you can also create calcium plastic packaging and furniture, doors and windows. Recently, high-density polyethylene for the manufacture of high-strength ultra-thin film, food, agricultural products and textile packaging materials developed rapidly.
3. Medium Density Polyethylene (MDPE) (1) Properties
Density 0.926 ~ 0.940g / cm3, the molecular structure for the number of branches between the high-density polyethylene and low-density ethylene linear polymer. The crystallinity of 70% to 75%, softening temperature of 110oC ~ 115oC, in addition to both high and low density polyethylene properties, but also has excellent resistance to stress cracking, rigidity and heat resistance. (2) use
The most suitable for high-speed blow molding manufacturing bottles, high-speed automatic parcel film and a variety of injection molding products and rotating molding products, such as barrels, cans and so on. Can also be used for wire and cable cladding.
4. Linear Low Density Polyethylene (LLDPE) (1) Performance
The linear low density polyethylene has a density of 0.910 to 0.925 g / cm3. As the molecular chain of linear low density polyethylene molecular chain short-chain, molecular structure between linear high-density polyethylene and long-chain branched low-density polyethylene between the high-pressure, so its physical and mechanical properties is better than ordinary low Density of polyethylene.
In the mechanical properties, linear low density polyethylene tensile strength than ordinary low density and ethylene 50% to 70%, elongation of more than 50%, impact resistance, puncture strength and low temperature impact performance than low Density of polyethylene is good. In the physical properties, the same density, the linear low-density polyethylene melting point higher than the low-density polyethylene, the use of a wide temperature range, allowing the use of low-density polyethylene than high temperature 10oC ~ 15oC.
Linear low-density polyethylene can replace low-density polyethylene film, pipe, injection molding products, hollow blow molding containers, rotating molding products and wire and cable coating materials. The mechanical properties of the obtained product are better than that of the low-density polyethylene.
