PA66//PA320G3/計(jì)時(shí)器

東莞市千泰塑膠原料有限公司為您提供pa66//pa320g3/計(jì)時(shí)器。pa66//pa320g3/計(jì)時(shí)器
pa66//pa320g3/計(jì)時(shí)器【---】long term supply of pp impact polypropylene main commer---l uses are used in automobiles, household goods, appliances, injection molding parts. its impact resistance, low density, coloring ability&processing properties make it an ideal material. the medium impact resin grade with high melt flow rate has a high flow performance, which is espe---lly useful in injection molding of large components such as automotive panels.
resin with high impact resistance with low melt flow rate (less than 2), can be transformed into a thin film puncture resistance excellent, this kind of film impact resistance&resistance to steam sterilization ability, suitable for disposable medical waste bag. the extruded sheet can be machined into large&thick parts by a hot forming process, such as a guard plate in the automotive industry&a car rear luggage liner.
pa66 nylon 66 salt was prepared by acid&amine preparation of nylon two yuan, need to strictly control the ratio of raw materials such as molar ratio, in order to get a high molecular weight polymer, therefore, must be put in the production of adipic acid&hexanediamine mixture made of nylon 66 salt. nylon 66 salt are prepared respectively the solution&the hexamethylene diamine adipate at 60 deg c above the mixing&salt precipitation, filtering, alcohol washing, drying, zui preparation of aqueous solution of around 63%, for the use of polycondensation.
pc, in order to meet the high performance of electronic shell material toughness, strength, heat resistance&other requirements. the application of these materials in electronic&electrical appliances shell piece, has the following advantages of other materials can not be replaced: polycarbonate can be
1) superior impact resistance, impact strength in thermoplastic plastic top;
2) good finishing&the covering film adhesion;
3) high dimensional stability;
4) install the components into a whole;
5) design&manufacture of flexible application;
6) low expansion coefficient, low thermal expansion coefficient.
rapid growth of pom market, based on chinese pom production is relatively weak; in addition, pom is the capital&technology intensive materials such as chemical products, chinese huge market attracted foreign attention, other country has been trying to market its products occupy chinese, to transfer technology, the technical level of chinese pom the increase is slow, can not meet the needs of users; there is a long time, china economy&enterprise operating system does not conform to the rules of market economy, enterprises can not get enough funds in a timely manner, restricts the development of pom production.
pbt is the same with the engineering plastics in the industrialized zui late development of a variety of zui fast, it has become the bright younger generation of engineering plastics, is that it has excellent comprehensive performance, compared with the processing&good performance / price, therefore pbt plastic although until the 70s industrial production, but soon selling market. this is a zui five engineering plastics development quickly.
