Citroflex Plasticizers for Flexible PVC - ChemPoint
Vertellus Citroflex delivers excellent plasticizer performances in aqueous- and solvent-based polymers, including acrylic, methacrylic, ethyl cellulose, hydroxypropyl methyl cellulose, vinyl acetates, vinyl chloride, and urethane polymer systems. Available in either hydrophilic or lipophilic esters, formulators control the polymer system
Plasticizers - Chemical Economics Handbook (CEH) | S&P Global
Flexible PVC (and thus plasticizers) is found in the following applications: construction (flooring, wall coverings), electrical (wire and cable jacketing), consumer goods (toys, footwear, etc.), packaging, transportation (inside and outside of vehicles), furnishings, and medical uses (tubing, blood bags).
ROLE OF DIFFERENT PLASTICIZERS IN PVC PRODUCTS - LinkedIn
Sub Classification of plasticizers – 1. General purpose plasticizer [GP] - They provide desired flexibility to PVC, balancing overall quality with low cost. Examples are DIHP, DOP (DEHP), DINP...
The Long Goodbye to DEHP-plasticized PVC | mddionline.com
The idea of scrapping the use of polyvinylchloride (PVC) materials containing di (2-ethylhexyl)phthalate (DEHP) plasticizers is not new. However, despite such endeavors, both PVC and DEHP plasticizer still abound in a variety of products, including garden hoses, building materials, toys, and such medical devices as, catheters, feeding tubes, and IV sets.
Eliminating DEHP Plasticizer in Medical-Grade PVC
The plasticizers used to render PVC flexible constitute about a third of the vinyl compound by weight and have a significant effect on overall properties and performance. The most widely used plasticizer in medical applications, DEHP (di(2-ethylhexyl) phthalate), has been shown to engender biological activity when metabolized in rodents (though not in humans). As a result, there is pressure on
- Are plasticizers compatible with PVC?
- The molecular structure of plasticizers largely determines their effectiveness and compatibility with PVC. Plasticizers typically consist of large molecules that are capable of inserting themselves between PVC chains. This insertion effectively reduces intermolecular forces, allowing the PVC to become more flexible.
- What is the role of plasticizers in PVC?
- Understanding the role of plasticizers is crucial, as they significantly influence the properties and applications of PVC. They impact flexibility, durability, and processing efficiency. These characteristics make PVC a versatile material used across numerous industries, from construction to healthcare.
- Are PVC resins compatible with plasticizers?
- Compatibility between plasticizers and PVC resins is another fundamental aspect that determines the overall performance of the final product. 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.
- Are phthalate plasticizers good for PVC?
- Phthalate plasticizers have been the conventional choice in the PVC industry for many years. They improve the flexibility and processability of PVC, making it suitable for a wide range of applications, such as pipes, vinyl flooring, and medical devices.
- Is EPO a plasticizer for PVC?
- The results indicate that EPO is a potential plasticizer for PVC when pure and, by replacing 50% of DOCH, the PVC compound shows similar properties to pure DOCH, but better elongation at break and thermal stability. 1. Introduction
- Are bio-based plasticizers a good choice for PVC products?
- Utilizing biobased plasticizers enhances the eco-friendliness of PVC products while retaining the necessary performance characteristics. Furthermore, they often undergo a different metabolic pathway, potentially reducing toxicity concerns.
