Current Status of Plasticizer Research | SpringerLink
In PVC gloves produced in earlier times, phthalate plasticizers were used by 80% among the overall plasticizers, including DOP, DBP, DIBP, BBP, DINP, etc. DOP is called an all-round plasticizer because of its advantages of high plasticization performance, good PVC compatibility, low exudation, low volatility, softness, high brightness, etc.
Effects of molecular design parameters on plasticizer
Abstract. Using all-atom molecular simulation, a wide range of plasticizers for poly (vinyl chlorid) (PVC), including ortho- and tere-phthalates, trimellitates, citrates, and various aliphatic dicarboxylates, are systematically studied. We focus on the effects of plasticizer molecular structure on its performance, as measured by performance
Research progress of novel bio-based plasticizers and their
Therefore, hyperbranched structure polymers are likely to use as high-performance plasticizers. At present, researchers have made attempts and efforts in this research direction. The bio-based hyperbranched molecular structure plasticizers that have been reported have considerable plasticizing properties and superior migration resistance [ 79 ].
Selecting Plasticizers for Adhesives and Sealants
Plasticizers are one of the commonly used additives in adhesives and sealants formulations. They improve the performance of adhesives by creating much-needed flexibility, optimizing viscosity, toughness, set time functionality, impact resistance, and even adhesion.
Plasticizers – Benefits, Trends, Health, and Environmental
Plasticizers soften the PVC to make it flexible and bendable. This opens up a huge range of possibilities for new applications. One of the main benefits of plasticizers is the durability they confer onto PVC applications, which can ensure high performances for up to 50 years.
- What are velsiflex plasticizers?
- Velsiflex plasticizers are high performance plasticizers. They are polar and monomeric in nature. In most cases, they provide superior performance compared to other plasticizers as it relates to polymer compatibility, efficiency and desired softness.
- 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.
- Is velsiflex a plastisol?
- As a vinyl plasticizer, Velsiflex® has the solvating power that affords ample formulating latitude for optimized PVC formulations. Typical plastisol applications include calendering, flooring, or automotive plastisol sealants. Velsiflex plasticizers are high performance plasticizers. They are polar and monomeric in nature.
- Who makes dibenzoate plasticizers?
- Velsicol is a world-renowned manufacturer of dibenzoate plasticizers and first introduced them in the 1950’s throughout the globe. Velsicol played a key role, as a dibenzoate supplier, in the conversion of phthalate plasticizers to non-phthalate plasticizers.
- How to choose a plasticizer?
- The choice of the plasticizer is dependent on the requirements that have to be met for the final product and the conditions around that product’s use. This may include low volatility, high permanence, low temperature flexibility, flame retardancy, high thermal stability and saponification resistance.
- How do plasticizers affect polymers?
- Plasticizers are substances which, by virtue of their polar or polarizable structure, weaken the secondary valence forces of polymers. 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.
