Plasticizers: Types, Uses, Classification, Selection & Regulation
It is almost colorless and odorless oily liquid. It is very slightly soluble in water but soluble in alcohols, hexane etc. while miscible and compatible with all the monomeric plasticizers used in PVC compounding. Melting point: 43°C (45°F; 230 K) Boiling point: 244-252°C at 0.7 kPa.
Plasticizers for PVC | POLYNT
Some examples of plasticizers for PVC are represented by the following categories: Phthalates: they are characterized by a particular ease of manipulation and gelation and a high efficiency and volatility; they are among the most used molecules in the field of plasticizers.
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).
Research progress of novel bio-based plasticizers and their
Abstract Plasticized polyvinyl chloride (PVC) has been widely used in the world. Petroleum-based plasticizers especially phthalates have been the most common plasticizers used in PVC. However, the global petroleum resources are becoming scarce gradually, and the hygienic requirements for plasticizers are increasing. Owing to the negative impact of petroleum-based plasticizers on human health
Environmentally-friendly PVC Plasticizers (Non-phthalate
This page is DIC (formerly Dainippon Ink and Chemicals) 'Environmentally-friendly PVC Plasticizers (Non-phthalate Plasticizers)'. DIC is working to develop plasticizers (non-phthalate) that accommodate usage restrictions for Endocrine Disrupting Chemicals and food utensils, containers and packaging, and toys. Examples of major applications and representative product numbers of non-phthalate
- 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 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.
- How to choose a plasticizer?
- be blended together. This imparts the best attributes of both classes, resulting in optimal performance in the end-use application.The best way to select a plasticizer is to first determine what the critical performance parameters are for the end product application. Normally, one can determine the two or three most necessary properties in their
- Which phthalate is used as a plasticizer for PVC?
- DTDP is the highest weight dialkyl phthalate to be used as a plasticizer. It was widely used as a high temperature plasticizer for PVC until trimellitates came into existence. It needs high processing temperatures for compounding with PVC. Cost: Phthalates are used as PVC plasticizers since the earliest days of flexible PVC.
- What is a polymeric plasticizer?
- Polymeric plasticizers are typically made from aliphatic dibasic acids such as adipic acid and diols. They are primarily valued for their permanence. These plasticizers are generally classified as polyesters, not adipates. Many have low solvency for PVC and high viscosity. Both these factors can make processing f-PVC compounds difficult.
- What are the different types of phthalate plasticizers?
- Among them, the most common are: Phthalate Esters – Produced by esterification of phthalic anhydride or phthalic acid. Obtained by the oxidation of orthoxylene or naphthalene. Most commonly used phthalate plasticizers include: DEHP: Low molecular weight ortho-phthalate. Still the world’s most widely used PVC plasticizer
