Its breakdown voltage is also very high, suitable for use as electrical accessories. It has good resistance to voltage and arc resistance, but it has high static electricity, and it is easy to be aged with copper. Weatherability Polypropylene is sensitive to ultraviolet light. Adding Zinc Oxide, two propionic acid, two propionic acid, cinnamate, carbon black?or?similar milk filler can improve its aging resistance. Calculation of the reference value of hydrophobic parameter (XlogP): 3.32, number 03, number of hydrogen bond donor: hydrogen bond acceptor: 34, number: 15, the chemical bond rotation tautomer number: 6, topological polar molecular surface area (TPSA): 29.5 to avoid strong oxidizing agent, chlorine, Potassium Permanganate closed, cool and dry place save, to ensure good ventilation. Characteristic Non-toxic, tasteless, small density, strength, stiffness, hardness of the hardness is better than low pressure polyethylene, can be used at about 100 degrees C. It has good dielectric property and high frequency insulation and is not affected by humidity, but it becomes brittle at low temperature. It is not wearable and aging. It is suitable for making general mechanical parts, corrosion-resistant parts and insulation parts. Common acid and alkali and other organic solvents, it almost does not work, can be used for utensils. Polypropylene has many excellent properties: 1. The relative density is small. It is only 0.89-0.91. It is one of the lightest varieties in plastic. 2, good mechanical properties, in addition to the impact resistance, other mechanical properties are better than polyethylene, good molding performance. 3, with high heat resistance, the continuous use temperature of up to 110-120 degrees. 4, good chemical properties, almost no water, and the vast majority of chemical drugs do not react. 5, pure texture, non-toxic. 6. The electrical insulation is good. 7. The transparency of polypropylene products is better than that of high density polyethylene. It has many advantages, but also has shortcomings. 1. The cold resistance of the products is poor, and the low temperature impact strength is low. 2, products are vulnerable to light, heat and oxygen in the use of aging. 3. The pigmentation is not good. 4, easy to burn. 5, poor toughness, high degree of static electricity, dyeability, printing and poor adhesion. The branched chain atoms of the random polypropylene are irregularly distributed on both sides of the main chain. See Figure three Polypropylene classification chart three EVA Increase the impact resistance of ethylene propylene rubber, EPDM, POE, EVA, SBS Improve transparency LDPE, ethylene propylene rubber, POE Improvement of pigmented polyamide, polyurethane, polyacrylamide, polyacrylate, polyester, polyvinylidene chloride, polyvinylidene two Improving gas tightness (gas barrier) polyamide and polyvinylidene chloride two Improved antistatic polyvinyl alcohol In the blending modification, we must pay attention to the compatibility between different polymers. When the two polymers with poor compatibility are mixed, third components which are compatible with the two polymers often are called compatibilizer. Such as polypropylene and nylon -6 compatibility is poor, single * machinery force can not mix the two evenly, then add a little like has been grafted with maleic anhydride two polypropylene, maleic anhydride and nylon two because -6 amide groups can occur chemical reaction, it can greatly improve the compatibility of -6 nylon and polypropylene. In the blending modification, we must notice that only when the heterogeneous system is formed, and the two polymers can be evenly dispersed, can we achieve the desired modification effect. EBS Packaging materials in plastic products occupy an extremely important position, according to statistics, the world's plastic for packaging accounts for about 35% of the total plastic consumption. The development of packaging plastics in China has been developing rapidly. The output increased from 190 thousand T in 1980 to 4 million 650 thousand T in 2003. It is expected to exceed 5 million 500 thousand T in 2005, over 6 million T in 2010, and more than 6 million 500 thousand T in 2015, accounting for about 13% of the total national packaging output. Polypropylene film From the point of view of the product, the packaging film accounts for more than 50% of the total amount of the packaging plastic. The biaxially oriented polypropylene (BOPP) film is one of the largest consumption areas of PP resin in China. In 2003, 86 BOPP production enterprises (123 production lines) were produced in China. The total production capacity is 1 million 400 thousand t/a, and 2 million t/a (138 production lines) in 2004. The output will exceed 1 million T. Domestic enterprises focus on improving product competitiveness, and have introduced a number of advanced BOPP production equipment. The width of the film is 8.3m, and the line speed is as high as 400~500m/min. According to China's existing BOPP film production capacity conversion, the annual demand for PP resin of nearly 2 million T, with high speed, so it should be extended PP special material, good transparency in the development of BOPP films, including attention, ethylene propylene copolymer used in supporting, in order to adapt to the introduction of new equipment of BOPP films. industrial production Chinese industry China polypropylene industrial production began in 1970s, after 30 years of development, has been basically formed and process the production of a variety of solvent, liquid phase bulk gas phase method, batch liquid bulk polymerization and gas phase method, large and small production scale production pattern of coexistence. China's large polypropylene production equipment is mainly imported technology, and the medium and small polypropylene production equipment are mainly made by domestic technology.
