Polymeric Plasticizers
Polymer plasticizers or polyadipates are polyesters of aliphatic dicarboxylic acids. BASF manufactures and markets the following polymer plasticizers for special applications: Palamoll products (polyesters of aliphatic dicarboxylic acids) Palamoll 632: Technical Information Palamoll 638: Technical Information
Eastman Plasticizers for PVC
Benzoflex - 181 Plasticizer Benzoflex181 is a water white alkyl benzoate ester with low odor, low viscosity and excellent compatibility with PVC. Benzoflex181’s principal use is as a low viscosity plasticizer for plastisol applications. Benzoflex 181 may also be used in other applications requiring a low viscosity, high solvating plasticizer.

- Why do we need plasticizers in polyvinyl chloride (PVC)?
- Plasticizers play a crucial role in the overall performance and usability of polyvinyl chloride (PVC). Their addition can significantly alter the mechanical properties of PVC, thereby expanding its application range.
- How can plasticizers be used to make polymers soft and flexible?
- 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. Plasticizers are classified according to their molecular structure into monomeric or polymeric types.
- How do plasticizers affect the performance of PVC products?
- Plasticizers influence the flexibility, workability, and durability of PVC products. Choosing the right type of plasticizer can enhance the performance characteristics of PVC while also addressing environmental and health concerns.
- What makes a good plasticizer?
- A good plasticizer must blend uniformly with the PVC matrix, ensuring that it does not phase-separate or lead to inconsistency in the material properties. An effective means to evaluate compatibility is through the analysis of: Solubility: The plasticizer should dissolve in PVC without forming precipitates.
- Are PVC resins compatible with plasticizers?
- Compatibility between plasticizers and PVC resins is another fundamental aspect that determines the overall performance of the final product. A good plasticizer must blend uniformly with the PVC matrix, ensuring that it does not phase-separate or lead to inconsistency in the material properties.
- Are phthalate plasticizers good for PVC?
- Phthalate plasticizers have been the conventional choice in the PVC industry for many years. They improve the flexibility and processability of PVC, making it suitable for a wide range of applications, such as pipes, vinyl flooring, and medical devices.
