanizate (English Thermoplastic DynamicVulcanizate), and the "dynamic" 2 words is more detailed description of the process of the production of dynamic vulcanization thermoplastic vulcanizate, this process in rubber and thermoplastic plastic melt blending process of vulcanized rubber, vulcanized rubber in the course of the at the same time with thermoplastic mixture is therefore the vulcanized rubber is used as the dispersed phase dispersed in the continuous phase, thermoplastic composition in short, many plastic and rubber can form TPV, but only the individual blends after dynamic vulcanization has practical value, commercial PP/PE/EPDM, PP/NBR, PP/ACM, PS/SEBS. In the chemical industry press "thermoplastic elastomer" in a Book of 11 kinds of rubber and 9 plastics prepared 99 Kinds of rubber / plastic blends are reviewed, the study found that in order to get better performance of the rubber / Zui thermoplastic vulcanized blends, must meet the following conditions. TPV 2054, TPV 2060, TPV 2065, TPV 2087, TPV 2160, TPV 2073, TPV 2075 Defect analysis and solution of TPE injection molding: The finished mold after Ray speed too fast, the cavity air cannot instantly reduce discharge of fire, the air cavity smoothly discharged from raw materials containing moisture drying high molding temperature, molding temperature decreased by high temperature decomposition of the threshing barrel with air into the tube after reducing the material temperature, high pressure Finished mold flashing after the pressure is too large, the parting force is greater than the clamping force, forced open mold to reduce pressure, fly a mold clamping force, increasing injection pressure and holding pressure is too large at lower pressure and pressure injection through fast, high temperature material lowers the firing rate and feeding temperature of venting plug hole cleaning die Products filling insufficient injection pressure, lack of speed is too slow or die or increase the injection pressure, increase rate of fire and cleaning die nozzle runner molding temperature is too low, too small to improve the molding temperature, modify the air cavity channel can not be completely discharged add or increase the exhaust hole injection time is too short, insufficient amount of shoot extension injection time, injection volume increased Products with line injection pressure, injection speed is too slow, the gate and the channel is too small On the other nozzle of low temperature, long processing cycle, titanium dioxide color masterbatch dispersion is not good too, is also one of the reasons to improve the injection pressure, injection speed, modify the runner molding temperature and mold temperature is too low to improve the molding temperature and mold temperature, increase the back pressure or accelerate the speed of the screw combined parts exhaust poor or no overflow pool (cold well) increase or increase the confluence part vent overflow pool used to reduce the usage of the multi release agent release agent TPU dissolved, after processing to obtain polyurethane adhesives. In the TPU adhesive use, mainly in the four main areas of Guangdong, Fujian, Zhejiang, Shanghai. 4 because the TPU has a soft hose hose, tensile strength, impact strength, good resistance to high temperature, so in the China TPU hose is widely used as aircraft, tanks, automobile, motorcycle, machine tools and other mechanical equipment such as gas, oil hose. Major TPU hose manufacturers are concentrated in Guangdong, Zhejiang, Jiangsu, Shandong, Hebei and other places. 5 wire TPU provides tear resistance, wear resistance and bending characteristics, high and low temperature resistance is the key to the performance of the cable. Therefore, in the Chinese market, such as the use of advanced cables, such as control cables and power cables TPU, used to protect the design of complex cable coating material, the use is also increasingly widespread. 6 roller polyurethane elastomer with its high mechanical strength, excellent wear resistance, excellent oil resistance, acid and alkali resistance, outstanding resistance to compression and make it in the roller has a lot of applications. Domestic roller has the following several kinds: industrial roller, household roller, sports equipment wheel, medical equipment wheel, toy wheel. 7 plastic modification can be used for PA, ABS plastic, but higher cost. TPU 315F, TPU 518/1, TPU 530/2, TPU 618/1, TPU 616/1, TPU 704, TPU 917/1, TPU 927 PC / / /ABS melting temperature: 230~300C. Mold temperature: 50~100C. Injection pressure: depending on the plastic author Xuan Yang Plastic - Qiu Feng directory? Solvent PC / / PC / / /ABS /ABS concept /ABS "PC picture material, polycarbonate and acrylonitrile butadiene styrene copolymer and the mixture is made of polycarbonate (Polycarbonate) and polyacrylonitrile (ABS) alloy made of thermoplastic plastic, combined with the excellent properties of two kinds of materials, molding and PC / / ABS material mechanical properties, impact strength and temperature resistance, anti ultraviolet (UV) and other properties, can be widely used in automobile interior parts, business machines, communication equipment, household appliances and lighting equipment. The drying conditions of the injection molding process: it is necessary to do the drying treatment before processing
