Polymer films are extensively applied in medical, agricultural, packaging, and industrial fields, where mechanical performance has a direct impact on functionality, reliability, and service life. Among the key mechanical properties, stiffness is particularly critical, as it influences resistance to deformation, handling characteristics, and structural stability during use. Film stiffness does not arise from a single parameter but from the interaction of multiple factors. Material composition, molecular structure, processing conditions, and environmental exposure collectively determine the final stiffness profile of a polymer film. A clear and systematic understanding of these influences is essential for engineers, product developers, and procurement professionals when

Injection molding is a process where molten material is injected into a mold to create a precise shape. While plastics are most common, metals and rubbers can also be used. Choosing the right material is critical, as it directly affects the product’s strength, flexibility, durability, and overall performance. Materials differ in melting points, shrink rates, and other properties, which can impact molding success. Learn more about selecting the best materials for injection molding by reading our full guide on TLD Vietnam’s blog. Considerations When Selecting Materials for Injection Molding Selecting the appropriate material for injection molding is crucial, and a

In plastic mold manufacturing, injection molding and extrusion are two common methods used in producing plastic products. There is a slight similarity between these two methods, which is why most people think they are the same. But they are not; they are way different. In this post, TLD Vietnam will share with you the differences between extrusion vs injection molding.  Extrusion vs Injection Molding: Trace back to the history Extrusion molding was invented in the early 19th century. It first started in 1820 when Thomas Hancock produced a rubber masticator that was designed to recycle processed rubber waste. And in

Acrylic Processing Aid, commonly referred to as ACR, plays an indispensable role in modern PVC processing, especially as manufacturers demand higher efficiency, improved melt behavior, and superior product performance. As PVC continues to dominate applications such as pipes, profiles, sheets, cables, and injection-molded parts, the use of ACR in PVC has become essential to ensure smooth processing, optimal gelation, and enhanced mechanical and surface properties. This comprehensive guide of TLD Vietnam explores the chemistry, technical functions, applications, and key specifications of ACR, providing manufacturers and industry professionals with a complete, in-depth understanding of this important additive and the expanding role
