Synthesis and properties of a bio-based PVC plasticizer
The new plasticizer ALHD gave PVC products better toughness and strength; therefore, it can be used as either a primary or secondary plasticizer. Thermal stability and DSC analysis Thermal stability of the plasticizers and PVC specimens was researched using TGA and the obtained data are shown in Fig. 9 and Table 3 .
Plasticizers: Types, Uses, Classification, Selection & Regulation
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.
Plasticizer - an overview | ScienceDirect Topics
Plasticizers are used to convert PVC, a rigid plastic, into a soft, flexible, and elastic material. A plasticizer that is compatible with PVC and exhibits low volatility, good permanence, and high efficiency is referred to as a primary plasticizer. A secondary plasticizer has the opposite characteristics of a primary plasticizer.
- What are the different types of plasticizers?
- There are two main groups of plasticizers: primary—the main plasticizer in a PVC blend, added in large quantities and highly compatible with PVC; and secondary—having limited compatibility with PVC, easily migrating, especially when used in excess and usually added to the blend to improve its properties or to reduce its costs . Figure 1.
- What is PVC used for?
- PVC is usually applied in the production of cables, floorings, packaging, medical devices, toys, etc. [1, 2] Plasticizers are the most popular plastic additive that makes materials more flexible and easier to process, and about 90% of them are used for PVC applications. Traditionally, the most common PVC plasticizers are phthalates.
- What is the landscape of plasticizers for polyvinyl chloride (PVC)?
- The landscape of plasticizers for polyvinyl chloride (PVC) is evolving rapidly. As the awareness of environmental and health implications increases, innovation in this area becomes crucial.
- Which plasticizer molecule provides a beneficial interaction with the PVC chain?
- There exist numerous structures of plasticizer molecules that provide beneficial interactions with the PVC chain, like ester groups, epoxy groups, aromatic rings, hydroxyl groups, etc.
- What is the role of plasticizers in PVC?
- Understanding the role of plasticizers is crucial, as they significantly influence the properties and applications of PVC. They impact flexibility, durability, and processing efficiency. These characteristics make PVC a versatile material used across numerous industries, from construction to healthcare.
