Polyvinyl chloride (PVC) ranks among the most commonly used plastics worldwide due to its adaptability, strength, and affordability. To improve its characteristics and make processing easier, manufacturers add different types of additives. One of the key additives used is calcium stearate, which serves several important functions in PVC production. This article of TLD Vietnam explores the benefits of Calcium stearate in PVC processing. Introduction To Calcium Stearate in PVC Processing Polyvinyl chloride (PVC) is among the most extensively used plastics worldwide, commonly applied in industries like construction, packaging, and healthcare. To produce high-quality PVC products, the use of additives such

Stone Plastic Composite (SPC) flooring is a highly sought-after flooring option, valued for its durability, water resistance, and low maintenance. A key component in its production is Calcium carbonate (CaCO₃), which significantly enhances the flooring’s performance, cost-effectiveness, and quality. In this article, TLD Vietnam outlines the process of incorporating Calcium carbonate in SPC flooring manufacturing, explaining its role, advantages, and the detailed steps involved. What Is Calcium Carbonate? Calcium carbonate is a naturally occurring mineral found in limestone, marble, and chalk. Its versatility and affordability make it a staple in industries like construction, plastics, rubber, paint, coatings and more. In

Stone Polymer Composite (SPC) has gained popularity in the building industry for SPC flooring, SPC wall panels, and other applications. Known for its durability, cost-effectiveness, and sustainable properties, SPC is a versatile option that appeals to a wide range of industries. This guide of TLD Vietnam covers SPC’s composition, applications, benefits, and why it’s a preferred option for flooring. What is SPC?  SPC, or Stone Polymer Composite, is a rigid core material made from Calcium carbonate powder, Polyvinyl chloride (PVC), and Ca-Zn stabilizers. This blend creates a robust, water-resistant, and scratch-resistant product ideal for residential and commercial spaces. Thanks to

Polyvinyl chloride (PVC) requires specific additives to prevent degradation during high-temperature and shear-intensive processing. Among these, PVC lubricants play a critical role in ensuring smooth processing of rigid PVC by influencing flow behavior and viscosity within processing equipment. Below, TLD Vietnam explores some aspects of internal and external lubricants for PVC applications and their impact on processing efficiency. The Role of PVC Lubricants PVC lubricants serve to minimize friction within the polymer matrix before melting and reduce friction between the PVC melt and the machinery’s contact surfaces. This facilitates smoother processing, enhances material flow, and prevents issues such as sticking
