Plasticizers: Types, Uses, Classification, Selection & Regulation
There are two main groups of external plasticizers: 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.
BASF Plasticizers Asia Pacific
Its large range of food contact and toy approvals as well as its outstanding technical properties and excellent toxicological profile have made Hexamoll DINCH a favourite of leading brands and the market leading plasticizer for branded toys in Asia. In March 2012, BASF launched the exclusive “Hexamoll DINCH Trusted Partners” program
Natural-based plasticizers and biopolymer films: A review
the amount of plasticizer strongly affect the lm formation from polymeric aqueous dispersions [26]. Hydrophilic plasticizers dissolve in the aqueous medium when they are added to polymer dispersions and if added in high con-centrationthey can lead to an increase inwater diffusion in the polymer. In contrast, hydrophobic plasticizers may

Blended with appropriate solvents, plasticizers, and other modifying resins, it is used in coatings formulations for a variety of substrates. This multipurpose rheology enhancer provides high strength and good resistance to ultraviolet light, heat, oils and greases. It is useful in lacquers for glass, plastic, wire and release coatings.
Influence of Plasticizers Basing on Renewable Sources on the
For all SBR–plasticizer combinations, the resistance against the initiation and propagation of an unstable crack becomes higher or remains constant with a plasticizer content of 12.5 phr (Fig. 7a). The further increase in plasticizer content leads to relatively strong decrease in J d, with exception of EECO.
- What are natural product type plasticizers?
- Vegetable oil derivatives are the most widely used natural product type plasticizers. Products consisting of triglyceride esters of unsaturated fatty acids (e.g., soybean oil, linseed oil) in which the double bonds in the fatty acid residues have typically been epoxidized have been commercial products for decades.
- 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.
- 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.
- How to choose a general-purpose plasticizer for PVC?
- While selecting a general-purpose plasticizer for PVC, the main attributes to be checked are: Among them, regulation is an important decision factor while selecting plasticizers. In recent years, there has been a lot of discussion on phthalate plasticizers. But in fact, not all phthalates are prohibited.
- Why is plasticization important?
- Plasticization is the process of making the final plastic product more flexible. By incorporating the right type and amount of plasticizer you can tweak your formulation. Hence, selecting the right plasticizer for a specific application is very critical to make the product softer. Plasticization can occur both internally and externally.
