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

What is solvent-based plasticizer?(Part 2) Examples of Solvent-Based Plasticizers Phthalates: Diethyl phthalate (DEP), dibutyl phthalate (DBP), di(2-ethylhexyl) phthalate (DEHP). Citrates: Acetyl tributyl citrate (ATBC), often used in food-grade or medical applications. Adipates: Dioctyl adipate (DOA), used for low-temperature flexibility. Phosphates: Tricresyl phosphate (TCP), used for flame-retardant properties. Applications Flexible PVC Products: Used in films, cables, flooring, and medical t
