LLDPE granules
Linear Low Density Polyethylene (LLDPE) is a copolymer of ethylene and a small amount of advanced olefin in the presence of catalyst. LLDPE is similar to LDPE in appearance, with poor transparency and good surface gloss. LLDPE has the advantages of low temperature toughness, high modulus, bending resistance and stress cracking resistance, and good impact strength at low temperature.
Widely used in industry, agriculture, medicine, hygiene and daily necessities and other fields. Suitable for film, molding, tubing
and wire and cable. A new application is as a mulch film for landfills and linings for waste pools.
Properties:
Easy weldability & machine ability
Good thermoforming
High Corrosion Resistance
low moisture absorption
Good abrasion resistance
Electrical insulating properties
High Strength
High percentage elongation at break
Usable at temp. of -50°C to + 85°C
No water absorption
1. Heat sealing LLDPE film has good heat sealing property, as long as the lowest sealing temperature is reached, it has good heat sealing strength and strong sealing resistance to pollution.
2. Melting performance The melting performance depends on the relative molecular mass, relative molecular mass distribution, long branch chain and other factors. Similarly, the relationship between melt flow rate LLDPE and LDPE and shear rate :LLDPE behavior is similar to HDPE with narrow molecular mass distribution, and the melt viscosity is higher than LDPE, so the extrusion load increases and the heat increase during extrusion molding. The melting tension of LLDPE is lower than that of LDPE, and the relaxation time of melting stress is shorter. It can be observed that the melt film extruded from the "T" head has a large shrinking neck, and the vertical elongation of the billet during hollow molding is large. Because the melting stress relaxation time is short, the residual stress in the injection molding product is small, so the shrinkage rate is small, and the warpage is small.
3. Thermal performance The melting point of polyethylene is proportional to the complete degree of crystallization and grain size, so the melting point of LLDPE is 10-15 degrees Celsius higher than LDPE, even if the same LLDPE, the more carbon of the copolymer monomer, the higher the melting point. The same rule applies to Vicar softening point. The thermal sealing performance of the film corresponds to the heat sealing temperature of the fully melted, and the thermal sealing temperature of LLDPE is 10-15 degrees Celsius higher than that of LDPE, and the melting point range of LLDPE is narrower than LDPE, so the thermal sealing performance of the film is good. The cold resistance of LLDPE, in terms of the relationship between catalytic temperature and melt flow rate, the embrittlement temperature of LLDPE is lower than that of LDPE and HDPE, which indicates that it can withstand lower temperatures.
4. Physical and mechanical properties The ratio of LLDPE tensile properties to LDPE properties, tensile quantity and tensile yield strength are large, especially tensile fracture strength and elongation at break. Generally, the energy required at fracture can be obtained from the area of the stress-strain curve, which is used as an indicator of resin rigidity. Obviously, the rigidity of LLDPE is good, which can be thought to be due to the number of chain molecules in LLDPE molecules. The relation between rigidity and density: the lower the density, the worse the rigidity (i.e., the softer). In terms of the same density, LLDPE has a higher impact strength, and the impact strength of C6 and C8 copolymers more than C4 is higher. The physical and mechanical properties of LLDPE film are obviously better than LDPE, and its softness, toughness, cold resistance and puncture resistance are better than LDPE.
