Whatever we should know about low density polyethylene?
Low-density polyethylene – LDPE is terminologically composed of two terms monomer meaning single part and ethylene which is a hydrocarbon with the formula C 2 H 4. Lightweight polyethylene was produced in 1933 under very high pressure and along with the radical release of polymerization by the British company ICT. Also, the rate of degradability of this material in nature according to the EPA or environmental protection test is equal to 5.7%, which is determined by the degradability number 4. Despite the fact that many polymer products have been produced and industrialized in global markets, today LDPE is considered as one of the most important products in the plastic industry, so that in 2013, the revenue of this product in the markets around the world was about $ 33 billion. it is arrived . Properties of lightweight polyethylene – LDPE LDPE densities range from 0.91 to 0.940 g / m3.…
Density polyethylene and low density polyethylene
Polyethylene people know as (PE) , it is a thermoplastic polymer with a variable crystal structure that has the simplest molecular structure n (CH2-CH2–) among polymers and has a wide range of applications depending on its specific type. This plastic material was first produced in 1933 by Faust and Gibson in a laboratory, and today this type of plastic is widely produced and used in the world, ie about tens of millions of tons per year; Hence this exceptional polymer is widely used in plastic products around the world Types of polyethylene There are several types of polyethylenes, two of which are the most popular, one being low density polyethylene (LDPE) and the other being high density polyethylene (HDPE). The term density used to describe this type of plastic refers to the ways in which polymer molecules bond. In fact, the molecular structure is what makes all kinds of plastics with…
