Detailed Product Description: | PPO plastic materials performance 1, the white particles. Good overall performance, can be used in 120-degree steam, electrical insulation, water is small, but there is a tendency to stress cracking. Noryl eliminate stress cracking. 2, there are outstanding electrical insulation and water resistance, better abrasion resistance and electrical properties, good dimensional stability. The dielectric properties of plastics in the first place. 3, MPPO for modified materials PPO and HIPS blends prepared, currently on the market are such materials. 4, a higher heat resistance, glass transition temperature of 211 degrees, melting point of 268 degrees, heated to 330 degrees have a tendency to break down, the higher the content of PPO better heat resistance, heat distortion temperature up to 190 degrees. 5, good flame retardant, self-interest, and HIPS mixed with moderate flammability. Lightweight, non-toxic and can be used in the food and drug industries. Poor light, for a long time in the sun will change. 6, the modification can be blended with ABS, HDPE, PPS, PA, HIPS, glass fibers and the like. PPO plastic material properties A, PPO plastic materials, non-toxic, transparent, relatively low density, excellent mechanical strength, resistance to stress relaxation and creep resistance, heat resistance, water resistance, water vapor resistance, dimensional stability. B, in a wide temperature range of the frequency-dependent electrical properties, not hydrolyzed, low mold shrinkage, there are self-extinguishing flame retardant, resistant to inorganic acids, alkalis, poor resistance to aromatic hydrocarbons, halogenated hydrocarbons, oils and other properties, Easy swelling or stress cracking. C, it has a rigidity, heat resistance, flame retardant, high strength and excellent electrical properties and so on. D, the ether also has a wear-resistant, non-toxic, resistant to pollution. E, the dielectric constant and dielectric loss PPO plastic materials in engineering plastics is one of the smallest species, virtually unaffected by temperature, humidity, and can be used for low, medium and high-frequency electric fields. F, PPO load deformation temperature up to 190 ℃, brittle transition temperature of -170 ℃. G, the main drawback is poor melt flowability, molding difficult. PPO plastic materials molding process l) non-crystalline materials, moisture small, PPO water absorption is very low, but the water will make the product surface silver, bubbles and other defects, for which the raw material can be placed in an oven at 80 ~ 1OOC applicants, dried 1-2h after use. Molecular bond 2) PPO of rigid, high glass transition temperature, the orientation is not easy, but it is difficult to force the orientation relaxation. So the higher the residual stress products, generally after going through treatment. 3) PPO amorphous material in the molten state is close to Newtonian fluid rheology, but with increasing temperature the greater the degree of deviation from Newtonian fluid. 4) the melt viscosity of PPO large, so should improve the processing temperature, and appropriately increase the injection pressure to increase the filling capacity. 5) PPO back reusable material, usually repeated 3 times, its performance is not significantly reduced. 6) should be used for PPO melt screw injection molding machine nozzle using the straight-better, pore size of 3-6mm 7) in the PPO injection molding, should take the high-pressure, high-speed injection, holding pressure and cooling time is not too long. 8) the mold sprue should adopt the use of a larger taper or pull material hook runner with stubby as well. 9) gate should adopt the direct type, or flat fan-shaped, when using the needle should be appropriately increased gate diameter, can be used for long runner runner structure. Mold Shrinkage 10) PPO small, typically 0.2% to 0.7%, and thus dimensional stability and excellent performance products. 11) poor mobility, for a similar Newtonian fluid, the viscosity is sensitive to temperature, product thickness of 0.8 mm or more. Easy to decompose, corrosive gas decomposition. Strictly control the molding temperature, mold should be heated, gating system flow resistance should be small. Water absorption 12) polyphenylene ether low around 0.06%, but the amounts of moisture will cause the product surface is not smooth, silver and other phenomena, it is best for drying, the temperature not higher than 150 degrees, or color change. 13) polyphenylene ether molding temperature of 280-330 degrees, modified polyphenylene ether molding temperature of 260-285 degrees. PPO plastic materials molding process melt temperature :270-290 ℃ cylinder thermostat: PPO has a high heat resistance, thermal decomposition temperature of 350C, 300C or less without significant thermal degradation phenomena. Typically, the temperature control in the barrel 260 ~ 290C, the temperature of the nozzle cylinder temperature below about lOC. Mold temperature: As PPO melt viscosity, should result in a higher mold temperature molding. Typically, the mold temperature control in 100 ~ 15OC. When the mold temperature below 1OOC, thin-walled plastic parts and less prone to full stratification; while higher than 15OC, prone to bubbles, silver, warping and other defects. Injection pressure: increasing the injection pressure is conducive to filling the melt, generally at an injection pressure control pressure at 100-14OMPao: injection pressure 40% -60% backpressure :3-10 MPa (30-100bar) Injection speed: The article has a long flow channel requires rapid injection; but in this case, to ensure a sufficient air-permeable membrane. Screw speed: medium screw speed equivalent to a linear velocity of 0.6m / s measured stroke :0.5-3 .5 D residues feeding amount :3-6mm, depending on the diameter of the screw and the metering stroke. Pre-drying: drying at temperature 110 ℃ 2h. Recovery: renewable materials processing, as long as the material back no thermal degradation. Shrinkage: 0.8% -1.5% gate system: small products using point or submarine gate, sprue or otherwise using wafer gate; runner machine down time can be shut down the heating system; bottom screw back pressure state, the operation several times measurement cycle, the same as the operation of the extruder barrel emptied. Barrel Equipment: Standard screw, check ring, through the nozzle. Edit this paragraph PPO plastic materials applications 1, suitable for the production of heat-resistant parts, insulating parts, less wear resistant parts, transmission parts, medical and electronic components. 2, can be used for high temperature use of gears, blades, valves and other parts can be replaced by stainless steel. 3, can be made screws, fasteners and connectors. 4, motors, rotors, chassis, electrical transformer parts. 5, PPO and MPPO mainly used in electronic appliances, automobiles, household appliances, office equipment and industrial machinery, etc., use MPPO heat resistance, impact resistance, dimensional stability, abrasion resistance, spalling. 6, can be painted and electrical properties, used for car dashboards, radiator lattice, speaker grille, consoles, fuse boxes, relay boxes, connectors, wheel covers. 7, the industry is widely used in the manufacture of electrical and electronic connectors, coil winding shaft, mechanical parts shields, switch relays, tuning equipment, large electronic displays, variable capacitors, battery accessories, microphones and other components. 8, used in televisions, cameras, video tape, tape recorders, air conditioners, heater, rice cookers and other household appliances spare parts. Can be used as a copier, computer systems, printers, fax machines installed substandard parts and components. 9, another camera can do, timers, pumps, blower housing and parts, silent gears, pipes, valves, surgical instruments, sterilizers and other medical equipment parts. 10, a large blow molding large parts such as automotive do spoilers, bumpers, low foam molding suitable for production of high rigidity, dimensional stability, excellent sound absorption, the internal structure of large, complex products, such as various machine casing, base , internal support, design flexibility, lightweight products |
