Ultra-high molecular weight polyethylene rod (white)
English name (also known as thermoplastic engineering plastics with a molecular weight higher than 10,000. It has a molecular chain length that is twice that of high-density polyethylene, and a longer molecular chain (more The main advantages given by high molecular weight are toughness, wear resistance and stress crack resistance. Since it is a type of polyethylene, it also has lubricity, chemical resistance and general excellent electrical properties. Its successful development is generally regarded as One of the top ten scientific and technological achievements of the century.
Product Features
Excellent wear resistance, good low-temperature impact resistance, self-lubricating, non-toxic, water-resistant, chemical-resistant, heat resistance better than average, disadvantages It has low heat resistance (heat deformation temperature) and poor processability. Its outer surface hardness, rigidity, and creep resistance are not as good as those of ordinary engineering plastics. Its expansion coefficient is relatively large. It has poor fluidity and extremely high viscosity in the molten state. It is rubber-like. Viscoelasticity, in the early days, could only be formed by pressing and sintering methods, but now it can also be processed by extrusion injection molding and blow molding.
The mechanical properties are higher than ordinary high-density polyethylene. It has outstanding impact resistance and stress cracking resistance. High temperature creep resistance, low friction coefficient, self-lubrication, excellent chemical corrosion resistance, fatigue resistance, noise damping, nuclear radiation resistance, etc.
Using temperature ~ ℃. Good cold resistance, can be used at ℃. For products with a density of 10,000 and a molecular weight of 10,000, their tensile strength at break, elongation at break, flexural elastic modulus, and cantilever notch impact are constant. Abrasion (method).
Application fields
Ultra-high molecular weight polymer Ethylene rods can replace carbon steel, stainless steel, bronze and other materials for use in textile, paper, food, machinery, transportation, medical, coal, chemical and other sectors. For example, in the textile industry, technical shuttles, shuttle rods, gear connections, sweeping rods, buffer blocks, eccentric blocks, rod bushings swing Result and other impact-resistant wear parts. In the papermaking industry, it is used as box cover, wiper blade, sealing parts, joints, transmission machinery seals, shafts, deflectors, scrapers, filters, etc. In the transportation industry, it is used as the lining of hoppers and silos for powdery materials.
Ultra-high molecular weight polyethylene rods
Can be used to make various mechanical parts, including gears, worm gears and worm bearings for food machinery. In the chemical industry, they are used to make pump valves, baffles and filter plates. In medicine, they can also be used in the heart Short surgical parts of valves, artificial joints and birth control implants. In sports, it can be used as skating floor, ball track, snowboard and sled parts.
The application range is similar to polyamide and polytetrafluoroethylene, and its wear resistance exceeds that of carbon steel. Gear bearings, bearings, star wheels, valves, pumps, guide rails, seals and packings, equipment linings, sliding plates, artificial joints, etc., fibers for bulletproof vests, ropes, etc.
Ultra-high molecular weight polyethylene has many excellent properties, but there are very few such excellent engineering plastics. Some people know its existence. This is mainly due to insufficient research on the melt characteristics of ultra-high molecular weight polyethylene in the past, and the processing method basically remains in the backward pressing-sintering process. In recent years, with the processing of ultra-high molecular weight polyethylene With the continuous development of technology, its products have been successfully applied in many fields.
