Plasticizer - an overview | ScienceDirect Topics
Plasticizers are used to convert PVC, a rigid plastic, into a soft, flexible, and elastic material. A plasticizer that is compatible with PVC and exhibits low volatility, good permanence, and high efficiency is referred to as a primary plasticizer. A secondary plasticizer has the opposite characteristics of a primary plasticizer.
Analysis of Phthalates and Alternative Plasticizers in Gloves
Different types of protective gloves are employed, such as vinyl, latex, neoprene, or nitrile. Beyond these categories, protective gloves can also be classified according to the benefit
Plasticizers for PVC | POLYNT
About Plasticizers for PVC. The plasticizers are organic substances with various characteristics, whose main function is to intercalate the rigid polymer structures of material such as PVC for an easy movement and flexibility, making them more precisely "plastics." The presence of plasticizers in the PVC structure will influence different
ROLE OF DIFFERENT PLASTICIZERS IN PVC PRODUCTS - LinkedIn
1. General purpose plasticizer [GP] - They provide desired flexibility to PVC, balancing overall quality with low cost. Examples are DIHP, DOP (DEHP), DINP and DIDP. They can be used along with
Comprehensive Guide on Polyvinyl Chloride (PVC)
Mechanical Properties: PVC is abrasion-resistant, lightweight, and tough. Chemical Resistance: PVC is resistant to all inorganic chemicals. It has very good resistance against diluted acids, diluted alkalis, and aliphatic hydrocarbons. Some grades are attacked by: ketones and esters, chlorinated and aromatic hydrocarbons,
- 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.
- 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 are the different types of plasticizers?
- Plasticizers can be divided into several categories, including phthalate, non-phthalate, and biobased plasticizers. This categorization impacts their efficacy and regulatory compliance. The choice of plasticizer can influence the final properties of PVC, such as flexibility, tensile strength, and resistance to cracking.
- 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.
- How do plasticizers affect the performance of PVC products?
- Plasticizers influence the flexibility, workability, and durability of PVC products. Choosing the right type of plasticizer can enhance the performance characteristics of PVC while also addressing environmental and health concerns.
- Are phosphates a good plasticizer for PVC?
- Phosphates are primary plasticizers for PVC. They can be utilized as sole plasticizers or in a cost-optimized blend. Triaryl phosphates show excellent flame retardancy with low volatility. However, they have poorer low-temperature flexibility.
