詳細內(nèi)容：PC BN-8120R∮PC BN-8120R PC BN-8120R∮PC BN-8120R PA66 plastic material is a translucent or opaque white bag or yellow granular crystalline polymer PA66 green fiber reinforced material It has plasticity. The density of 1.10-1.14 (g/cm3); tensile strength (MPa) 60. 0-80.0; Rockwell hardness 118; the melting point of 252 DEG C; embrittlement temperature -30; thermal decomposition temperature greater than 350 DEG C; continuous heat 80-120 DEG C; impact strength (kJ/m2) of 60-100; the static bending strength (MPa 100-120); Martin (c) 50-60; bending resistance the elastic modulus (MPa) 2000~3000; volume resistivity (CM) 1.83 * 1015; balance absorption rate is 2.5%; a dielectric constant of 1.63. Chemical formula: [-NH (CH2) 6 - NHCO (CH2) 4CO]n - corrosion resistance to acid, alkali, most inorganic saline solution, halogenated alkane, hydrocarbons, esters, ketones, etc. PA66 has a high melting point in polyamide. At the time of product design, the contraction rate of a PA66 is between 1%~2%. Nowadays, there are many circulation on the market, which can also achieve the physical properties of raw materials, and the price is also much cheaper than raw materials, which saves a lot of money to merchants. PBT characteristics; The non - enhanced grade is strong, flexible and resistant to brittleness. The 94HB and self extinguishing grade (94-V-0, V-2), which have UL specifications, have the highest electrical properties in thermoplastic plastics. The water absorbability is very low, it is used for a long time in a wide range of temperature and humidity, and it can also maintain excellent electrical properties. The surface of the molded product is very smooth and has a low coefficient of friction. Because of the small friction consumption, it is suitable for the use of friction wear performance. The use of the size of the process is very small, and is a very good high trust material in the forming stability and dimension precision. It has excellent long-term chemical resistance. At room temperature, there is almost no decline in performance in long time soaked in drugs other than strong base. Not only the non - enhanced grade, the enhanced type of fluidity is also very good, good molding processing. By using the technology of phase fusion with other polymers, a high molecular alloy has been developed to meet the requirements of various properties. PC/PS alloy The alloy is partially compatible, amorphous / amorphous. Join in the PC PS PC can reduce the activation energy of viscous flow, so as to improve the processability of PC, adding a small amount of PS can make the PC melt viscosity decreased significantly, PS in PC can also play the role of rigid organic filler, PC and PS are transparent material, the two refractive index is very close, because the PC/PS alloy has good optical properties of transparent. The composition of PC/PS alloy has great influence on the mechanical properties, thermal properties and processability of the alloy. With the increase of PS content, the fluidity of PC/PS system increases, hardness, tensile strength and impact strength increase, while the thermal deformation temperature decreases. When the PS content is at a certain value, the impact strength and the tensile strength are maximum. Therefore, a suitable ratio of PC and PS can be used to produce a high performance PC/PS alloy. In addition of Compatibilizer on the properties of PC/PS blends have a greater impact, usually by grafting styrene styrene, caused double bond in the PC terminal, get the graft polymer effective compatibilizer for PC/PS blends, can greatly improve the compatibility of PS and PC, this material is suitable for the production of CD etc.. The application range of PC/PS alloy continues to expand, new varieties are emerging, such as the PC/PS Novally x alloy in Japan launched 7000, like ABS, easy to paint and ink printing; Japanese Light Petrochemical launched PC/PS flame retardant alloy series is compared with halogen, flame retardant ABS, has the characteristics of high toughness, good fluidity, high rigidity, flame retardant good.
