What is a Polymer?
A polymer is a large molecule, or macromolecule, composed of many repeated and long chain subunits. Human DNA is a polymer with over 20 billion constituent atoms. Proteins (made up of amino acids), anything plastic and many other molecules that make up life are polymers.
Polymer Types
There are two types of polymers that play an essential role in everyday life:
What is a thermoplastic?
A thermoplastic is a type of plastic made from polymer resin that becomes a homogenized liquid when heated and hard when cooled. Thermoplastic materials can be cooled and heated several times. Thermoplastics have wide ranging properties. Depending upon their chemistry they can be very much like rubber, or as strong as aluminum. There are various kinds of thermoplastics, with each type varying in crystalline organization and density that the most common products are including Polyethylene (PE), polypropylene (PP) and etc.
What is a Polyethylene (PE)?
Polyethylene is the most common plastic with annual consumption rates exceeding 50 billion pounds per year. Polyethylene is a polyolefin (high molecular weight hydrocarbons) that we use its most in our daily life including: grocery bags, shampoo bottles, children's toys, shopping bags , detergent bottles ,automobile fuel tanks and etc. PE is widely properties depend on the degree of branching of the chain. PE can be produced in two commercial types that are available:
1. Iran Petrochemical Co High Density Polyethylene (HDPE)
What is a HDPE?
High-density polyethylene (HDPE) is one of the most commonly used plastics in across the world. Iran HDPE is a polyethylene thermoplastic made from petroleum and its recycling code is 2. (#2 plastic Label)
Iran HDPE Special Features
Iran HDPE Uses
Iran HDPE is used to create sturdy products like PE pipe , blow-molded bottles for milk and household cleaners; blow-extruded grocery bags, construction film, and agricultural mulch; and injection-molded pails, caps, appliance housings, and toys. It is also typically found in milk jugs, plastic bags and refillable plastic bottles. In addition to plastic lumber and recycled plastic furniture, recycled HDPE is used to buckets, crates, office products and automobile parts.
2. Iran Petrochemical Co Linear Low Density Polyethylene (LLDPE)
What is a LLDPE?
Linear Low Density Polyethylene (LLDPE) is a linear polymer (polyethylene) that is a thermoplastic made from the copolymer of ethylene and another longer olefin. Iran LLDPE has a significant number of short branches so they can slide against each other upon elongation without becoming entangled .It is marked with the resin and its recycling code is 4. (#4)
Iran LLDPE Special Features
Iran LLDPE Uses
Principal uses are in packaging film, trash and grocery bags, agricultural mulch, wire and cable insulation, squeeze bottles, toys, housewares, high frequency insulation, chemical tank or canal linings, heavy duty sacks, potable water reservoirs, Floating Covers, storage tanks.
3. Iran Petrochemical Co Polypropylene (PP)
What is a PP?
Polypropylene (PP) is the second thermoplastic polymer used in a wide variety of applications such as packaging, labeling, textiles and also use it as a fiber-type plastic. Polypropylene is one type of plastic that is used for a number of different products, due to its wide variety of properties.
Iran PP Special Features
Iran PP Uses
Iran Petrochemical Co PP is versatile so its uses are numerous. They are including:
Plastic parts (from toys to automobile products), Carpeting, Recycled products, Paper, Technology, Laboratory equipment and etc.
Many things in the world are made of polymers so polymers have crucial and critical roles in our life. Anything plastic and many other molecules that make up life are polymers. Iran Polymer production is developing quickly because of the high demand of polymers in the most industries.
Some advantage of Iran Petrochemical co:
