Plasticizers: Types, Uses, Classification, Selection & Regulation
Bio-based Plasticizers – They are based on epoxidized soybean oil (ESBO), epoxidized linseed oil (ELO), castor oil, palm oil, other vegetable oils, starches, sugars etc. Others – Includes Phosphates, Chlorinated Paraffins, Alkyl Sulfonic Acid Esters and more When added to polymer, these plasticizers provide several benefits as listed below.
Plasticiser loss from plastic or rubber products through diffusion and
Polymers experience degradation during storage and service. One of the main degradation mechanisms of plasticised-polymer products is the loss of plasticiser, which leads to poorer mechanical
Plastic Additives: Polymer Stabilizers, Plasticizers and
During the manufacturing of polymeric materials, such as plastics and rubbers, a number of chemical additives are added to inhibit or retard their degradation or to achieve better product quality. Heat stabilizers, antioxidant, UV absorber, plasticizers and lubricants are the most commonly seen and widely used additives.
Mesamoll | The universal plasticizer | LANXESS
Some plasticizers develop a high potential regarding scope of use, but they are designed for a specific use. Unimoll AGF, our largely bio based plasticizer, was developed for the use in articles intended to come into contact with foodstuffs. Our Uniplex Benzoates are mainly solid special plasticizers used in hot-melt adhesive & equipment
Plasticizer
For example, plasticizers are commonly added to polyvinyl chloride (PVC), which otherwise is hard and brittle, to make it soft and pliable; which makes it suitable for products such as shower curtains, vinyl flooring, clothing, bags, flexible plastic tubing, and electric wire insulation/coating.
- 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 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:
- Why do plasticizers reduce TG?
- The reduction of Tg is proportional to the temperature difference between the Tg of the polymer and plasticizer. Plasticization improves the flexibility and processability of polymers. Certain factors can counteract or restrict this enhancement. Certain polymers may have limited compatibility with specific plasticizers, hindering their integration.
- What is plasticization in chemistry?
- The term plasticization refers to the softening and increase in flexibility of a polymer. This change is due to the addition of specific additives, especially plasticizers. A plasticizer is a non-volatile substance incorporated in a plastic or elastomer. It changes the thermal and mechanical properties of the material.
- How do plasticizers affect a polymer?
- Well-chosen plasticizers can also improve resistance to UV exposure and chemical attack. This contributes to the long-term stability of the polymer. In specific applications, plasticizers can influence the dielectric properties of polymers.
- 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.
