as the existence of the short chain of polyethylene interferes with the crystallization of the main chain, the increase of the short chain will destroy the crystallization&reduce the density. the homopolymer high density polyethylene (hdpe) contains very few short branched chains, so it has high crystallinity&high density.、pvc is the main source of dioxin. dioxin (tcdd), two oxygen (miscellaneous) the most deadly dioxin in the family is a kind of substance, as everyone knows the carcinogens&catabolic hormones&a toxic compound, has a great harm to human&animal. when pvc production, recycling&scrap in the incinerator,/pvc products in the combustion accident such as garbage landfill, will produce dioxin.、pa66对玻璃添加剂的产品为275~280℃。熔化温度应避免高于300℃。注塑压力?通常在750~1250bar?取决于材料和产品设计。密度?pa66密度1.15g?cm3。熔点252℃。脆化温度-30℃。热分化温度大于350℃。接连耐热80-120℃,平衡吸水率2?5?。;收缩率流动:3.20mm横向流量:2.00mm流量:2.00mm吸水率23°c,24hr拉伸模量(23°c)31001400抗张强度屈服,23°c屈服,23°c8.3023°c8.2055.0伸长率8.3064.0屈服,23°.0%屈服,23°.525%断裂,23°c50>300%断裂,23°0>断张率(23°c)20>拉伸蠕变模量1hr14001000hr930pa66弯曲模量-40°c3200mpa?23°c28001210mpa?77°c700?121°c500?23°c28001200mpa介电常数?23°c,100hz4.10?23°c,1khz4.00?23°c,1mhz3.70?23°c,100hz3.80?23°c,1khz3.9023°c,1mhz3.60makrolon3156pcbayermaterialscienceag、although other melting processes can be used, the vast majority of ppa resins are processed by traditional injection molding. pre drying ppa raw material to a humidity level below 0.1%&then loading it into a thermally sealed metal village bag/box. these containers ensure that ppa raw materials need not be dried before processing. the moisture level acceptable to the processing process is 0.15%/lower. the processing of wet resin can reduce the molecular weight&cause the loss of mechanical properties. using a desiccant et dryer, it is easy to dry the resin to the dew point humidity of 25 f/even lower at 175 f. the drying time depends on the amount of water absorbed, usually within the range of 4 - 16 hours.、pa66 plastic material is a translucent/opaque white bag/yellow granular crystalline polymer、pmma pmma、2) the molecular bond of ppo is very rigid,&the glass conversion temperature is high,&it is not easy to orientate, but it is difficult to relax after forced orientation. therefore, the residual internal stress in the product is high,&it should be treated after the post.、injection grade, powder, feature&use with 450g、the mechanism is that the low bonding temperature is very low at the end of the flow at the end of the flow, so that the combination of the two strand flows is not close.、it is widely used in machinery, instrumentation, automotive parts, electronic&electrical, railway, household appliances, communications, spinning machines, sports leisure products, oil pipes, tanks&some precision engineering products.、injection enhancement grade, 15% carbon fiber, features&uses with the same pdx79737、tpu油墨具有光洁的外观,良的遮光性及耐醇、附着力强等特点,主要适用于tpu等塑胶的表面装饰。如手机、电脑、鞋、轿车皮椅、沙发、皮具、、充气tpu制品、雨伞、雨衣等tpu油墨用于金属、玻璃上,附着率差,易掉漆。、contract month: 1 to december、11) poor fluidity, which is similar to newton fluid, the viscosity is more sensitive to the temperature,&the thickness of the product is generally above 0.8 mm. it is very easy to deco-e,&the corrosion gas is produced when deco-ing. the molding temperature should be strictly controlled. the mold should be heated&the flow resistance of the feed system should be small.
、optical lighting: the right&left eyepiece for large lampshade, protective glass, optical instrument&so on. it can also be widely used for transparent materials on aircraft.、poe应用范围主要用于改性增韧pp、pe和pa在汽车工业方面制作杠、挡泥板、方向盘、垫板等等。电线电缆工业上耐热性和耐性要求高的绝缘层和护套。也用于工业用制品如胶管、输送带、胶布和模压制以及家用电器、文体用品、玩具等,以及包装薄膜,尤其适合低烟无卤阻燃料;化妆品、等软管包装;运动鞋底发泡中底、大底等;阻燃母料;拉伸膜、缠绕膜、各类保鲜膜;也用于工业压制品如胶管、输送带、胶布和模压制品等。、4, the content of vinyl acetate is 5%~45%, the main products are thin film (including agricultural film)&sheet, injection molding, molded products, foaming products, hot-melt adhesives&so on.、pc/abs alloy, pc&abs blends can combine the excellent properties of pc&abs, improve the heat resistance, impact&tensile strength of abs, reduce the cost&melt viscosity of pc, improve the processability,&reduce the sensitivity of product internal stress&impact strength to the thickness of products. the rapid development of pc/abs alloy, the global output of about 800 thousand tons / year, the worlds major companies he developed new varieties of pc/abs alloy, such as flame retardant, glass fiber reinforced, electroplating, uv resistant varieties, espelly widely used in the automotive industry, is also widely used in computers, copiers&electrical&electronic components. china has started a research&production of pc/abs alloy materials such as shanghai jieshijie company has been applied to automobile decorative parts, lamp shell&heat appliance shell; development institute of the chinese academy of applied chemistry changchun high heat resistance, high heat resistance&high impact resistance&high heat resistance of the three grade pc/abs alloy material has been a number of domestic automobile manufacturing the company used for front decorative board, instrument panel&box cover&other spel material goods. lanzhou university study in pc/abs blend with a high pressure polyethylene compatibilizer, the mixture obtained good flowability&low temperature toughness&modulus is almost not affected, for the production of sheet; domestic researchers in order to reduce the pc/abs interface between two phases, adding impact agent mbs in pc&abs, the degree of the impact of air alloy can achieve very high value, pc/abs/mbs appearance is ivory white, uniform texture, feel good. 、makrolon8025pcbayermaterialscienceag、back pressure
