Why is a plasticizer added to the PLA? 1. Reducing Brittleness Why: Pure PLA has a high glass transition temperature (Tg) of around 5560°C and low elongation at break (typically 210%). This makes it prone to cracking or shattering under stress, especially in thin films or molded parts. How Plasticizers Help: They lower the Tg by increasing molecular mobility within the polymer chains, making PLA less stiff and more deformable without breaking. For example, adding 1020% of a plasticizer like glyc

DOP DOTP CPW Flash Point and Ignition Point of Plasticizers Is a higher flash point always better for plasticizers? This statement is inaccurate. The flash point of a plasticizer needs to be selected based on the application scenario. Some customers prefer a high flash point for better temperature resistance, while others prefer a lower flash point for better acceleration. The quality of the plasticizer is not affected by its flash point. Plasticizers vaporize during heating. For a substance to

Plastificante Alice on Instagram: "Do Plasticizers Have Heating Weight Loss?​ ​Ever wondered if plasticizers experience heating weight loss? The answer is yes!​ Heating weight loss in plasticizers occurs when volatile components evaporate upon heating. Since plasticizers are often blends of organic compounds, some of their parts can easily vaporize. When heated, these volatile substances escape, reducing the plasticizer's overall weight.​ The extent of heating weight loss varies. It depends on t

Leo Lai on Instagram: "What is the mechanism of plasticizers? Plasticizers are additives that enhance the flexibility, workability, and extensibility of polymers, typically rigid ones like polyvinyl chloride (PVC). Their mechanism involves altering the physical properties of the polymer at a molecular level without chemically reacting with it. 1. Insertion Between Polymer Chains 2. Reduction of Intermolecular Forces 3. Increased Chain Mobility 4. Solvation and Shielding Effects 5. No Chemical Bo
