By Huayun plastic raw materials Co., Ltd. raw materials agent, low density polyethylene molecular chain has long and short branched chain. Low crystallinity, molecular weight of 50 ~ 50 million, it is a milky white translucent wax solid resin, non-toxic. It can work at 60 鈩� ~ - 80 鈩� and has electrical insulation (especially high-frequency insulation). LDPE has poor mechanical strength, low heat resistance, poor environmental stress cracking resistance, adhesion, adhesion and printability, and needs to be processed on the surface The adhesion and printability can be improved after chemical erosion and corona treatment. Water absorption is very low, almost no water absorption, chemical stability, such as acid, alkali, salt, organic solvents are more stable. It has high permeability to CO2 and organic odor, but poor permeability to water vapor and air. It is easy to burn and looks like paraffin when burning; it is easy to be aged and degraded under sunlight and heat, and changes color from white to yellow to brown, and finally turns black, and its perbance decreases or cracks. If a certain amount of antioxidant and ultraviolet absorbent are added, its perbance can be improved, and crossbing under chemical crossbing agent or high-energy irradiation can improve softening point, temperature resistance, rigidity, solvent resistance, etc.
According to the types of comonomers, LLDPE can be divided into three types: C4 (butene-1), C6 (Hexene-1) and C8 (octene-1). Among them, butene copolymer is the LLDPE resin with high production, while hexene copolymer is the LLDPE variety with fast growth. In LLDPE resin, the typical amount of comonomer is 5% - 10% by weight, and the average amount is about 7%. Metallocene based LLDPE plasticizers (mLLDPE) have an average comonomer content of more than three times that of conventional LLDPE.
Linear low density polyethylene (LLDPE) is a copolymer of ethylene and a small amount of higher 伪 - olefins (such as butene-1, Hexene-1, octene-1, tetramethylpenten-1, etc.) by high pressure or low pressure polymerization in the presence of catalyst. The density is between 0.915 and 0.940 g / cm3. However, according to ASTM d-1248-84, the density range of 0.926-0.940 g / cm3 is medium density polyethylene (MDPE). The new generation LLDPE has expanded its density to plastic (0.890-0.915 g / cm3) and elastomer (< 0.890 g / cm3). However, the American Plastics Industry Association (SPI) and the American Plastics Industry Council (APC) only extended the scope of LLDPE to plastids, excluding elastomers. In the 1980s, Union Carbide and Dow chemical called their early plastic and elastomer resins very low density polyethylene (VLDPE) and ultra low density polyethylene (ULDPE).
The molecular structure of conventional LLDPE is characterized by its linear main chain, with little or no long branches, but some short branches. The absence of long branched chains makes the polymer more crystalline.
Generally, LLDPE resins are characterized by density and melt index. Density is determined by polymer
Low density polyethylene (LDPE) is suitable for various molding processes of thermoplastic molding. It has good molding processability, such as injection molding, extrusion, blow molding, rotary molding, coating, foaming process, thermobing, hot air welding, hot welding, etc. LDPE is mainly used for film products, such as agricultural film, ground covering film, agricultural film, vegetable greenhouse film, etc.; packaging film such as candy, vegetables, frozen food, etc.; liquid packaging film (milk, soy sauce, juice). The main products are: bean curd, soybean milk; heavy packaging bag, shrink packaging film, elastic film, lining film; construction film, general industrial packaging film and food bag. LDPE is also used for injection molding products, such as small containers, lids, daily products, plastic flowers, injection stretch blow molding containers. Medical appliances, medicine and food packaging materials, extruded pipes, plates, wire and cable cladding, profiled materials, thermobing and other products; blow molding hollow molding products, such as food containers, dairy products and jam, cosmetics, chemical products containers, tanks and so on.
