Uses of Phthalates and Other Plasticizers - U.S. Consumer
– Plasticizers are have low volatility – Plasticizers will lose the ability to improve flex ibility if the plasticizer is chemically attached to the polymer – For phthalate esters, the plasticizer range extend s from esters prepared from C4 alcohols to C13 alcohols. However because of high volatility, C4 - C6 phthalate esters are no
Eastman Plasticizer A to Z List - Eastman Chemical Company
Benzoflex181 is a water white alkyl benzoate ester with low odor, low viscosity and excellent compatibility with PVC. Benzoflex181’s principal use is as a low viscosity plasticizer for plastisol applications. Benzoflex 181 may also be used in other applications requiring a low viscosity, high solvating plasticizer.

Eastman Cellulose Acetate Propionate CAP-504-0.2 is a free-flowing powder with low odor, low color, and high hydroxyl content. It has a low viscosity (0.2 seconds) and an approximate propionyl content of 42.5 wt %. CAP-504-0.2 is compatible with many ink resins and solvents.
What is DEHP? Where is it used? Why is it used? | U.S. Plastic
Plasticizers are essential to make PVC flexible. PVC is naturally rigid, but plasticizers are added to make the tubing flexible and expandable while retaining its shape. DEHP is widely used because it is low cost, processes well, and has provided good end-use performance.
Tygon tubing
Tygon 2275 High Purity Tubing is a plasticizer-free material that is often used in sterile filling and dispensing systems and diagnostic equipment. This formulation is also considered to have low absorption/adsorption properties, which minimizes the risk of fluid alteration.
- Are polymeric plasticizers adipates?
- 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. Many have poor low-temperature properties and may be sensitive to moisture. Check out the table below for the benefits of polymeric plasticizers.
- 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.
- 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 natural product type plasticizers?
- Vegetable oil derivatives are the most widely used natural product type plasticizers. Products consisting of triglyceride esters of unsaturated fatty acids (e.g., soybean oil, linseed oil) in which the double bonds in the fatty acid residues have typically been epoxidized have been commercial products for decades.
- 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.
- 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.
