Molding processing of ultra-high molecular weight polyethylene in the world developed countries account for more than 60% of all molding method, we accounted for more than 85%, with the deepening of the research on ultra-high molecular weight polyethylene, equipment improvement, the improvement of injection molding process, mold molding in proportion of ultra-high molecular weight polyethylene all molding decline gradually.
Because of ultra-high molecular weight polyethylene performance is very excellent, continuous increase in the amount of each year, expanding the scope of its application.
the POB thermal decomposition temperature is 530 ℃, 300 ℃ in use for a long time. With high thermal conductivity and low linear expansion coefficient and under 325 ℃, the linear expansion coefficient is almost constant. Good electrical insulation, breakdown voltage of the POB over PI and fluorine plastic, due to the high crystallinity, POB make it has high dielectric constant and low dielectric loss. POB for all of the aliphatic and aromatic solvents and oil has excellent ability of resistance to both, but will be concentrated sulfuric acid and sodium hydroxide. Polyphenylene esters of radiation resistance is also very good, after 10 bgy cobalt radiation, its mechanical strength still can maintain 100%.
because of the high molecular weight polyethylene, melt viscosity, melt flow rate is almost zero, so to add to the great difficulty in forming process. Ultra-high molecular weight polyethylene early mould pressing and forming method is mainly for the production of large plate and a variety of small products. Using mold molding in we are now able to produce 6700 mm long, 1300 mm wide, the thickness of 6 - Ultra-high molecular weight polyethylene plate 150 mm oversize.
the POB good weatherability, in artificial accelerated aging on the 1000 h test, the strength of the basic remain unchanged. Polyphenylene esters with teflon to any blending ratio, because of the POB normally just like metal or thermosetting plastic molding and processing methods, thus with PTFE blend when using the dry mixing method, and then forming. Polyphenylene esters in machinery and equipment, electronic appliances and instrument parts and aviation is a high applicability.
with the progress of science and technology and the oil and the development of material science, the application of plastic is more and more widely, in the national economy occupies an important position in the production and daily life. Because plastic as the engineering material with many other materials incomparable excellent features, become an indispensable century materials in all walks of life, has a broad application prospect, in some areas with plastic instead of steel is the trend of social development, is a plastic era is coming.
POB relative density is 1. 45, bibulous rate is about 0. 02%. In a large temperature range has the very high rigid, resistant to compression creep, easy processing, injection tooling at the same time has a high load capacity, good self-lubrication, and steel friction coefficient is 0. 3, after adding 20% PTFE in POB, in the absence of lubrication of PV value of 2500 KP. M/s when more than empty bronze bearing lubrication of PV value.
ultra-high molecular weight polyethylene is a new kind of engineering plastics, ultra-high molecular weight polyethylene in present engineering plastics and integrated performance is very good, so called magic plastic, some countries have been widely used in textile, paper, packaging, agriculture, mining, construction, sports and other fields. Because of ultra-high molecular weight polyethylene is a new kind of engineering plastics, appear relatively late people know relatively little of them.
