Plastic is one of the synthetic materials that you frequently encounter in housewares, such as food containers, baskets, trash bags, and many more.  Not only that, but plastic is also used to produce automotive components, food packages, medical tools, and so on.  But, did you know what plastic is made of? This article of TLD Vietnam discusses the plastic raw materials and the manufacturing process. So, read the information until the end! Historical Background The origins of plastic trace back to the 19th century, when early synthetic materials were developed as substitutes for natural resources like ivory, shellac, or horn.

Naphtha is a volatile hydrocarbon mixture distilled from crude oil and widely used as a feedstock in refining and petrochemical production. Despite its simple appearance, naphtha plays a critical role in producing plastics, fuels, solvents, and other industrial materials essential to modern manufacturing. It forms the base for key chemicals like ethylene, propylene, and aromatics that drive the global polymer and chemical industries. To explore its properties, applications, and refining processes in detail, read the full analysis by TLD Vietnam below. What Is Naphtha? Naphtha is a liquid hydrocarbon mixture derived from crude oil processing, classified as an organic compound

Derived from stearic acid, calcium stearate and zinc stearate are essential for molding and good finishes in products like plastics, rubber, and cosmetics. Despite their similar appearances, each plays a distinct role in different applications. Choosing the wrong one can lead to poor surface quality, reduced cycle times, or regulatory challenges. In this guide, TLD Vietnam explains the key differences between Calcium Stearate vs Zinc Stearate to help manufacturers make informed decisions. Calcium Stearate vs Zinc Stearate: Basic Chemical Overview  Both calcium stearate and zinc stearate are metallic salts derived from stearic acid, a saturated fatty acid commonly obtained from

PVC’s thermal sensitivity, high melt viscosity, and tendency to stick to processing equipment necessitate specialized solutions for smooth and efficient processing. Lubricants play a vital role in addressing these challenges, improving both the performance and quality of PVC products. We have consistently highlighted the importance of lubricants in PVC applications. However, with numerous lubricant options available, PVC manufacturers may find the selection process complex. Choosing the right lubricant requires careful evaluation beyond personal preference to ensure optimal performance and efficiency.  In this blog, our goal is to guide PVC manufacturers through the key considerations for selecting the most suitable lubricant
