Ionic liquids: New generation stable plasticizers for poly(vinyl
Fig. 1. Structures of ILs and traditional plasticizers. The effectiveness of these ILs and traditional plasticizers were studied in terms of flexibility, mechanical properties, and high temperature and UV stability they impart to PVC as plasticizers. The leaching and migration tendencies of these plasticizers were also investigated.
Current Status of Plasticizer Research | SpringerLink
Compared with phthalate esters, hexahydrophthalate esters have lower densities and viscosities for use as plasticizers, which can improve the low-temperature softness of plastics, while other properties such as Shore hardness and mechanical strength.
Plasticizers: Types, Uses, Classification, Selection & Regulation
The most widely used internal plasticizer monomers are: Vinyl acetate Vinylidene chloride But this technique is limited: every copolymer is only suited to certain flexibility requirements Also, the complexity of the reaction can lead to longer reaction times and increased costs.
Selection of Plasticizers for Coating Formulations
Good stability to heat and ultraviolet light Broad range of compatibility, and Excellent resistance to hydrolysis Di-iso-octyl phthalate (DIOP) DIOP is like DOP, an all-purpose plasticizer for polyvinyl chloride, polyvinyl acetate, rubbers, cellulose plastics, and polyurethane. Di-iso-nonyl phthalate (DINP) & Di-iso-decyl phthalate (DIDP)
Selecting Heat Stabilizers for PVC
Epoxy plasticizers (epoxidized soybean, linseed oils and tallate esters) are often used in PVC compounds as an auxillary co-stabilizer with mixed metal stabilizer systems. Functioning as HCl acceptors primarily, epoxy Plasticizers enhance the heat and light stability of most mixed metal/phosphite stabilized compounds.
- How to choose a plasticizer?
- The choice of the plasticizer is dependent on the requirements that have to be met for the final product and the conditions around that product’s use. This may include low volatility, high permanence, low temperature flexibility, flame retardancy, high thermal stability and saponification resistance.
- Which plasticizer is most stable after 10 d?
- After 10 d, the migration trend of all samples had been stabled, it showed that the traditional plasticizer like DOP, DOTP and DOA had basically move out from the PVC matrix in non-polar environment due to their own single structure, while the PVC plasticized with A-ODL showed the best stability in all the environment.
- 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.
- Why should you use epoxy plasticizers?
- Improved Thermal Stability: Epoxy plasticizers offer excellent resistance to heat, which is critical for high-temperature applications. High Compatibility: They are well-suited for use in conjunction with other plasticizers to optimize performance.
- Are plasticizers a good choice for PVC?
- According to the statistics, the total output of PVC in the world was over 49.0 million tons in 2019 . However, as a rigid polymer, pure PVC have certain drawbacks without any additives . Therefore, plasticizers are generally blended to improve the mechanical properties and thermal stability of PVC materials , .
- Why is a plasticizer important?
- The primary function of a plasticizer is to reduce the intermolecular forces between polymer chains, allowing them to move more freely, which in turn increases the material's flexibility, softness, and workability. Plasticizers are essential in manufacturing processes like extrusion, molding, and film formation.
