Plasticizers: Types, Uses, Classification, Selection & Regulation
There are two main principal methods exist for plasticization - Internal Plasticization and External Plasticization. Internal Plasticization A polymer can be internally plasticized by chemically modifying the polymer or monomer so that the flexibility is increased.

For such service, the plasticizer and other ingredients must be electrical grades. Long-term wet electrical requirements necessitate close quality control of all materials. Plasticized PVC compounds can have ame resistance ranging from slow-burning, when ammable plasticizers are used, to self-extinguishing when compounded with

have been reported as suitable methods to monitor phase transitions and elastic moduli indicating molecular gelatin/plasticizer interac-tions and their effect on shell elasticity, i.e. to evaluate plasticizer effectivity and compatibility (Reich, 1983, 1994). An ideal plasticizer should interact with the gelatin molecules in such a way as to reduce

The PLA used in this work was a commercial grade Ingeo TM Biopolymer 6201D (MFI = 15–30 g/10 min at 210 °C) supplied by NatureWorks (Minnetonka, MN, USA). Its main properties are a density of 1.24 g cm 3 , a glass transition temperature in the 55–60 °C range, and a melt temperature range comprised between 155–170 °C.
- How are plasticizers classified?
- Plasticizers are classified based on their chemical composition. It is important to understand the influence of structural elements on the properties of plasticizers and their effect on base polymers. For example, the presence of elements like alcohols in a homologous series of phthalates, and adipates.
- What is a plasticizer chemistry?
- Plasticizers are the most used additives in the plastics industry. They are generally available as non-volatile, colorless liquids. They improve the properties of the polymer. With several plasticizer chemistries available in the market choosing the right one can be daunting. In this guide, you will read more about:
- 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.
- What are plasticizers & how do they work?
- Plasticizers are non-volatile organic substances (mainly liquids) added into a plastic or elastomer. They are also usually cheaper than other additives. They improve the following properties of the polymers: Plasticizers increase the flow and thermoplasticity of a polymer.
- What is a polymeric plasticizer?
- Polymeric plasticizers are typically made from aliphatic dibasic acids such as adipic acid and diols. They are primarily valued for their permanence. These plasticizers are generally classified as polyesters, not adipates. Many have low solvency for PVC and high viscosity. Both these factors can make processing f-PVC compounds difficult.
- Why are plasticizers used in polyvinyl chloride?
- Plasticizers increase the flow and thermoplasticity of a polymer. This is done by decreasing the viscosity of the polymer melt, Tg, Tm, and elastic modulus of the finished product. During this process, the fundamental chemical character of the plasticized material remains unaltered. Plasticizers are most often used in Polyvinyl chloride.
