Product Name: UHMWPE Texas Shengtong Rubber Co., Ltd. is China's largest supplier of ultra high molecular weight polyethylene products in the industrial sector of the UPE, with the most complete product grade UHMW-PE. Jiang special grade polymer that can be used to forming porous and filtration products can also be used as an additive in paints, coatings or material modification of the collective. UHMW-PE (ultra high molecular weight polyethylene) Overview: UHMW-PE is the English Ultra High Molecular Weight Polyethylene (UHMWPE) acronym. This is the highest quality polyethylene available for harsh working conditions and a variety of purposes. In many difficult conditions for the applicability of the application is very good. PE is divided into three categories: 1, low-density PE, medium density PE, low-density polyethylene high-density PE (less than 0.930 g / cc / less than 0.0334 lbs / cubic inch) medium density polyethylene (between 0.930 and 0.940 g / between cc / between 0.0334 and 0.0338 cubic inches) high density polyethylene (greater than 0.940 g / cc / greater than 0.0338 lbs / cubic inch. molecular weight of about 100,000) 2, the molecular weight of the high molecular weight high density polyethylene PE Ethylene (molecular weight greater than 200,000 less than 500,000). Such products are manufactured by a method using a catalyst made of two: one is a Ziegler method, this method using a titanium catalyst; the other is the Phillips method, this method using a chromium oxide catalyst. Both of these methods include techniques: carried out at different pressures suspending, dissolving, gas and condensed, under these conditions, the formation of linear macromolecules vinyl molecules by anionic polymerization. 3, ultra-high molecular PE strength ultrahigh molecular weight polyethylene (density greater than 0.940 g / cc, i.e., greater than 0.0338 lbs / cubic inch, a molecular weight greater than 1,500,000). Introduction: molecular weight polyethylene at 200,000 below the current yield is one of the largest plastic varieties, the most widely used. Wherein, LDPE, HDPE, and is known as the third generation are all part of an LLDPE polyethylene thermoplastics. Molecular weight of more than 1.5 million polyethylene, called "ultra-high molecular weight polyethylene (UHMW-PE)". Only the molecular weight of up to 150 million or more ultra-high molecular weight polyethylene (UHMW-PE), because of its excellent physical properties are widely used as engineering plastics. This ultra-high molecular weight polymers of different qualities to the public, which has 3 to 10 million molecular weight, high density polyethylene resin only 300000-500000. This difference is to ensure UHMWPE have sufficient strength, the other is not possible to achieve the low polymerized products with resistance to abrasion and impact resistance. UHMWPE using Ziegler-type catalyst efficiency low-pressure synthesis, ethylene, butadiene monomer in the role of a catalyst, polymerization of viscosity average molecular weight greater than 1.5 million engineering thermoplastics oxygen units. Processing requirements are particularly high purity ethylene monomer impurity control in parts per million. Product is a white powder, is generally 20-80 mesh, the solution viscosity of the polymer by the method to detect, thus calculating the intrinsic viscosity (IV) and molecular weight (MW) .UHMW-PE is defined according to ASTM weight average molecular weight ( MW). Typically, UHMW-PE material without additives, stabilizers and without sintering and forging. Under processing conditions, contained in the pressure maintaining the temperature at 392F hour and if at 0.5 tons / square inch or higher pressure conditions, may be solidified into a block, sheet or simple extrusion. Since the advent of this polymer, because of its variety of excellent performance, and attracted much attention. However, due to the special nature difficult to process, limiting its development and application. Until the late seventies, research institutions and large companies in developed countries began to realize the industrialization of the world's first industrialized American Allied Chemical Corporation, then the German company Hoechst, US Hercules Corporation, Mitsui Petrochemical Corporation, also put into industrial production . Thus the prelude to large-scale application of ultra-high molecular weight polyethylene. As countries continue to increase research efforts, and gradually developed a sintering, ram extrusion, screw extrusion and injection molding and other methods for large-scale application of ultra-high molecular weight polyethylene basis. Our success in 1964 was first