Plasticizers: Types, Uses, Classification, Selection & Regulation
Plasticizers are among the most widely used additives in the plastic industry. They are also usually cheaper than other additives used in polymer processing. Plasticizers are most often used in PVC, the third largest polymer by volume after PP and PE. In turn, PVC is used in a wide range of products. Examples include:
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
Plasticizer - an overview | ScienceDirect Topics
Plasticizers are low molecular weight substances added to a polymer solution to promote its plasticity and flexibility. Therefore, the plasticizers make the polymer solution more suitable for the application of film coating. There should be chemical similarities between the polymers and its plasticizers.
One-pot and industrial manufacturing of cardanol-based polyoxyethylene
Plasticizer is essentially involved in improving the processability and flexibility of poly (vinyl chloride) (PVC) which has been applied in various fields, particularly in biomedical, automobile manufacturing, baby-care, and military (Li et al., 2018).
Using Polymer Plasticizers
Based on the type of application, other polymers utilize plasticizers in many different quantities. Paper contains about 5% of plasticizers, thermoplastic materials up to 10%, and elastomers at times as much as 60%; certain plastics also have 95% of plasticizers. How Plasticizers Work
- How can plasticizers be used in industrial applications?
- External plasticization using low molecular weight plasticizers is the most widely applied approach in industrial applications. The glass transition temperatures and the mechanical properties (elastic modulus) of CA systems with different plasticizer contents are reported in Table 2.
- Why do elastomer and plastic polymers need a plasticizer?
- Elastomer and plastic polymers may be tough, dry or rigid materials that, for many applications, have a need for plasticizers. A plasticizer, among other contributions, will reduce the melt viscosity, lower the temperature of a second order glass transition (Tg) or lower the elastic modulus of a polymer.
- What does a plasticizer do?
- A plasticizer, among other contributions, will reduce the melt viscosity, lower the temperature of a second order glass transition (Tg) or lower the elastic modulus of a polymer. This paper discusses ester plasticizers, one of the more common and important plasticizer classes.
- Are biopolymers a good substitute for conventional plasticizers?
- The use of natural and/or biodegradable plasticizers, with low toxicity and good compatibility with several plastics, resins, rubber and elastomers in substitution of conventional plasticizers, such as phthalates and other synthetic conventional plasticizers attracted the market along with the increasing worldwide trend towards use of biopolymers.
- What are polymeric plasticizers used for?
- Polymeric plasticizers offer low volatility, resistance to extraction from elastomer compounds by hydrocarbon fluids and, dependent upon choice of product, resistance to surface marring of ABS and polystyrene plastics. Thus, polymeric polyesters are used in a broad variety of rubber industry applications requiring plasticizer permanence.
- 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.
