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 Bonding In essence, plast

Both DOP (dioctyl phthalate) and DOTP (dioctyl terephthalate) primarily function to impart flexibility, toughness, and ease of processing to rigid plastics (especially polyvinyl chloride, PVC), but their key differences determine their different application focuses. DOP, as a general-purpose plasticizer, mainly serves to efficiently and economically lower the glass transition temperature of plastics, making them soft and pliable at room temperature. It is widely used in cost-sensitive traditiona

Plasticizer Leon on Instagram: "How to distinguish between main plasticizers and auxiliary plasticizers Based on the functions, compatibility and properties of the plasticizers, we classify them into main plasticizers and auxiliary plasticizers. 1. Purpose and Role Main Plasticizers: Primary function is to significantly enhance the flexibility, softness, and processability of the polymer. They are highly compatible with the polymer (e.g., PVC) and provide long-term plasticizing effects. They are

Plasticizer Leon on Instagram: "How DOP Improves the Flexibility of PVC Materials​ Polyvinyl chloride (PVC), due to the presence of a large number of chlorine atoms in its molecular chains, exhibits strong polarity and significant intermolecular forces. As a result, pure PVC is hard and brittle, which limits its applications. Dioctyl phthalate (DOP), a commonly used plasticizer, can effectively enhance its flexibility.​ DOP is an organic ester compound with large and flexible molecules, and its