developed and put into industrial production. Was limited conditions, the molecular weight of about 1.5 million, with the advancement of technology, the current product molecular weight of up to 1.5 million -600 million. Before the 1980s, the world's average annual growth rate of 8.5%, after the 1980s, the growth rate as high as 15% -20%. In China, the average annual growth rate of over 30%, is the "high-tech industries key field guide priority development" of "Ninth Five" program to promote the project. UHMW-PE high molecular weight gives it exceptional performance, which focused almost entirely on the merits of various plastics, polyethylene and other plastics ordinary unparalleled abrasion resistance, impact resistance, self-lubricating, corrosion resistance, absorb impact energy, low temperature, health, non-toxic, easy adhesion, easy to absorb water, less dense and so the overall performance, the fact is that there is not a pure polymer material combines so many excellent performance. Ultra-high molecular weight polyethylene (UHMW-PE) as the only new engineering thermoplastics, set in a variety of excellent performance: wear: in all current engineering plastics, UHMW-PE wear the best, most compelling attention, even more than many metal materials (such as carbon steel, stainless steel, bronze, etc.). UHMW-PE wear resistance than nylon (PA) 66 and polytetrafluoroethylene (PTFE) 4 times, 7 times higher than carbon steel, 20% higher than steel transport efficiency. UHMW-PE pipe, in highly corrosive conditions and high wear life is 4-6 times that of steel, but also improve the transmission efficiency of 20%, full of "energy saving, environmental protection, economic and efficient" superiority. Figure 1 is a UHMW-PE wear comparison with other materials, such high wear resistance that it is difficult to test the abrasion degree by conventional plastic wear testing method, and thus the use of mortar abrasion testing apparatus. Wear resistance is proportional to the molecular weight UHMW-PE, the higher the molecular weight, the better the wear resistance, appropriate cross-linking with peroxide can be used to enhance the wear resistance. Impact resistance: UHMW-PE plastic impact resistance ranks first, the impact strength of fame forefront in all engineering plastics. Whether strong external impacts, or internal pressure fluctuations, it is difficult to crack. Its impact resistance of nylon 66 is 10 times, 20 times polyvinyl chloride, polytetrafluoroethylene 8 times, 5 times the ABS, 2 times for the PC, and can be maintained at liquid nitrogen temperature (-196 ℃) high toughness, especially at low temperatures, the impact strength but the highest value. Figure 2 shows the impact strength for comparison with other engineering plastics, can be seen from Figure 2 the impact resistance is so high, that the test method is difficult to be broken by an ordinary impact damage, the impact strength improves with increasing molecular weight, reaches a maximum when the molecular weight of 1,500,000, and then continues to increase with the molecular weight gradually decreases. In addition, it even higher surface hardness after repeated shocks. Aging resistance: stable performance, good aging resistance, the ground can be buried underground for 50 years without aging. According to ASTM method (load 4.6kg / cm2), heat distortion temperature of 85 ℃, temperature up to 90 ℃, under special circumstances, to allow use at higher temperatures. UHMW-PE is an excellent toughness of the material, it is also very good low temperature resistance, low temperature at -269 ℃, still has some ductility, but no signs of embrittlement. However, a larger coefficient of linear expansion, thermal conductivity is poor, so the design products, to give full attention. UV linear or prolonged high temperature resistance can be achieved by the addition of UV stabilizers or antioxidants. Electrical properties: the volume resistance, up 1017-18SL-CM, (> 1E12ohm), the breakdown voltage up to 50KV / MM, a dielectric constant of 2.3. Over a wide temperature and frequency range suitable for use as a structural material in electrical engineering. Self-lubricating: has an extremely low friction coefficient (0.05-0.11) it is self-lubricating outstanding, it can be seen from the table the dynamic coefficient of friction under water lubrication is PA66 and POM 1/2, second only in the absence of lubrication conditions in self-lubricating best polytetrafluoroethylene (PTFE), when it is working to form a sliding or rotating, than steel and brass lubricant lubrication even better, so the cost performance in the field of tribology hailed as ideal Friction Materials.
