WHAT IS LLDPE VIRGIN PLASTIC PELLETS?

LLDPE virgin plastic pellets are a line of virgin plastic beads that possess many outstanding features. Therefore, it has been and is being widely applied in many different areas of life. Although very popular, not everyone knows about this line of high-quality virgin plastic beads.

Outstanding features of LLDPE
► LLDPE resin is a molecular organic compound with the simplest structure. It is the most widely used molecular material in the world up to the present time. LLDPE virgin plastic is made up of Ethylene polymerization reaction, depending on the different density it will be divided into high, medium or low density LLDPE
► For low density slightly soft, most undergo high pressure polymerization. High density LLDPE usually has better stiffness, hardness and mechanical strength. In contrast to low density, high density LLDPE will undergo low polymerization.
► Therefore, high density is often used as a container, pipeline. LLDPE is even used as a high-frequency insulator. Used in radars and televisions. However, on the market today low density LLDPE is more commonly used. Besides, LLDPE in wax form gives a smooth waxy feel, when not stained with transparent low density LLDPE. In contrast, LLDPE at high density is not transparent.
► In addition, LLDPE is insoluble in water, with poor water absorption. Especially for some solvents such as Toluene, Acetic Acid.. when the temperature is above 70 degrees Celsius, it will dissolve a little. However, when in the form of small particles, the temperature fluctuates between 150 and 400 degrees Celsius. It depends on the change of temperature.
► It can melt or condense. In simple words, when the temperature is high, it will melt and absorb heat, and when the temperature is reduced, it will condense and release heat. Thanks to very little water absorption, not easy to moisture, along with good insulation, it becomes an extremely good building material.

The simplest way to distinguish LLDPE, HDPE and LDPE
Do you know? The fastest and most accurate way to distinguish between LLDPE and HDPE, LDPE primary plastic resins is based on density. Because by looking at the density you can tell the mechanical properties, one is hard, the other is flexible. LLDPE primary plastic differs from HDPE and LDPE primary plastic resins in molecular structure. LLDPE has more branched bananas so it is both soft and hard.

Distinguish by advantages
Primary LLDPE plastic beads are resistant to alkaline acids and organic solvents. Accompanied by good electrical insulation ability, when at low temperature, it still retains certain plasticity. Besides, the mechanical strength of this plastic material such as: Surface hardness, tensile strength, stiffness.. All are much higher than LDPE, but it is lower than HDPE. In terms of puncture strength, LLDPE is the best. Along with that is the ability to withstand cracking. Therefore it is the most excellent material for the production of thin films, even thinner than those made from virgin LDPE resin but with high strength.

Identify LLDPE virgin plastic beads through disadvantages
Due to the poor mechanical properties, the ventilation is also poor. In addition, it is aging, easy to deform, brittle, even less brittle than PP plastic beads. So it is easy to crack due to stress. In addition, their surface hardness is low, which is easy to scratch. In addition, it is very difficult to print, when printing needs to release electricity on the surface, can not be plated, the surface is not smooth. Therefore, it does not bring high aesthetics to finished plastic products.

What is LLDPE virgin plastic used for?
Thanks to its outstanding characteristics, this line of virgin plastic beads is popularly used in:
► Laminating packaging film, tape, cable, finished film, also known as paper imitation film.
► Plastic injection to make low-quality outer shell items.
► As a material that can be used in blow molding of plastic containers. Or empty products, bottles...
