Usually rubber needs and softening oil or plasticizer and match. Vulcanizing agent and a number of auxiliary aids is essential. Furthermore, in order to reduce costs or improve the performance of certain aspects of some of the inorganic filler is added to fill. About TPV thermoplastic vulcanizates (English for Thermoplastic Vulcanizate), also known as polyolefin thermoplastic elastomer alloy, referred to as TPV, TPV's Chinese referred to as thermoplastic rubber (English Thermoplastic Rubber), referred to as TPR, but the name is easy and other types of thermoplastic elastomers (English for Thermoplastic Elastomer) confused together, because usually everyone thermoplastic elastomer is also known as thermoplastic rubber, especially styrene elastomer, at least in China seems to "TPR" has become its proper name, and Mention of TPR, refers to SBS, SEBS elastomer such as styrene-based thermoplastic elastomer material, which styrene elastomer in the civilian as well as large areas of the terminal consumption of consumer goods are inseparable. Name thermoplastic vulcanizates little detail if to say, it should be dynamically vulcanized thermoplastic rubber (English for Thermoplastic Dyamic Vulcanizate), plus a "dynamic" two words are more specifically described process to produce thermoplastic vulcanized rubber --- dynamic vulcanization, which In the kinds of processes that the melt blending of thermoplastic rubber and rubber vulcanization process, to, of course, in the vulcanized rubber but also continue to be mixed with the thermoplastic, therefore vulcanized rubber is distributed as a dispersed phase in the continuous phase thermoplastic, In short, TPV obtained by TPO after dynamic vulcanization. Correspondingly static thermoplastic vulcanizate according to the conventional method refers to a rubber vulcanization well, and then vulcanized by a good rubber milling equipment to be ground into powder, and the final molten thermoplastic blends, this approach is theoretically capable of producing have excellent performance TPV, but so far only at the laboratory stage. Many may be formed between the plastic and rubber components TPV, but only after the individual dynamically vulcanized blends have practical value, there are commercial PP / PE / EPDM, PP / NBR, PP / ACM, PS / SEBS. In the chemical Press "thermoplastic elastomer" a book 99 kinds of rubber / plastic blends of 11 kinds of rubber and nine kinds of plastic prepared commented, the study found that to get the best performance of rubber / dynamically vulcanized thermoplastic total blend, the following conditions must be met: (1) surface of the plastic and rubber of the two polymers can be matched; lower (2) the length of the rubber molecular chain entanglement; (3) the degree of crystallinity greater than 15% plastics. Or when the polarity of the surface of the plastic and rubber can be relatively large difference between the case of adding a suitable compatibilizing agent, and then dynamically vulcanized, excellent performance can be obtained blend. 2 Introduction to a specific performance properties, good flexibility and resistance to deformation, resistance to environmental aging resistance equivalent to EPDM rubber, while its oil and solvent resistance and universal neoprene. 2, wide application temperature range (- 60-150 ℃), wide hardness range of applications (25A-54D), the advantages of easy staining greatly improve the product design freedom. 3, excellent processing performance: Available for injection, extrusion and other processing of thermoplastic processing methods, efficient, simple, without additional equipment, high mobility, low shrinkage. 4, green, recyclable, and reusable six no significant decline in performance, compliance with EU environmental requirements. 5, the proportion of light (0.90-0.97), uniform appearance quality, surface high grade, feel good. Based on the above performance characteristics, TPV in a wide range of applications with traditional rubber material, TPE other elastomers (including TPR \ SBS, SEBS, TPU, etc.) materials such as plastic or PVC materials compared to the overall performance and overall cost possess certain alternative advantages, providing new options for products companies in product innovation, improve product value and improve competitiveness. TPV is Thermoplastic Vulcanizate short, the Chinese name for the dynamically vulcanized EPDM thermoplastic elastomer or thermoplastic dynamically vulcanized EPDM rubber, is highly vulcanized EPDM EPDM particles dispersed in a continuous phase consisting of polypropylene PP high molecular elastomeric material. Physical properties and functions similar to TPV room temperature thermoset rubber, high temperature performance characteristics of thermoplastics can be quickly and conveniently economy molding. EPDM TPV dynamically vulcanized thermoplastic elastomer / rubber by dynamic vulcanization of a rubber material vulcanized EPDM EPDM particles less than 2 microns in size dispersed in a matrix of the polypropylene PP plastic, the good characteristics of rubber and plastic together, get high-performance integrated performance elastomer material. The main performance dynamically vulcanized EPDM TPV thermoplastic elastomer / rubber: TPV easy to weld, reusable, environmentally friendly non-toxic. The main features of dynamically vulcanized EPDM TPV thermoplastic elastomer / rubber: 1, excellent anti-aging properties and good weathering, heat resistance; 2, excellent resistance to permanent deformation performance; 3, excellent tensile strength and high toughness and high resilience; 4, excellent environmental performance and reusable; 5, excellent electrical insulating properties; 6, a wide range of hardness; 7, a wide temperature range; 8, a variety of colors, there are transparent, translucent , light-colored series, coloring easy easy molding; 9, can be extruded or co-injection molding with PP, PA, PC, ABS, PS, PBT, PET, and other materials.

Transport equipment a road, bridge expansion joints; 2, road safety facilities, buffer crash parts; 3, container seals. Building materials 1, 2 power unit seal, construction joints, sealing strip 3, for drain seals, pour system control valves and other TPV slightly hygroscopic properties, should be added to dry, especially during the extrusion or blow Before processing, but also to be dried. Before the material is placed in the oven, the temperature should be raised to the first dryer 100 ℃. TPV is then held in the oven for 2-3 hours. Should avoid contact with high relative humidity environment, because the material will absorb moisture, so that the processing of products produced voids. If, after stopping a long time before re-starting the operation, should the extruder barrel remained of the raw material is discharged. In TPV before and after processing, the extrusion equipment should be thoroughly cleaned. Injection device or extruder barrel should be mechanically cleaned or replaced with a polyethylene or polypropylene completely emptied. 1) injection molding TPV melt viscosity than many ordinary thermoplastic material larger in the processing, the need to apply a larger injection nozzle, sprue, runners and gates, also need to use a high injection pressure and less fast injection rate, to improve the filling speed and to reduce the burr, and thereafter under relatively high pressure with a short holding time, so that the pouring spout is sufficient to freeze. Injection screw speed should be from 100 to 200 rev / min, back pressure in the mixing is not required to be as low as possible. 2) extrusion processing does not require vacuum sizing. Recommended an aspect ratio of 28 to 1 or greater ratio of the extruder. Usually single-stage screw ratio of 3 to 1 or so, if you need to use a combination of mesh, available in 20-60 mesh sieve. The melt temperature is preferably kept at the lower limit of the predetermined range, so that the best quality of the extruded product. 3) TPV blow molding machine requires the same operating conditions specified in injection molding and extrusion. Mold design, preform dimensions, processing cycle time, as well as uniform thickness and other blow molding processing factors have a great relationship with the geometry of the parts of the. Excessive heat will make the draw ratio of melt down should avoid overheating.
