EVA HH6410M∑Long term supply of PBT in the field of automobile manufacturing, PBT is widely used in the production of bumper, carburetor components, fenders, spoiler, spark plug terminal board, fuel system parts, instrument panel, auto ignition, accelerator and clutch pedal etc.. The rapid growth of PBT market demand. In the country on imported products anti-dumping case, with the financial crisis and recession caused by the different car market unusually hot, the government encourages automobile consumption policies and cars to the countryside and other activities is played an important effect. With the rapid demand for plastics in automotive industry, China plastic industry and automobile industry has formed a prosperity, a loss for both sides of the potential. The plastics industry has turned its focus to PBT plastics, using lighter, stronger and better auto parts to ease the high price of oil. POM, the impact strength is higher, but the impact is less than ABS and conventional PC / / POM; it is sensitive to the gap, the gap can make the impact strength decreased more than 90%. The production process of different /POM can produce poly formaldehyde and formaldehyde copolymer were different. Homopolymer should be made of polyoxymethylene. First of all, it is necessary to manufacture anhydrous formaldehyde. The main method is firstly hydrated formaldehyde (methylene glycol, HCH (OH)) reaction of formaldehyde and shrinkage (Er Yiyang (OC H) methane, CH), then the mixture of methylal and water by extraction?or?vacuum distillation dehydration, formaldehyde and the heating way to release the methylal. At this time, formaldehyde was initiated by anionic catalysis, and then stabilized homopolymerization was obtained by blocking treatment. To produce formaldehyde copolymer acetal copolymer, put into three formaldehyde oxygen heterocyclic hexane (especially 1,3,5- three 4 dioxane, also called triformol). FUJITSU is the use of PC material significantly, many models are used in this material, but also the whole shell by using the material. No matter from the surface?or?from the sense of touch, "PC -GF feels like metal materials. If there is no mark in the notebook computer, it can be thought of as an alloy if it is not carefully observed from the outside surface. Polycarbonate is also used to make lunar astronauts helmet masks. The Apple Corp's iPod music player and the iBook laptop shell are also made of polycarbonate. Because of its clarity and toughness, producers and buyers of food stores prefer polycarbonate fibers. When compared to silicone glass, polycarbonate fibers are lightweight and highly brittle. Polycarbonate fibers are often used in disposable plastic bottles and reusable plastic bottles. The chemical properties of /PC and weak acid resistant polycarbonate plastic, resistance to neutral oil. Polycarbonate is not resistant to ultraviolet light?or?alkali. The physical properties of /PC plastics, the proportion of 1.18-1.20 g / cm3 molding shrinkage rate: temperature: 230-320 degrees 0.5-0.8% molding drying conditions: 110-120 DEG C for 8 hours can be used for a long time at -60~120 deg.. PA6 glass fiber reinforced polyamide material according to the characteristics of products requires the addition of glass fiber content in the range of 5-60%, this kind of material has good strength, heat resistance, excellent impact resistance, good dimensional stability and low warpage. In order to meet the requirements for use in industrial products, enhanced polyamide material should meet the following requirements: 1). Excellent strength and durability, rigidity and heat resistance combined with excellent performance. 2) coloring excellent surface appearance, perfect, can be applied to the structure forming complex, and help developers to design new style 3). Good processability, fluidity and excellent thermal stability of the material processing more relaxed conditions, the plastics miniature.
