High-Density Polyethylene (HDPE):
It is frequently used as a plastic for milk cartons and other liquids, laundry detergent, garbage bins, piping for domestic water supply and agricultural process, fuel tanks for vehicles and etc. In the most cases usage of Linear Low-Density Polyethylene is similar with HDPE, and it seems that using two compounds in the condition of the surplus or deficit is possible.
Low-Density Polyethylene (LDPE & LLDPE):
LDPE is widely used in the production of lightweight plastic containers and plastic bags. LLDPE (Linear Low-Density Polyethylene) because of high flexibility is used in flexible plastic materials such as pipes, naylex and nylons for farming and shirinking.
Polyethylene Terephthalate (PET):
It is the most common thermoplastic polymer resin of the polyester family and is used in fibers for clothing, containers for liquids and foods, thermoforming for manufacturing, and in combination with glass fiber for engineering resins.
Polypropylene (PP):
It is also known as polypropene used in a wide variety of applications including packaging and labeling, stationery, plastic parts and reusable containers of various types, laboratory equipment, injection syringes, loudspeakers, automotive components such as batteries, interior trim and door design. It can also be used in production of packages for consumer products, including furniture and appliances, sports clothing, agricultural tools and textile industry.
Polyvinyl chloride (PVC):
PVC can be used as the following:
The most demand for PVC is for construction industry. Packaging for films, bottles and other materials. PVC sheets include awnings, windows, curtains, flooring materials, suitcases and etc. PVC also has the largest market in wire and cable.
Polystyrene (HIPS & GPPS):
The use of polystyrene products is in the building bricks, ceiling blocks industries, production of foam plastic, milk containers and sporting goods.
Urea:
About 90 percent of world production of urea is used in agriculture and it has the highest amount of Nitrogen among other solid nitrogenous fertilizers.
The urea’s most consumption is in the production of agricultural fertilizer, and after that producing animal nitrogen feed without protein. It is also used in the construction of urea formaldehyde resin systems and finally for preparing melamine.
