Plastic has become one of the primary materials for household and industrial use products. Among the most widely used and versatile plastics is Polyethylene, a material that occupies a dominant share of the global plastics market. Its unique combination of chemical resistance, electrical insulation, flexibility, and cost-effectiveness has made it a preferred choice across industries. Read on blog of TLD Vietnam to explore the key properties and applications of Polyethylene. Definition And Fundamental Structure Of Polyethylene Polyethylene is a thermoplastic polymer with the chemical formula (C₂H₄)ₙ, where each repeating unit consists of two carbon atoms bonded to four hydrogen atoms.

In discussions of polypropylene and other polymer-based plastics, polymerization is the industrial chemical process in which monomers, small molecular units, chemically bond to create larger, more complex polymer structures. This article of TLD Vietnam examines this process within chemical processes, outlining its types, representative examples, and underlying mechanisms. What Is Polymerization? To fully understand the polymerization, you have to know the definition of a monomer first. A monomer is defined as a simple molecule with two or more binding sites. Then, the polymerization is a chemical process where multiple monomer molecules react to form a polymer, resulting in macromolecules with

PVC (polyvinyl chloride) pipes are widely used in many fields, and the demand continues to grow with the global market reaching 25.90 million tons in 2024. The production process of PVC pipes includes multiple steps such as raw material selection, plasticization, molding, cooling, etc., involving multiple fields such as chemistry, mechanics, and thermodynamics. This article, TLD Vietnam, will introduce the PVC pipe manufacturing process in detail. What Is PVC Material Made Of? PVC resin is synthesized from vinyl chloride monomers. The process starts with the production of vinyl chloride monomer (VCM) through the reaction of ethylene with chlorine in the

With several advantages over other manufacturing techniques, plastic injection molding has become one of the most popular methods employed by manufacturers worldwide. This process involves the use of plastic resins, and its versatility is one of its most attractive features. However, with so many types of plastic resins available in the market, choosing the right one for a project can be challenging. When selecting a resin for plastic injection molding, it is essential to keep in mind the project’s requirements. With this factor in focus, making the right choice becomes far easier.
