Plasticizers. Plasticizers ensure elasticity and flexibility of polymer materials. But this is not their only benefit. Plasticizers also optimize, for example, the processing properties of polymer materials, which leads to improved product quality or even new properties. The choice of plasticizers depends on the demand placed on the finished
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
Effect of plasticizers and polymer blends for processing
Plasticizers depress the glass transition temperature (Tg) of polymers and produce a flowable material at lower temperatures. The use of plasticizers to depress Tg of lignin is important, since at high processing temperatures lignin crosslinks, making it intractable. The goal of this study was to assess plasticizers and polymer blends for the ability to retard a commercial softwood kraft
Determination of plasticizers efficiency for nylon by
The minimized molecular structures of the four plasticizers used in this study are shown in Fig. 1. It can be seen that while M4HB and BSA are rigid molecules due to the aromatic rings which are their main constituent, GMS is a very flexible molecule due to its long aliphatic chain.
How to Select the Right Plasticizer for Polymers?
Plasticizers are additives that increase the flexibility, extensibility, and workability of some plastic materials like PVC. These plasticizers are either liquids with low volatility or solids. They decrease the attraction between polymer chains, increasing the flexibility of the plastic material. What are the Requirements for Plasticizers?
- What is the role of plasticizers in polymers?
- The primary role of plasticizers is to improve the flexibility and processability of polymers by lowering the second order transition temperature . Plasticizers are actually low molecular weight (MW) resins or liquids, which form secondary bonds to polymer chains and spread them apart.
- What is a reactive plasticizer?
- Learn more. This review is about the reactive plasticizer. Plasticizers are small molecules with low molecular weight. These compounds typically have an esteric structure. The plasticizers reduce the glass transition temperature, and the viscosity of the polymer also enhances the flexibility and processability of polymer materials.
- 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 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.
- Are polymeric plasticizers a good choice?
- They can be designed so that they are highly compatible with the host polymer, and leaching and volatility issues have been significantly improved over traditional plasticizers. However, polymeric plasticizers are usually expensive and have lower plasticizing efficiency than most traditional plasticizers.
- 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.
