Plasticizers. Plasticizers ensure elasticity and flexibility of polymer materials. But this is not their only benefit. Plasticizers also optimize, for example, the processing properties of polymer materials, which leads to improved product quality or even new properties. The choice of plasticizers depends on the demand placed on the finished
Plasticizers: Types, Uses, Classification, Selection & Regulation
Polymeric Plasticizers Polymeric plasticizers (typically made from aliphatic dibasic acids such as adipic acid and diols) are valued primarily for their permanence. Many have low solvency for PVC and high viscosity, both of which can make processing f-PVC compounds difficult. Many have poor low temperature properties and may be sensitive to
Plasticizers: POLYSORB ID, plant-based solutions
BIOSUCCINIUM can be used in combination with industry-common alcohols to make DEHS di-(2-ethylhexyl)-succinate, or alternatively a biobased alcohol can be used in order to obtain 100% biobased plasticizers. When using suitable diols, BIOSUCCINIUM can also be used as a building block in linear or branched polymeric plasticizers.
- What is a plasticized polymer?
- Poly (vinyl chloride) is the most widely plasticized polymer. The properties of this resin in the plasticized state are greatly affected by the presence of a small amount of crystallinity, as shown by Reding et al. . For semicrystalline polymers, a plasticizer will depress the melting point and reduce the degree of crystallinity.
- Which polymeric plasticizers are used for PVC?
- Many of the data supplied by producers of polymeric plasticizers for PVC are on blends, which contain about 10% monomeric plasticizer. This is true for chlorinated polyethylene, butadiene–acrylonitrile copolymers, and the graft copolymer of polycaprolactone on polystyrene .
- What are plasticizers used for?
- Plasticizers are primarily used in the production of flexible PVC, accounting for around 90% of their applications. They have minor uses in rubber, adhesives, sealants, paints, lacquers, and lubricants. To obtain soft PVC, plasticizers must have the following essential performance properties: Plasticizers are used to make PVC more flexible.
- What is the molecular effect of a monomeric plasticizer?
- The fundamental molecular effect of a monomeric plasticizer is to interact on a molecular scale with the segments of the polymer to speed up the viscoelastic response of the polymer. A polymeric plasticizer produces exactly the same result and increases the molecular mobility of the polymer chains.
- Can a monomeric plasticizer be used to make PVC?
- The use of monomeric plasticizers has made possible the fabrication of PVC at reduced temperatures. The introduction of a new plasticizer is always approached with caution, lest this new aspect reintroduce unwanted chemical stability problems. The evaluation of such systems is conducted in a variety of ways.
- Why do PVC processors use polymeric plasticizers?
- At temperatures high enough to give good flow, PVC undergoes rapid decomposition. Consequently, monomeric plasticizers were eagerly adopted by PVC processors. When the user demanded greater permanence, however, the polymeric plasticizer did not provide as great an improvement in flow as the monomeric plasticizer.
