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.
Polymeric Plasticizers
Polymeric Plasticizers Polymer plasticizers or polyadipates are polyesters of aliphatic dicarboxylic acids. BASF manufactures and markets the following polymer plasticizers for special applications:

BASF also produces specialty plasticizers, such as linear phthalates, trimellitates, such as Palatinol TOTM, adipates, and polymeric plasticizers in order to meet customer requirements, such as high or low temperature performance and low migration.

High ACN polymers require high polarity plasticizers, low ACN polymers require low polarity plasticizers. Polymerics used at greater than 15 PPHR are generally used in combinations with monomerics. Hallstar has a wide range of monomeric and polymeric plasticizers that can be used with NBR. APPLICATIONS

- 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.
- 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.
- What is the permanence of high molecular weight plasticizers?
- The permanence of high molecular weight plasticizers is such that the average molecular weight of the polymeric plasticizer is no longer a factor.
- Are plasticizers suitable for elastomers and high-temperature polymers?
- Plasticizers commonly used for the traditional and the high-temperature polymers are extractable, incompatible or too volatile. This paper provides information on plasticizers that are designed for traditional elastomers and high-performance polymers.
- Why are polymeric plasticizers used in PVC?
- The use of polymeric plasticizers in PVC is not characteristic in one sense. PVC is a very viscous polymer and is difficult to process in commercial equipment. At temperatures high enough to give good flow, PVC undergoes rapid decomposition. Consequently, monomeric plasticizers were eagerly adopted by PVC processors.
- Which plasticizer is better – low or high molecular weight?
- Poly (vinyl chloride), plasticized with low, medium, and high molecular weight plasticizers, is an excellent example of such behavior. Low molecular weight plasticizers are more efficient but suffer from impermanence. High molecular weight plasticizers have superior permanence and better physical and electrical properties, but are less efficient.
