Secondary Plasticizers | Galata chemicals
Focusing our efforts on delivering greener and more sustainable solutions, the DRAPEX plasticizers are manufactured from renewable feedstock and effectively serve as both secondary plasticizers and co-stabilizers in nearly all PVC systems. Epoxidized plasticizers impart good weathering stability and can also act as an internal lubricant or
Plasticizers: Types, Uses, Classification, Selection & Regulation
Secondary plasticizers may have limited compatibility with the polymer and/or high volatility. They may or may not contain functional groups which allow them to solvate the polymer at processing temperatures. Secondary plasticizers are variously used for: Cost reduction Viscosity reduction Solvency enhancement Surface lubricity augmentation, and

DINP plasticizer. Jayflex DINP plasticizer is the largest-volume and preferred general-purpose high-molecular-weight plasticizer for PVC, providing the opportunity for cost savings with a good balance of properties.
Classification of plasticizers - Oxoplast
Secondary plasticizers contain groups which are less polar. They demonstrate limited solubility and compatibility with PVC, that is why they are often used in mixtures with primary plasticizers. Such mixtures show a reduced tendency to migration, but increased strength at reduced temperatures and resistance to precipitation.
- What is a primary plasticizer?
- A primary plasticizer enhances elongation, softness and flexibility of polymer. They are highly compatible with polymers and can be added in large quantities. For example: up to 50% of vinyl gloves are made up of plasticizers, which make the PVC flexible and soft enough to wear.
- What makes a polymer a good plasticizer?
- It is nowadays established that good plasticization implies secondary bonds, also known as intermolecular forces, with the polymer. The attraction between plasticizer molecules and the polymer must be as strong as the interactions between molecules in the single components to generate an efficient polymer-plasticizer interaction.
- What are secondary plasticizers?
- Secondary plasticizers are additives which, when combined with the primary plasticizers, can improve the properties of the final material . In the present work, a glycerol derivative (triacetin—TAG) was used as PVC secondary plasticizer.
- How do plasticizers affect polymers?
- Plasticizers are substances which, by virtue of their polar or polarizable structure, weaken the secondary valence forces of polymers. By adding plasticizers to compatible polymers, the materials can be modified in such a way that they become soft and flexible by decreasing their glass transition temperature.
- Which plasticizer has a good plasticizing efficiency?
- Both plasticizers provided a satisfactory plasticizing efficiency, such as DEP, due to their low viscosity and ease of diffusion into CA, which enables a large processing window and increases the material's flexibility. CA with 30 wt% GTA displayed a slightly higher elastic modulus than CA with 30 wt% GDA (E = 2.1 GPa and 1.9 GPa, respectively).
- What are plasticizers used for?
- Plasticizers are an important class of low molecular weight non-volatile compounds that are widely used in polymer industries as additives . The primary role of such substances is to improve the flexibility and processability of polymers by lowering the second order transition temperature, the glass transition temperature (Tg).
