Plastic is made even without the use of milky white sap
Plastic can be produced from nature Today, plastic is made even without the use of rubber tree gum. Oil has replaced the viscous sap of the tree. The advantage of oil over latex is that it is cheaper. Despite advances in the production of plastics from synthetic materials, rubber can still not be completely abandoned. For example, if car tires are made only of synthetic plastic, they heat up very quickly, which is why about 50% of rubber is used in each tire ring. From its raw materials, after performing interactions, various types of tires are made, which are mainly used in tire manufacturing, shoe making, all vehicles, buildings and other industries. Rubber is one of the most essential materials in modern life. Due to its extraordinary elastic properties, rubber is used to make a variety of products, including hospital supplies, home appliances and toys. There is a growing interest…
What is global trade?
Global trade The simplest definition is international trade, which means the process of trading goods and products between two or more foreign markets. International trade allows countries to expand their markets and gain access to goods and services that might never be available in that country without international trade. As a result of international trade, markets become more competitive, which ultimately leads to more competitive pricing and cheaper goods for the consumer. International trade and foreign trade have been a fundamental factor in the emergence of the global economy. In international trade, supply and demand, and ultimately prices, are affected by global events, as a result of which global economic variables are defined and examined globally. For example, political change in Asia could lead to higher labor costs. This can increase the cost of producing an agricultural product, and increase the price of a product that a European consumer may…
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.…
