Structure Design, Performance Simulation and Plasticizing
Plasticizer is an important assistant in the production process of polyvinyl chloride (PVC), which can effectively improve the plasticity of PVC. However, the durability and plasticizing effect of traditional phthalate plasticizers need to be further improved. In this paper, a variety of copolyesters are designed and synthesized from succinic acid, hexanediol and other four different diols
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.
Plasticizers: Types, Uses, Classification, Selection & Regulation
Most common plasticiser chemistries include citrates, benzoates, ortho-phthalates, terephthalates, adipates, azelates, sebacates, and trimellitates. Plasticizers are the most common additives used in the plastics industry. But, selecting the right plasticizer for an application has always been a daunting task.
Structure Design, Performance Simulation and Plasticizing
The addition of a plasticizer to PVC can improve its workability, decrease its processing temperature, and achieve the desired toughness [9 – 12]. Plasticizer is one of the largest additives in terms of production and consumption [13]. It plays an indispensable role in providing high-quality plastic products for human beings [14]. For a long
What Plasticizers Do & How They Affect Properties | Osborne
PVC is one of the most durable materials in the world because of plasticizers added to it, lasting up to 50 years without damage. Because plasticizers can make the material stronger than before, PVC is largely used in the construction, automotive and wire and cable sectors.
- What is a plasticizer in PVC?
- A plasticizer reduces melt viscosity during processing. In PVC products, the glass transition temperature (Tg) and elastic modulus of PVC are also reduced. Liquids are usually called “plasticizers”, whereas solids like nitrile rubbers, compatible polyesters and some polyacrylates are called plastifiers or flexibilizers.
- What are plasticizers used for?
- These characteristics make PVC a versatile material used across numerous industries, from construction to healthcare. Plasticizers serve as essential additives in enhancing the performance of PVC. By reducing the glass transition temperature, they enable products to maintain functionality under various conditions.
- Why do we need plasticizers in polyvinyl chloride (PVC)?
- Plasticizers play a crucial role in the overall performance and usability of polyvinyl chloride (PVC). Their addition can significantly alter the mechanical properties of PVC, thereby expanding its application range.
- What makes a good plasticizer?
- A good plasticizer must blend uniformly with the PVC matrix, ensuring that it does not phase-separate or lead to inconsistency in the material properties. An effective means to evaluate compatibility is through the analysis of: Solubility: The plasticizer should dissolve in PVC without forming precipitates.
- What are the best value-added PVC plasticizer options?
- Let’s now turn our attention to three value-added PVC plasticizer options that exceed the emerging requirements of REACH and European Union (EU) regulation. VESTINOL® 9 DINP is a very cost-effective, general-purpose plasticizer very useful in soft PVC formulations with a broad processing temperature window.
- How do Bio-Plasticizers improve the mechanical properties of PVC?
- The primary mechanism involves reducing the glass transition temperature (Tg) of PVC, which is crucial for improving its mechanical properties. By lowering Tg, Bio-Plasticizers allow PVC to maintain its flexibility and ductility at lower temperatures, making it suitable for a wider range of applications.
