ldpe granules petrochemicals suppliers in Tehran
Lightweight polyethylene (ldpe granules petrochemicals ) is commonly used in the production of various types of plastic materials. Polyethylenes of 209 and 020 are from this category of materials. That produce nylon-niloxes-the production of small-sized polyethylene pipes-the production of a type bar for drip irrigation-the production of various types of polyethylene and more. used.
A family of thermoplastics obtain by polymerization of ethylene gas (C2H4). Low molecular weight polymers use as lubricants. The polymers of the average molecular weight of the waxes fuse with paraffin. And also finally, polymers with a molecular weight greater than 6000 in the plastic industry account for the largest volume of consumption. Polyethylene contains a very simple structure, which is simpler than all commercial polymers.
Sometimes instead of hydrogen atoms in the molecule (PE). A long chain of ethylene to carbon atoms attache to them, polyethylene branch or low-density polyethylene (LDPE) say. Because its density due to occupy more volume, was reduced. In this type of polyethylene, the molecules of ethylene also are randomly attached to each other and poured into a very irregular shape.
Lightweight polyethylene (low density) is generally a softer polythene and has a lower crystallinity. This polymer usually present as globulin and is widely used in applications where transparency, neutrality, ease of processability, durability and good electrical properties are considered.
Polyethylene Style 209
The grade of this product is about 0.9 and the packaging is 209 polyethylene bags in 25kg bags.
020 is also a subsidiary of the production of various types of nylon-made nylon-made plastic nylon containers and extra. The polyethylene is lightweight 020 and the degree of rhinestone of this product is about 2.3 and its packing is in 25 kg bags.
Polythene also is a film of polymer material in the group of thermoplastics. It uses for producing polyethylene pipes, making small containers, making household dishes, toys, wrapping electrical and telecommunication cables, films, various parts of cars, appliances Sports and labs and industrial parts.
Polyethylene film style ldpe granules petrochemicals
Polyethylene low density (ldpe granules petrochemicals ) also is a polymer material and in the group of thermoplastics. Film style polyethylene has a branched chain.
LDPE chains can not bond well, with less intermolecular force and tensile strength.
It use to produce polyethylene pipes, to make small volume containers. To make household utensils, toys, electrical and telecommunication cables, films, various car parts, sports equipment and labs, and industrial parts.
Film style polyethylene also is usually stable, it needs to preheat for fire, almost no protection.
This polyethylene has branched chains, so LDPE chains can not bond well, with less intermolecular force and tensile strength. This type of polyethylene usually produce by radical polymerization.
The properties of this polymer are flexible and decompos by microorganisms. Polyethylene in terms of compactness, low and low-molecular low density is the same, increase its flexibility. This property makes more than fifty percent of production in film and sheet for use in coatings talcous transparent, Inserts closed Covers, covers and luggage. This kind of polymer also use to make plates like pressure bottles.
Other uses include lightweight polyethylene, insulating wires and cables, and paper overlays. Polyethylene was first synthesized accidentally by a German chemist.
Material for producing polyethylene pipes, making small containers, making household utensils, toys, electrical and telecommunication wires, films, various car parts, sporting and laboratory equipment and industrial parts
Physical and chemical properties:
Density range: 0 910 -0.940, inactive at room temperature, between 80-95, is stable for a short time.
