PP J108M ╅PBT the excellent mechanical properties of long-term supply, high mechanical strength, fatigue resistance and good dimensional stability. Creep is also small, and these properties do not change very much at elevated temperatures. The consumption of energy is low, the production of PBT Zui in engineering plastics, the worldwide energy shortage, has very important significance. C. excellent heat aging resistance, UL temperature index enhanced up to 120~140 DEG C, in addition, the outdoor long-term aging is also very good. The good solvent resistance, no stress cracking. ABS molding temperature, heat resistant resin in electroplating grade etc. grade requirements temperature slightly higher (210 - 2501) to change the chopsticks melt filling difficulty or electroplating benefit performance, for general purpose, flame retardant, impact resistant ABS resin and low temperature, to prevent the occurrence. or harmful to the physical and mechanical properties. EVA because of the molecular chain into vinyl acetate monomer, thereby reducing the high crystallinity, improved toughness, impact resistance, filler compatibility and heat sealing performance, is widely used in foam material, functional films, packaging mold, hot melt adhesive, wire and cable and toys and other fields. Is is widely used in foam material, functional films, packaging mold, hot melt adhesive, wire and cable and toys and other fields. TPE may cause undesirable phenomenon processing method for product mold variant cooling time is too short, the product failed to extend the cooling time enough cooling mold too fast, slow down the speed of opening the strong pull of variant product structure defects modify mold temperature is too high, the product is not in place to reduce cooling mold temperature product mold cracking temperature is too low or too low mold temperature increase the barrel temperature and die temperature draft ejector stroke is not enough or improper way to modify the mold gate is too small to modify mold angle modification of die PA66 etc fastness.Skid resisting and save labour, east to process and color, have widely designspace. oil series (Eeay-paintingseries) application of GP410 GP420GP430: all kinds of toys, daily necessities, such as oil, used to replace the PVC. [title] long term supply of PP features odorless, tasteless, non-toxic white granulated products or powder products, relative density of 0.90 ~ 0.91. Melting point 164~167 DEG C. With excellent mechanical properties, heat resistance, electrical insulation, chemical stability, and most chemicals do not work. But the light fastness is bad, easy to aging, low impact strength at low temperature, poor dyeing, need to add additives, blending, copolymerization and other ways to improve. Insoluble in water, no water absorption, can be boiled in water, disinfection at 130 degrees, easy processing molding. Suitable for making general mechanical parts, corrosion resistant parts and insulation parts. PE polyethylene is a simple polymer with a simple structure of Zui, and is also a widely used Zui polymer material. It is connected by a repeating - CH2 - unit. Polyethylene is formed by addition polymerization of ethylene (CH2=CH2). PA66 applications Widely used in the manufacture of machinery, automobile, chemical and electrical apparatus parts, such as gear, pulley, roller, roller shaft, pump impeller, fan blades, high pressure sealing gasket, circumference, seat, bushing, handles, supporting frame, inner wire etc.. Casting condition Injection pressure Usually in 750~1250bar, depending on the material and product design. Injection rate High speed (for reinforced material should be slightly lower). Runner and gate: gate position is very important due to the very short solidification time of PA66. The gate hole diameter should not be less than 0.5*t (t here is the plastic part thickness). PC, plastic, scientific name is polycarbonate, is a polymer molecular chain containing carbonate group, according to the structure of the ester can be divided into aliphatic, aromatic, aliphatic aromatic and other types. Because aliphatic and aliphatic aromatic polycarbonates have lower mechanical properties, they limit their application in engineering plastics. At present, only aromatic polycarbonate has been industrialized production. As a result of polycarbonate structural particularity, now has become the five major engineering plastics growth rate of Zui fast general engineering plastics. Apple iPod and iBook shell also use this plastic raw material is oil due to impact resistance is colorless and transparent and excellent are widely used in bottle production, for the production of Medical... For airlines, airlines... For packaging, for electronic and electrical appliances... For optical lens for optical disc based... "In the car in PC..... The fatigue strength of POM is very outstanding, 10 alternating load, the fatigue strength of 35MPa, PA and PC, only 28MPa. Creep and PA POM similar, at 20 C, 21MPa, 3000h is only 2.3%, but little affected by temperature. The friction coefficient of POM is small, weatherability, good wear resistance, POM is not good, long-term under ultraviolet light, the degradation of mechanical properties, surface pulverization and cracking. Forming crystalline material, the melting range is narrow, melting and solidification fast, the material temperature is slightly lower than the melting temperature, that is, crystallization, medium mobility, moisture absorption is small, without drying treatment.
